Review on Wera 05118066001 Screwdriver Electronic Applications by Will Schimmel

This small 1.5mm hex saved the day when others failed. Just recently I thought I had a broken grub screw in my guitar bridge. All of my other Bondhus L-keys (and even Wera) couldn't move without turning. I was about to give up and grab the drill, but as a last resort, I tricked this guy and he grabbed it right away. The shank is thicker than any standard L-wrench, and the shape of the screwdriver allows for more consistent pressure and torque than an L-wrench. Yes, it's expensive for a single hex, but it saved me many hours of trouble. Anything under 3mm and I'll take them first if space allows. It's 100% worth the price if you deal with small hex bolts on a regular basis.
