The knife (1) has a partial circular plane mounting section (2) placed around an axis (X-X) for mounting the knife. A corrugated blade (6) has an outward curved blade (7) and an inward curved rear blade (12), where thickness of the blades reduces towards outward. The blades (7, 12) have grinds (8, 9) that lie on same side (11) of the corrugated blade. The size of the corrugated blade is reduced by a bevel (15), which runs on another side of the corrugated blade. A transition region continuously crosses both side surfaces of the corrugated blade. |
