Even the best can slip sideways in (out) of the slot...
SnapOn's have wedge shaped tips as are Hazets (the latter have or had a nice anti-slip grind or coating on the tips)
PB Swiss uses a parallel sided tip - like a hollow grind on gunsmith's screwdrivers
Zeke, I hadn't heard the criterion in post 12
Brownie points if you can guess where slotted screws are used on 911s...
