Crutchtip - Interesting point. For clarity, I won't be filleting fish with it but I'd be shocked if it couldn't gut one. For 20 years that I dove and speared fish, a US divers knife and later a Wenoka knife worked just fine. Both were double hilt, were 7 and 6 inches respectively but they each did have a more pronounced point. They also were just 3/16" not 1/4" but gutting a fish is a pretty course process. Are you suggesting the Divers version is more appropriate?
If you want to gut and/or clean fish, get a knife(s) by Forschner or maybe Dexter-Russell designed to to so. The #16 is a dive knife made for cutting, prying,and a more utliltarian role. Could it gut a fish? Sure, it could to allot of things, but if I am going fishing I am gonna have the proper knives with me.
The 16SF has always been a bastard to me, a solution to a problem that didn't exist. If you want a double hilt, just get a #16 with a double hilt. The finger relief on top of the 16SF blade is all but useless except perhaps on the BP handle, but in any configuration it is not an attractive knife.
