There used to be a lot of interest in slipjoints around here but I haven't seen much lately. I just picked up a couple new ones that I'm pretty excited about. Made by Great Eastern Cutlery. Good walk and talk, nice fit and finish. No wobble in the blades. 1095 carbon steel and I've convexed the blades on one of them (two-bladed Scout) and they appear to be well heat treated. Some models also come in 440C but I haven't tried any of those yet.

Any slippie fans still lurking around here?
