Daido Corporation U.S.A.


Table of Contents


Introduction

The Daido Corporation was the U.S. subsidiary of a Japanese export marketing and distribution company, with products including automotive and motorcycle parts, power transmission chains, hand tools, and other metal products. In the mid 1950s Daido began selling Japanese hand tools under the "Allenite" brand, and then later acquired the "Truecraft" brand from an American company. Daido's Truecraft line went on to become the best known brand of Japanese tools in America.


Company History

The Daido Corporation U.S.A. has a rather complex history, reflecting its role as part of a multinational company with multiple partners in Japan. Our primary interest here is in the development of Daido's hand tools business in America, but in order to establish the proper context, we have provided a brief history of Daido's Japanese parent Meisei Tsushō in a separate article.

Early Operations

In October of 1951 Meisei Tsushō established the Daido Corporation U.S.A. as a subsidiary in New York City. At that time Daido was only the sixth Japanese company to incorporate in New York in the post-war era.

Currently we don't have much information on the company's early operations. We do know that by the early 1960s Daido had distribution centers in San Francisco, Chicago, and New York, so presumably setting up the distribution network would have been an important early priority.

We recently (2023) discovered that during the 1950s Top Kōgyō made adjustable wrenches for the Truecraft Tool Company of Chicago. Top Kōgyō was a major tool manufacturer in Japan and a frequent production partner for Daido, which suggests that Daido probably made the arrangements for the production, and likely would have acted as the distributor.

Top Kōgyō may have provided contract production for other U.S. companies as well, and their production can be identified by the "TOP" forge mark.

By 1954 Daido was offering hand tools under the "Allenite" brand, based on the first use date in a later trademark filing. Currently we don't have much information on this earlier brand, as no advertisements have been found, but we do have a few examples of the tools in a later section.

The Formation of the Truecraft Tool Division

In 1962 Daido acquired the Truecraft Tool Company of Chicago with the intention of using the "Truecraft" brand for a new line of hand tools. The Truecraft Tool Company was a small company selling tools such as pliers, adjustable wrenches, hammers, and hatchets, with customers probably including hardware stores or other small retail outlets.

We haven't yet found the exact date of Daido's acquisition, but it appears to have been sometime in early 1962, based on the announcement at the left.

[1962 Announcement of Daido Truecraft Tool Division]
Fig. 1. 1962 Announcement of Daido Truecraft Tool Division.

The scan in Fig. 1 shows Daido's announcement of its new Truecraft Tool Division, as published on page 118 of the June 28, 1962 issue of Hardware Age.

Note that the text mentions "TOP" tools twice, which we think is a reference to the trademark brand used by the Top Kōgyō Company. This suggests that Top Kōgyō may have been Daido's first production partner for the Truecraft line.

The text also notes (third paragraph from the bottom) that Truecraft Tool would continue to supply various tools. Truecraft Tool is not known to have had any manufacturing facilities of its own, so we take this statement to mean that whatever contractual supply agreements were in effect would continue under Daido.

To further clarify the role of the prior company after the acquisition, an ad on page 127 of the January 24, 1963 issue of Hardware Age lists the Truecraft Tool Company as a Daido representative, with the former owners Norman Kaufman and Paul Kaufman as contacts!

This strongly suggests that the acquisition of Truecraft Tool may have been just a purchase of the Truecraft trademarks, with the company owners free to continue as sales representatives under the same company name.

After reviewing this announcement and some of the company's subsequent advertisements, it appears that Daido initially had only modest aspirations for its Truecraft division, with a limited selection of tools intended for customers such as hardware stores or similar retail outlets. The announcement itself mentions only adjustable wrenches, pliers, and hammers, and ads in the next couple of years extended this only slightly to include socket wrench sets.

The early ads make it clear that the company intended to compete on the basis of low prices, but also suggest that Daido may have underestimated the intense competition in the hardware trade.

For example, an advertisement on page 133 of the March 21, 1963 issue of Hardware Age offered a No. SW32 32-piece hex-drive socket set made of carbon steel, functionally similar to sets that had been sold in vast quantities by Duro/Indestro (and others) since the 1930s. It's hard to imagine such sets would have sold in meaningful quantities in the 1960s, given the many other inexpensive socket sets available.

[1964 Ad for Daido Truecraft Tools]
Fig. 2. 1964 Ad for Daido Truecraft Tools.

The scan in Fig. 2 shows an example of an early ad for Daido's Truecraft Tool Division, as published on page 103 of the March 5, 1964 issue of Hardware Age.

The illustration shows pliers, an adjustable wrench, and a socket set, and the text highlights the triple chrome plated finish and the prospect of higher profits for the reseller. Distribution locations are noted in New York City, Chicago, and San Francisco.


Combination Wrenches

Truecraft was probably offering combination wrenches by 1963, but the earliest ad we've found so far is from 1966.

[1966 Ad for Truecraft Combination Wrenches]
Fig. 3. 1966 Ad for Truecraft Combination Wrenches.

The scan in Fig. 3 shows an illustration for a combination wrench set within a full-page ad for Daido's Truecraft Tool Division, as published on page 419 of the July 21, 1966 issue of Hardware Age.

The caption notes that sizes up to 1 inch were available.

In the illustration the middle part of the shank appears to be have been polished, but due to the low resolution of the image it's hard to tell whether the shank is polished or if there is a raised polished panel.

The earliest Truecraft combination wrenches are believed to have been models with a flat shank and an odd polished area in the center of the shank, which we will refer to as the half-polished style. Examples of wrenches in this style can be seen as the Truecraft B-105 5/8 Combination Wrench and Truecraft B-106 11/16 Combination Wrench.

When we first ran across wrenches in this style, we thought that they had been made by the Truecraft Tool Company before the Daido acquisition, since our wrenches were not marked for Japan and did not resemble the known Truecraft combination wrenches.

However, the CWC web site has very similar examples of Truecraft combination wrenches in this half-polished style, but with a "Japan" marking. In addition, one example of a similar open-end wrench with a half-polished shank has a "TOP" marking, indicating production by Top Kōgyō.

Based on further observations of numerous online photographs, we can state that most wrenches of this style were marked "Japan", so it's virtually certain that the wrenches were made in Japan.

But this raises a problem in that no examples of similar production for the Japanese market are known. Wrenches with flat shanks were not popular in Japan during the 1960s, and we can't point to a particular manufacturer as having made this style of wrench. For now, the maker of these early combination wrenches is a mystery.

One further observation to note is that the known examples of half-polished style combination wrenches are all dual marked with both B-xxx model numbers matching those used in the 1973 catalog, plus SW-x numbers that appear to be an earlier series of model numbers. The SW numbers start at SW-1 for the 3/8 wrench, indicating that combination wrenches must have been available when the system was first planned.

The use of the B-xxx numbers shows that the alphabetic-prefix model number system was already in use by the mid 1960s, although we don't know if model numbers were being consistently marked on all tools at that time.


A Pivot to the Professional Market?

A notice in the May 1, 1968 issue of Hardware Age announced the availability of Truecraft's 16-page catalog T68-1, which included their new "flexsocket" wrenches. This was the first notable departure from typical hardware-store tools, as this type of wrench would be of greater interest to a professional mechanic. (As a side note, we refer to "flexsocket" wrenches as "flex-box combination wrenches", since they offer two different openings of the same size and are thus a type of combination wrench.)

Another example of the move towards higher-end markets can be seen in a notice on page 188 of the September 15, 1971 issue of Hardware Age, which illustrates a 19-piece chrome-moly socket set with cold-forged sockets.

The Allenite Tool Company

In 1970 Daido U.S.A. filed a trademark application for "Allenite" with the first use date stated as 1954. The 1954 date would make this Daido's first U.S. brand, and originally we thought that the use of "Allenite" would have been phased out after Daido acquired the "Truecraft" brand in the early 1960s.

However, we recently (2023) discovered that Daido U.S.A. created a subsidiary Allenite Tool Company in Lincolnwood, Illinois, and the Allenite company is known to have filed copyrights related to chrome alloy socket sets in the 1970s. This shows that the Allenite brand continued in use much longer than originally thought, and would have overlapped significantly with Daido's primary Truecraft brand.

Currently we haven't found much information on the Allenite Tool Company, but will add information as it becomes available.

The Steelcraft Tool Company

By 1971 Daido U.S.A. had acquired the Steelcraft Tool Company, a maker and importer of tools and hardware with roots going back to the 1920s. Steelcraft continued to operate as a division of Daido, and their offices and warehouse were moved to Daido's New Jersey facility.

A 1971 catalog from Steelcraft includes a foreword from its president Martin H. Rieger, who had previously founded the Award Tool Company before joining Steelcraft in 1969.

Daido used Steelcraft as an outlet for another tool brand "Cen-Tech", intended as a lower-priced alternative to its main Truecraft line.

The 1973 Truecraft Catalog

In 1973 Daido released Truecraft catalog T-73-1, which is currently our earliest catalog resource for the company. The catalogs lists a wide variety of tools including adjustable wrenches, pliers, sockets and drive tools, open-end wrenches, combination wrenches, flex-box combination wrenches, pipe wrenches, screwdrivers, hammers, and other items. Most tools are noted as being made from some type of chrome alloy steel.

All tools are listed with alphabetic-prefix model numbers, such as K358G for lineman's pliers or B105B for combination wrenches.

The catalog states that the tools are made in "our factories in Japan, Europe, and the U.S.A.", which we take as a statement about their production partners' factories. Some of the illustrations show markings that identify the particular maker — several pliers are marked "TOP", lineman's pliers show the symbol for Three Peaks Giken, some pipe tools are marked "Super Ego Spain", and some illustrations of open-end and combination wrenches show "Palmera", the trademark of Juan Vollmer S.A. of Irun, Spain.

The catalog further notes that chisels and punches are made of forged alloy steel by American manufacturers. And if you get out your magnifying glass, page 23 offers a 5-piece screw extractor set made by Enderes Tools of Albert Lea, Minnesota. As promised, factories in Japan, Europe, and the U.S.A.

Inconsistency in Tool Markings

The 1973 catalog confirms that most of the Truecraft line was made with chrome alloy steel, and with this knowledge we want to point out an unfortunate lapse that may have limited the acceptance of the Truecraft brand. Specifically, this is the fact that many Truecraft tools were marked "Drop Forged Tool Steel" when they actually were made of chrome alloy steel.

Under U.S. trade laws the term "alloy steel" has a specific meaning, and the U.S. Federal Trade Commission (FTC) has been known to bring enforcement actions against companies that improperly mark their tools. The term "tool steel" is a broader category that includes the standard alloy steels used for tools as well as non-alloy steels such as AISI 1045 carbon steel or AISI 1340 carbon manganese steel.

Simply stated, no American tool maker would mark their tools "Drop Forged Tool Steel" if the tools were actually made of chrome vanadium or chrome molybdenum steel; it would be like calling your products "Medium Quality" after paying for top quality materials.

By the 1960s tool buyers in the U.S. were no longer concerned with the relative merits of chrome vanadium vs. chrome molybdenum steel, and a number of makers had already switched to non-specific trade names for alloy steel, such as Armaloy, Barcaloy, Crestoloy, or Diamalloy.

But there was still a broad perception that alloy steel tools would be of higher quality than non-alloy tools, and if presented with a wrench marked "Drop Forged Tool Steel", most buyers would probably assume that the tool was NOT made of alloy steel. Otherwise, why wouldn't the manufacturer have marked it "Alloy Steel"?

Examples of the inconsistent markings on Truecraft tools can be seen in the figures below. The flex-box combination wrenches here and here were both made by AIGO Kōgyō, but one is marked "Chrome Vanadium Drop Forged" while the other is "Drop Forged Tool Steel".

Wrenches from maker "Palmera" here and here are marked "Alloy Steel" or "Chrome Vanadium", but all combination wrenches before 1975 from maker AIGO Kōgyō are marked "Drop Forged Tool Steel".

A later flare-nut wrench from an unknown maker is marked "Chrome Vanadium Drop Forged".

As the owner and manager of the Truecraft brand, Daido U.S.A. should have enforced uniform markings for the tools, so that all alloy-steel tools were marked with "Drop Forged Alloy Steel" or something comparable.

Numeric Model Numbers

In the mid 1970s Daido U.S.A. changed from its alphabetic-prefix model numbers to an all-numeric system with four or five digits. The change occurred around 1975, in between catalog T-73-1 (with alphabetic prefixes only) and catalog T-77-1, with both old and new numbers.

This change didn't affect the tools directly, but provides us with a convenient way of distinguishing between older and newer production.

Production of Tools for Export

As an export marketing and distribution company, Daido would be expected to source tools from a number of different Japanese companies, as well as tool companies in other parts of the world.

Most of the production was done in Japan, but two production partners in Spain have been identified (using the "Palmera" and "Super Ego" brands), and one U.S. manufacturer (Enderes Tools) is known as well. (The 1973 catalog noted factories in Japan, Europe, and the United States.)

A notice on page 34 of the November, 1976 issue of Hardware Age states that Truecraft had acquired a manufacturing facility in Newark, New Jersey previously owned by Vari-Plex, and was planning to begin making screwdrivers in October. The text also mentions that this was the company's first manufacturing plant in the United States.

As we learn more about the various Japanese tool makers, we hope to be able to determine which companies produced tools for the Daido brands. Japanese companies known to have supplied tools to Daido include AIGO Kōgyō, Three Peaks Giken, and Top Kōgyō.

Later Operations

The Truecraft Tool Division closed sometime in the early 2000s. As some point we hope to offer some discussion of possible reasons leading to the closure, but for now will note that the major factor was probably increased competition from Taiwanese tool makers. (Our article on Lea Way Hand Tool has background information on Taiwanese tool makers.)

In June of 2002 Daido U.S.A. changed its name to Advantech International, Inc., and the company remains in operation today as a provider of automobile, motorcycle, and industrial products, as well as market development services. Further information can be found at the Advantech International [External Link] web site.

The Japanese parent company still holds active trademarks for Truecraft, so it's possible that the brand could be revived at some point. (See our article on Meisei Tsushō for further information.)


Trademarks

Daido U.S.A. was very prolific in its trademark activities, and the table below shows only a fraction of the marks registered. (Daido had many lines of business apart from the Truecraft hand tools line.)

The parent company also registered Japanese trademarks for Truecraft and related brands.

Daido U.S.A. registered "Allenite" and "Truecraft" as its primary brand names for hand tools. The "Truecraft" mark was originally registered by the Truecraft Tool Company of Chicago and then acquired by Daido around 1962.

Daido later registered "Cen-Tech" (1973) and "PROMATE" (1981) as alternate brands for hand tools to be sold at lower prices.

Truecraft Hex Logo. By 1973 Daido U.S.A. was using a stylized form of "TRUECRAFT" with a hexagon between "TRUE" and "CRAFT", which will be referred to as the Truecraft Hex logo. This logo was printed on every page of the 1973 Truecraft catalog.

We haven't found a trademark registration for this stylized form, but the 1993 trademark #1,807,104 used the hex logo in "TRUECRAFT TOOLS". In addition, the Japanese parent company did register a trademark for the Truecraft Hex logo in 1994.

At some point the Truecraft Hex logo began to be marked on wrenches, but we're not sure whether this was consistently used by all production partners. The Truecraft Hex logo has been observed only on tools with all-numeric model numbers.

The following tables show some of the Japanese and U.S. trademarks related to Truecraft.

Manufacturing Dates

Truecraft tools were made over a fairly long period, from the early 1960s until around 2000, and it would be desirable to be able to estimate the production date for the tools. In general Truecraft did not provide a date code on the tools, although there may be exceptions for certain manufacturers.

The following list will offer some guidelines for estimating the manufacturing date of Truecraft tools.


Production Characteristics

Since Truecraft tools were made by a number of different manufacturers, one of our central problems is to identify the various makers. In this section we will look at various production characteristics observed on the known examples, and these will then assist in identification.


References and Resources

Photographs and observations of particular tools are based on items in the Alloy Artifacts collection.

CWC

Historical information on Japanese tool companies can be found (in Japanese) at the コンビネーションレンチ・コレクション Combination Wrench Collection [External Link] web site. We will refer to this reference as "CWC" in the text.


Catalog Coverage

We have several Truecraft catalogs from the 1970s and 1980s, as noted below.

Truecraft is known to have published a catalog in 1968, but currently we don't have access to any catalogs prior to the 1970s, which limits our understanding of the early development of the Truecraft brand.

If any of our readers have Truecraft catalog materials from the 1960s, please let us know via email.

Adjustable Wrenches

We have a substantial selection of Truecraft tools available, including adjustable wrenches, wrenches, pliers, and socket tools up to the 1 inch drive size, and the following sections will be expanded as time permits.

Some of the examples here are marked with alphabetic-prefix model numbers, the numbering system in use from around 1966 until around 1975. In this system the prefix indicates the type of tool, such as "A" for open-end wrenches or "B" for combination wrenches.

Adjustable wrenches were assigned an "F" prefix in the earlier numbering system, followed by a 2xx number where xx is the nominal size in inches. For example, a 10 inch wrench would be model F210.

After around 1975 the "F" prefix was dropped but the number part remained unchanged.

Fig. 6. Truecraft F208 8 Inch Adjustable Wrench, with Insets for Edge View and Back Side Detail, ca. 1960s to 1975.

Fig. 6 shows a Truecraft F208 8 inch adjustable wrench, marked with "Drop Forged Tool Steel" and "Top" forged into the shank, with "Truecraft Tool" and "Japan" forged into the back side.

The back side is also stamped with the "F208" model number on a small raised panel.

The overall length is 7.9 inches, and the maximum opening is 0.9 inches. The head thickness was measured at 0.47 inches.

The finish is chrome plating with polished faces.

The leading "F" of the model number indicates production before around 1975.

The "Top" marking indicates production by the Top Kōgyō Company. The forged-in code "8-84" below the "Top" marking resembles a date, but the meaning is not known.


Open-End Wrenches

Daido offered open-end wrenches under the "Allenite" brand probably beginning in the mid 1950s, although no advertisements or catalog listings have been found yet.

Truecraft brand open-end wrenches were probably available by the early to mid 1960s.

The next two figures show examples of Truecraft tools marked "Palmera", a registered trademark of Juan Vollmer S.A. of Irun, Spain.

Catalog T-73-1 from 1973 illustrates open-end wrenches with depressed panels like the tappet wrench of Fig. 9 below, but illustrates combination wrenches with raised parallelogram panels as in this next figure. We think this means that production from the Palmera brand was in transition to the parallelogram style.

Both sides are also stamped with the fractional sizes.

The overall length is 8.1 inches, and the finish is chrome plating with polished faces.

With the hypothesis that open-end wrenches were transitioning to raised parallelogram panels in 1973, the old-style model number and new-style panels for this wrench provide a mid 1970s production date estimate.


Truecraft A104B 9/16x5/8 Tappet Wrench

[Truecraft A104B 9/16x5/8 Tappet Wrench]

The overall length is 7.4 inches, and the finish is chrome plating with polished faces.

This wrench was made in the early forging style at the Juan Vollmer S.A. factory, suggesting production before 1974.


Combination Wrenches

Daido offered combination wrenches under the "Truecraft" brand probably beginning around 1963.


Truecraft Early B-105 5/8 Combination Wrench

The next two figures show examples of early Truecraft combination wrenches with an unusual style featuring a flat half-polished shank.

Both wrenches are marked with B-xxx model numbers matching the numbers used in the 1973 catalog, showing that the alphabetic-prefix model number system had been developed by this time.

In addition, the wrenches are marked with SW-x numbers, apparently an earlier model number series. Observations of other wrenches of this style confirm the consistent use of both B-xxx and SW-x numbers, with the SW models ranging from SW-1 for a 3/8 wrench up to SW-14 for the 1-1/4 inch size.

The overall length is 8.0 inches, and the finish is chrome plating with polished faces.

The shank also has a "5" code forged into the back side.

Note that this wrench does not have a "Japan" marking. Since Japanese law is strict about requiring a country-of-origin marking on tools made for export, the absence of the "Japan" marking on this wrench is unusual, but may just be an accidental omission at the factory.

Most other examples of combination wrenches in this style have been observed with a "Japan" marking.

Sockets and Drive Tools

Socket tools were among the first tools offered by Daido beginning in the 1950s. Initially the "Allenite" brand was used, but the tools then transitioned to the "Truecraft" brand in the early 1960s.

Currently we don't have any information on how early sales of the "Allenite" tools were arranged, as no advertisements for this brand have been found.

A 1964 advertisement for Truecraft tools offered socket sets in 1/4, 3/8, and 1/2-drive. By 1973 socket tools were available up to 3/4 drive, and the 1979 catalog offered the new 1 inch drive size.


1/2-Drive Socket Tools

The ratchet mechanism uses a 24-tooth gear with dual pawls, giving it a soft action with little backdrag.

This ratchet is quite similar to the Penens 1661 Ratchet, which may have served as the design model for this tool.

This ratchet was still in production in the mid 1960s — with a close look at the 1964 Truecraft Ad this ratchet can be seen in the illustration.

The numeric model number and plain "Truecraft" marking suggest production from around 1975 to the early 1990s.

The ratchet mechanism uses a 42-tooth gear with a single-action pawl. The mechanism is held in place by a flat coil spring and can be removed for cleaning or replacement.


Truecraft 6-Piece Indexable Ratchet Kit

Some of our readers may be familiar with the idea of an indexable ratchet, which usually just means a ratchet with a head that can be offset at various angles. Typically they're used to work around overhead obstructions that prevent access by ordinary ratchets and extensions. It's the kind of tool that you probably won't need very often, but when you need it, you need it badly.

This next tool takes the concept of "indexable ratchet" to a whole new level though: a six-piece ratchet kit with parts held together by spline drives, allowing the creation of a myriad of special-purpose ratchet-and-handle configurations.

[Truecraft 3/8-Drive 6-Piece Indexable Ratchet Kit]
Fig. 39. Truecraft 3/8-Drive 6-Piece Indexable Ratchet Kit, ca. Late 1990s.

Fig. 39 shows a Truecraft 3/8-drive 6-piece indexable ratchet kit, consisting of a 16730 3/8 drive fine-tooth ratchet head, a 16731 spline-drive flex-head handle, a 16736 spline-drive short offset arm, a 16740 spline-drive long offset arm, a 16750 spline-to-spline 2 inch extension, and a 16780 spline to 3/8-drive adapter.

Each piece is stamped with the "Truecraft" Hex logo and "Japan" plus the model number.

The kit is supplied in a plastic organizer measuring 9.0 inches long and 3.1 inches wide. The tools are finished in chrome plating.

Currently we don't have a catalog reference for this ratchet kit, but the kit was described and illustrated in a notice published on page 96 of the October, 1997 issue of Popular Mechanics. The notice cited a $190 list price.

The use of the "Truecraft" Hex logo marking on the tools in this kit is consistent with a late 1990s production date.


Truecraft 16731 Spline-Drive Flex Handle

[Truecraft 16731 Spline-Drive Flex Handle]
Fig. 40. Truecraft 16731 Spline-Drive Flex Handle, with Inset for Back Side, ca. Late 1990s.

Fig. 40 shows the Truecraft 16731 spline-drive flex handle from the indexable ratchet kit, stamped with the "Truecraft" Hex logo and the model number on the shank, with "Chrome Vanadium" and "Japan" on the back side.

The back side also has a "Pat. Pend" notation.

The overall length is 9.0 inches, and the finish is polished chrome.

The spline drive has 18 teeth, providing rotational increments of 20 degrees for the tool configurations.


Truecraft Flex Handle with Ratchet Head

The next figures show some of the many possible configurations of the indexable ratchet kit.

[Truecraft Flex Handle with Ratchet Head]
Fig. 41. Truecraft Flex Handle with Ratchet Head.

Fig. 41 shows one of the configurations of the Truecraft indexable ratchet kit, the 16731 flex handle connected to the 16730 ratchet head.

The 18 teeth of the drive splines provide 18 possible positions for the ratchet, and the ratchet head can be turned over for a total of 36 configurations. (Although there's some redundancy since the flex handle can be flipped over.)


Truecraft Flex Handle with Short Arm and Ratchet Head

[Truecraft Flex Handle with Short Arm andRatchet Head]
Fig. 42. Truecraft Flex Handle with Short Arm and Ratchet Head.

Fig. 42 shows another possible configuration of the Truecraft indexable ratchet kit, with the 16731 flex handle connected to the 16736 short offset arm, and the 16730 ratchet head connected to the offset arm.

The two splines provide 324 configurations, although some positions are blocked by the vertical offset of the arm. In addition, both the arm and the ratchet can be flipped over, giving up to 1,296 configurations. But don't worry, we're not planning to show photographs of all possible configurations!
