AFTE Store - New Screwdrivers, Production and Identification

The author obtained screwdrivers from seven tool manufacturers (Stanley, Rosco, Upson, Mephisto, Great Neck Saw MFRs,Vaco Products, & XCELITE) to determine if manufacturing methods would lead to mistaken identifications. Author concludes that screwdrivers vary enough to identify a toolmark back to the specific tool. Includes photos of working surfaces of screwdrivers.
