Spintite Nut Drivers

I was looking for nut drivers to replace lost Craftsman tools and found these old wood handled Spintites at Liberty Tool for the princely sum of 40 cents each. 

A quick Google search and we find the Spintite name was a trade name dating from 1923, used by Walden Worcester and later Stevens-Walden. They were an early manufacturer of automotive specialty tools like sockets and wrenches. Walden remained in business until some time in the 1990s.
