I have one of these that I use on a daily basis. I LOVE it. The little wing-looking flappy things can be detached, which is helpful. It has a really nice geared opening motion to it, and with all the hardcore work I’ve done with it (including but not limited to prying, cutting and shaving bits of metal) it hasn’t so much as scratched the finish. I am seriously contemplating buying a second one in case I lose the first one, because I’m sure as hell not worried about it breaking.
