Abstract: Cutting devices useful for cutting objects or materials are described. Examples of cutting devices useful for creating avulsions in animals, such as human beings, are described. A cutting device includes an elongate main body having proximal and distal ends. A first portion of the main body has a cross-sectional shape that substantially lacks flat surfaces and a second portion of the main body has a cross-sectional shape having one, two or more flat surfaces. The distal end defines a hook having one or more sharpened edges disposed within the notch of the hook. Methods of making cutting devices are also described.
