Introduction to Tool Logos

This page will present a table of tool logos, which are symbols or designs marked on tools to identify the maker. In some cases the logos are also registered trademarks (as noted in the table), but in general are simply informal marks chosen by the manufacturer to identify their tools. Our logo images have been extracted from tool photographs, trademark filings, or published sources.

In the table below, the "Shorthand" column shows a nickname we've assigned for convenience of reference, and these names have been chosen carefully to allow the logo images to be found easily using an index search. Most logos consist of one or more letters in a geometric outline or other recognizable shape, and our naming convention tags the image with "XYZ-Outline", where "XYZ" are the observed letters, and "Outline" is the enclosing shape. (If there's no obvious outline, we have appended "-Logo" to the letters.)

The "Company" column will generally identify the company using the logo and link to our article for the company. Logos for unknown forge-marks or tools from unknown makers will point to a section where we've gathered whatever information is available.

In a few cases "Multiple Uses" will appear instead of a specific company name, indicating that the same (or nearly identical) logo was used by multiple companies. For these cases the site index under "Logo Images" will have links to the "Tool Identification" sections of the companies known to use the mark.

The "Reg TM" column indicates whether the logo was registered as a trademark, and the "Forge Mark" column indicates whether the logo appears as a raised symbol on a forged piece, after having been incised into the forging die. Forge marks were often used on contract manufacturing production to identify the maker.

Our intention is that this table of logo images (along with the tables of Trademarks and Brands) should be sufficient to identify the tools made by any of the companies noted on this site, within the scope of our coverage. If any of our readers have found additional logos that should be added, please let us know via email.

Tips for Searching

If you're trying to identify an unknown logo, it may be faster to use an index search rather than looking through all of the images. Try entering the observed letters followed by a dash and the outline shape in the search box. (Popular outlines are Triangle, Diamond, Hex, Oval, and Circle, plus Shield and Horseshoe.)

If you're not sure of the order of the letters, a search for the outline shape followed by "image" will show all logos with that outline. For example, an index search for "circle image" will show all of the logos with text in a circle.
