Here is something I did when folks are talking about smoothness. The U H I have is what I think smooth should be. No hitches in the giddyup to open the knife. No pauses no grinding, squeaking etc.etc. But it does take thumb pressure to open the knife. I like the knife this way cause when I open it I want to know I opened it. Now I loosened the pivot pretty good to the point where it flew open with a very slight wrist flick. I also noticed when doing this I would get side to side blade play, quite substantial actually when the blade was at the half way point. Kind of floppy. BUT when the lock engaged it was nearly as solid as a rock. Minuscule bit of side to side when locked, but side to side play none the less. Would it close accidentally nope. I cracked it pretty good on the side and on the spine. Matter of fact hitting it like that took a wee bit more of the play out of the blade when I would put it to the half closed position. Not all but was better than when initially the pivot was loosened.
I still want to know what you all use folders for. I don't know if I quite believe that someone used a folder to cut in a cat door in a door unless it was hollow core door or something like that. Again I just don't see someone using a folder for that task, maybe a keyhole saw or something. I am more than satisfied with the U H so much so I am going to get another and even maybe a few more, I like them that much and they don't break the bank. keepem sharp
