Quote: I borrowed a KD 2190 from a guy at work, and it works perfect. I've never seen another one made quite like it. I am now on the lookout for a good deal on one to get for myself. I messed around with some of those typical ones and they all slipped. I wouldn't mind the hydraulic style ones, but they sure are pricey for no more than I would use them.
That style works the best I think, I have a similar one that's about 30 years old.
