Just got mine today. The knife is beautiful and the flipping action is satisfying. I'm afraid it might be a bit too thick but we'll see as I use it for the next few days. I think it would be fine in a front pants pocket if you only had a couple of keys (which I do), but I also have a key fob and AAA flashlight attached. Doesn't quite sit at the bottom of my pocket as comfortably as I would have liked. But I'll give it a shot. Worst case I'll buy a separate KeyBar just for this+ accessories, and make a DIY utility knife.
