But working on electronics having JIS screwdrivers is very helpful. I finally bought a set of bits that see regular use. Not camming out of those tight cover screws anymore.
Fluke has some nice screwdrivers got a few pieces from a English guy when we work together on Carrier A/C Absorbers machine , Tower Hobbies got some good stuff used there tools when i race 1/10 scale gas cars .
Most peoples don't know the existence of JIS screwdrivers and a lot of them confuses Phillips & Pozidriv too.
My work colleagues are still confusing Phillips & Pozidriv, they regularly broke drivers and kill screw heads.
Since I've got a set of JIS I haven't killed any screw head on Japanese equipment.
