Well......... in the freshwater fishing that I do in the Midwest my fishing knife needs are simple but require 3 differanr knives.
Knife # 1 , I always have my EDC pocket knife, a Barlow,Stockman,Sod buster,Bucklite,... doesn't matter, what ever is in the pocket. Used mostly for cutting up apples for lunch, opening new lure packages, carving points on sticks, cleaning the fingernails or any of the many things one does with a pocket knife, fishing or not.
Knife # 2 is in my tackle box or bag,(I have several so they get spread around). It's a SAK with scissors.
used for cutting braid line mostly. The other tools and blades on the SAK's get little use but I take comfort knowing they are there.
knife #3, Fillet knife for cleaning the catch if i'm killing fish. My favorites are my 6" Western's, unless I'm dealing with Big Salmon or Big Cats, then I have a Chicago Cutlery 66s slicer with a stiffer 8" blade that is great for making steaks out of the big boys. Most fish cleaning for me is done at home and thats usually where these knives are kept
When saltwater fishing, I used to have a bait knife in my gear for cutting up bait fish, a stainless steel Mora with a 4-5" blade was usually chosen. These seemed to go missing fairly often so nothing expensive for me. Maybe if I had worn a sheath I would not have lost them.
I never wear a knife while fishing, comfort and weight I guess is the reason.
I would like to find a slightly shorter fillet knife that I liked to be used for Bluegills and Redears, I don't catch then so large that I need the 6" blade to skin the fillets and a 4"-5" blade would give me more control and better speed I think when filleting a mess of panfish. or I could just do the skinning with the 6" knife and the cutting with a shorter knife.
They are very popular, and I recomend them to guys who crappie or white bass fish a lot... but I think that for ME Electric Fillet Knives are an abomination and are an invention of the Devil. Maybe because I rarely have more than 15 or 20 fish to clean at a time.
all this said I would like a Randall Fisherman. ???? or a JK improvement of it!
