Apparatus and method for harvesting bone

An instrument for bone grafting and/or shaping bone, comprising:

• an elongate body having a proximal end and a distal end;
• the body serving as a handle for the instrument, and supporting a cutting blade of a ring-like shape.

An instrument for bone grafting and/or shaping bone, comprising:

• an elongate body having a distal end and distal end;
• the body serving as a handle for the instrument, and supporting a blade assembly therein;
• the blade assembly having a cutting surface and an area of reduced mechanical strength displaced from the cutting surface, the area of reduced mechanical strength allowing the cutting surface to be angularly positioned relative to a longitudinal axis of the blade assembly.

An instrument for bone grafting and/or shaping bone, comprising:

• an elongate handle having a proximal end and a distal end, and supporting a blade assembly therein;
• the blade assembly having a first end adjacent the distal end of the handle and separated from a proximal end by a body portion, the body portion having a longitudinal axis, the blade assembly coupleable to the handle to reduce the flexibility of the blade assembly, the distal end of the blade assembly having a cutting surface, the body portion having an area of reduced mechanical strength disposed between the distal end and the proximal end to allow the cutting surface to be oriented at a plurality of angles relative to the longitudinal axis.
