Ran into it in motorcycle repair research. Submitted because this explains why I’ve been annoyed and cursing “cheap screws” in electronics as they stripped on me for 20+ years. And why I settled on the driver with the colored tip as my favorite. Apparently I own one random JIS driver, probably scrounged from a yard sale or family member’s junk drawer.
I have a set of the acetate-handled Vessel drivers that I found out of total dumb luck at a Princess Auto. Essential for working on a Honda; I’ve saved so many screws that otherwise would have had to come out with a left-handed drill bit or easy-out.
