I found a screwdriver patented by Harry F Phillips of the Phillips Screw ompany in 1935
I wonder if this was the start of the most used fasteners in the country?
Another screwdriver i found is patented by Harris J. Cook of stanley works IN 1931 it is stamped Harris Cook not Stanley.
Yesterday I opened a foot locker full of screwdrivers. the only times it has been opened for almost three years was to throw screwdrivers in. I am having fun ,almost like santa was here .bob w.
