I usually try to read up before asking but I'm not finding much on the making of a Salmon Fillet knife. I've been using 440c lately and want to stay with same but looking for advice on taper, curvature, thickness/flex. Mostly cutting tail to head fillets. It's for a friend so I could use some advise from someone that uses one as to what characteristics might make it enjoyable to use. Thanks for your info and time. JamesganginAlaska
