Abstract
A knife has a cutting blade with an elongate planar body having a front and a back, a first and second opposite edges, the elongate body having a centerline extending between the first and the second edges, each of said first and second edges being provided with a plurality of angularly-oriented notches defined by beveled surfaces, which intersect to form cutting edges. The notches have a generally V-shaped configuration and have one or more sides that extend at an acute angle in relation to the centerline.
Claims19
A knife device, comprising:
- a handle;
- a blade secured to said handle, the blade having a first cutting edge and a second cutting edge, each of said cutting edges being provided with a plurality of notches oriented at an acute angle in relation to a longitudinal axis of the blade, each of said notches being defined by a first side and a second side, and wherein each of said first side and said second side is formed with sharpened surfaces.
A cutting blade for use on a hand held cutting device, the cutting blade comprising an elongate planar body having a front and a back, a first and second opposite edges, the elongate body having a centerline extending between the first and the second edges, each of said first and second edges being provided with a plurality of angularly-oriented notches defined by beveled surfaces, which intersect to form cutting edges.
A method of severing a rope, comprising the steps of:
- providing a knife having a handle and a blade secured to said handle, the blade having a first cutting edge and a second cutting edge, each of said cutting edges being provided with a plurality of notches oriented at an acute angle in relation to a longitudinal axis of the blade, each of said notches being defined by a first side and a second side, each of said first side and said second side being formed with sharpened surfaces;
- engaging the rope with said blade such that strands of the rope enter the notches;
- causing the blade to move against the rope strands, tensioning the rope strands within the notches, and applying a cutting force on the rope.
