JIS screw drivers

[Gone in 60]

Very informative, Tev! I had just visited a good friend who restores early Phantoms. I was using his drill press and bench grinder to whip up a few box mounting plates for our company bikes. The tool chest nearest to the drill was labeled Whitworth, and his collection is necessarily impressive for his work. 

Plus, I get the question at my other job… “are these metric?”
