How we chose the best flexible fillet knives

• Thin, tapered blade that bends without kinking
• Edge that skins cleanly
• Grip that stays put when wet

Flex lets the blade ride over bones instead of cutting through them. Too much flex on big fish feels whippy, so match flex to fish size.

A flexible fillet knife also doubles as a fish skinning knife: the blade bends flat against the skin to leave less meat behind.
