Abstract: A method and apparatus for removing fat from one face of a meat cut, where a knife tool cuts a layer of fat and possibly skin from the face. The knife tool is adapted to cut across the entire width of said meat cut along a desired trimming interface. The knife tool includes at least two controllable blade parts, each having a cutting edge, the blade parts extending between the first face and a fat-to-lean interface without intersecting said first face. The position of said cutting edges and the angle of the blade parts are continuously adapted, by controlling the at least two controllable blade parts, to cut following the desired trimming interface, whereby the fat and possible skin is trimmed from the lean in one single piece of fat.
