I use a vintage Normark (which I think Rapala bought out) folding fillet knife for cutting cheese and apples and I love it. I do not use it to fillet fish as I have better knifes to fillet fish with. It is a nice knife, but there are better knifes for fish, IMO.
I take one to the Bdub. When folded(not in use) I can't cut myself!!!!! The sheath filey knives can slip out of the sheaths. It is a typical Rapala knife, can get really sharp, dulls after 4 or 5 fish. I take one of those little 2 stage ceramic things...not as good as home, but it works for a trip.

Yes, agreed, I've been taking one for years. Not because it holds an edge though. I take it because it is convenient, fold up, good grip. I have to sharpen it before about every two to three fish. I'd say it is a good buy for a week or two a year. But get something else good for home.
