Picked up an Esse (SP)? Avispa and not very impressed by it at all. I know they are not made by Esse but the knife is new and hard to get open plus the edges are a bit sharp on the frame lock. I guess maybe in time I'll get to like but as of first impressions not good at all, I did pick up a Rat Model 2 and just like the Model 1 it's way much nicer in my opinion.
