Recently I've been looking around for a new dedicated outdoorsy knife. (Mostly because I can't keep my bm 200 puukko from rusting out on hiking trails lol.) My first choice was the Sprig because it's BEAUTIFUL but s90 is a wee bit rust-ish so Waterway it is. But one thing about it weirds me out. The big unsharpened chunk at the base of the blade. So, why? Is there a point? it doesn't look big enough to choke up on the blade without slicing my fingers off, and it takes a quarter inch off of the blade length. Does slicing up fish require extra skin bludgeoning that I was not aware of?
