I just got my Urban Trapper today. It's a neat knife. It's definitely one of those knives where it's difficult to get an idea of the size until you have it in your hand.
Mine came with a moderately ugly/fairly unpretty edge bevel, but boy is it screaming sharp! The action was very gritty. Whether it was the bearings or the detent ball, I don't know, but I took it apart to clean and grease it. I ended up only cleaning the detent ball, because I really did not want to try to remove all those tiny bearings. I did as much as I could to keep them in the races, and the ones that escaped were a pain to get back in. After getting the knife back together with fresh grease, the action was silky smooth, and I could actually flip it (with a certain technique).
I ended up taking it apart a second time, because I wanted to increase the lock bar tension a little. Even with full lock engagement now, there is some lock-flex, I can easily flex the blade so it comes up off the internal stop pin. Curiously, the cutout area of the lockbar doesn't appear to be much thinner than my small Sebenza's. Does anyone know what Ti alloy the handle slabs are made of?
I know it's a light/thin knife and not meant to be a hard-use knife, but there is a fair amount of blade flex, both the vertical flex I just mentioned as well as lateral flex. The lateral flex is probably due to how small the bearings are, and how small a diameter they are arrayed in. I'm definitely going to do what I can to keep this knife in the light-use/slicing category of use. Overall, especially considering the price, it gets a solid thumbs-up from me.
