Retired Mechanic here, I will be selling a bunch of tools, many are engraved, most are not, please look at the pictures. Many Craftsman tools from back when Craftsman was good quality and not today's trash. Because the large amount of tools I owned, and the fact that I only used a small specific number of them day to day, many pieces are practically new or lightly used, other than some grease or a bit of dirt.

Thanks!
