I was in Wade's Gun Shop here in Bellevue the other day looking at handguns and I ended up walking out with a Chris Reeve Umnumzaan. (Oops.)
Thing is rock solid, incredibly smooth, and definitely the nicest knife I've had the chance to play with. The lock is very positive, there is absolutely zero play in the blade, and it actually does open very quietly which I appreciate. Obviously if you really flick it hard it does make a clicking noise, but it's totally possible to open it up fairly quickly and have it lock without making much noise at all, which I consider to be a useful feature.
