1. A blade used for cutting corrugated sheets comprising:
- a blade unit including a planar blade shank portion defining a plane, a first transition point where the blade unit bends out of the plane to form a first cutting edge (35) and a second transition portion where the blade unit bends out of plane and is embedded in a discrete first guide member;
a third transition point where the blade unit bends out of plane to form a second cutting edge at an angle diverse from the blade shank portion and the first cutting edge;
said first elongated guide member (33) partially encasing the blade unit below the first cutting edge and extending to both lateral sides and in front of the first cutting edge of the blade unit;
a second elongated guide member partially encasing the blade unit below the second cutting edge and extending to both lateral sides and in front of the second cutting edge of the blade unit;
the first and second guide members having top and bottom surfaces perpendicular to the plane of the planar blade shank portion so that the first and second cutting edges of the blade shank are angled to create beveled cuts when the blade is drawn through a corrugated sheet.

Abstract
A blade shank that can be used for cutting corrugated sheets incorporating improvements to blade design and cutting geometries for an improved cutting action on corrugated sheets; that may include a handle, but does include a blade shank or blade base, at least one cutting edge, at least one guide member attached to the blade base or blade shank; the blade shank can be attached to a handle with the cutting edge facing rearward while the guide member is directed rearward wile the guide member straddles the cutting edge or edges.
