This "No Bones About It" knife bills itself as "the world's greatest fillet knife." While I won't go that far, I will certainly say it is the most versatile. It works equally well on small panfish and big northerns, and doesn't need to be sharpened as often as a lot of knives I've used.

When I fish Kentucky Lake, I put crappie on ice for a day before cleaning them. This knife has no problems slicing right to the bone -- day after day -- on these partially-frozen fish, and helps get every last bit of meat off of a fish. Highly, highly recommended.
