Craftsman Wrench Logos

Craftsman sourced their hand tools from a variety of different manufacturers over the years. They can (mostly) be dated and identified by the alphabetic logo included on the tool. This first table identifies the makers through 1947. After that date, things got a bit more hectic and that data is included in the second table.
