In this short video we're going to demonstrate the difference between JIS screwdrivers tips and Phillips screwdriver tips.
JIS Screwdrivers are manufactured to Japanese Industrial Standard. JIS designed the tips of their JIS screwdrivers to actually fit the screw. When you get your hands on your first screwdriver that meets Japanese Industrial Standards You will quit stripping the screw heads and start extracting the screws.
