I like knives, it's fun to get new things and knives don't cost as much as a new gun or bow. My newest knife that I picked up at the shot show is the Piranta by Havalon. This knife is as they say "crazy sharp" becausethe blade is a 60xt scalpel blade, when it gets dull just swap it out. From what I understand a scalpel blade is not a gimmic like others that hold exacto blades, they use quality steel that'll hold an edge much better.

My other new knife is an Outdoor Edge folding caper. This one feels awesome in your hand, you get good blade control with it.
