I have a Schrade and I love it. Good flexible blade and it is easy to sharpen. I usually put it on steel for 6 or so strokes prior to sharpening and it holds through 15-20 fish and then I hit it again. I like a very sharp edge and believe in maintaining that edge.

I have a back up knife that is made by RADA. I bought it from a friend at work because his daughter was selling RADA products as a fund raiser for school. I think it was $18 and that is a pretty decent knife.

For a back up, to those 2, I do have a CASE filet knife. the blade is pretty stiff but as CASE products go, it will hold the edge.

Comparing my fileting with a manual to an electric, my dad and I both started with 30 crappie each. I'm a stickler about saving the rib meat so I do take a little time with my fish. Dad cuts through the rib cage with the electric knife and then has to cut the rib cage out. He finished 1 fish ahead of me. Manual fileting is my choice.
