The Messermeister 12" Fillet Flexible Knife has a long, thin, and extremely flexible blade that cuts extremely close to a spine, bone or other hard surfaces. The alternating kullenschliffs (a.k.a. hollows or grantons) on each side of the knife reduce drag and prevent items from sticking to the blade. This non-stick fillet knife makes cutting, and slicing fragile foods a piece of cake. You can even get a precise cut on a cake with this knife if you wanted to. That's how precise the blade is.
