One knife Crew. Many fish can be cleaned with a smaller knife, believe me. I actually use an electric knife when I have lots to clean. The knife does "not" have to have a #6 grind, although that's better for skinning fish. The #6 grind allows you to lay it flatter for that delicate work. A standard #7 works "almost" as well, but not quite.
One thing for sure: It's a whole lot easier to clean big fish with a small knife than little fish with a big one! You guys figure it out. That's why I gave you a couple of days. Most suggestions have surprised me, so far.
We'll see, Capt. Chris
