Abstract
A hook-shaped knife blade is provided having a curved sharpened inside edge, the sharpened edge comprising a plurality of serrations. The plurality of serrations abut each other to form a plurality of points where adjacent serrations abut, and each serration has an arc-shaped scallop forming a portion of the sharpened edge. The serrations move material away from the leading edge of the blade, thereby keeping the edge cleaner and providing a longer usable blade life. Moreover, the points provide localized pressure on the material when starting a cut, enabling better penetration into the material, while each serration acts as a mini-hook blade, forcing the material to be cut into the curve instead of pushing it away.
