- Bend to the Bone
Nothing is more important than how a blade flexes, says Neustrom. Flex allows you to work along backbones and over ribs without unintentionally cutting either. Most of the work, he says, is done with the blade's wider half, so you typically want a knife with 15 to 20 percent flex (bend) close to the handle. The tip should flex well, too, because it's used for the more delicate skinning.
