Review on KNIPEX 98 20 35 Screwdriver by Ryan Lindstrom

I've never owned anything from Knipex, but I've seen their tools in other tool boxes. They have a reputation for quality products. I didn't try to test the insulating properties; I'm sure he's as good as anyone, but I never rely on him. Hardness (wear protection) and toughness are good; I closed the wires in the terminal blocks for 4 hours, the reason for the purchase. The end was still sharp and square. I twisted the hardened screw like any sane person would, and the tip didn't deform; The material and heat treatment seems to be as good as a quality Allen key (hex key), my benchmark for "the best". You will not regret buying this screwdriver.
