An annular cutting tool and related methods are provided for herein that exhibit improved durability, cutting performance, and/or reduced heat generation for bone graft resections. The annular cutting tool can include an annular body having cutting teeth with a flat, flared distal tip for greater durability. An extended gullet can be disposed between groups of adjacent cutting teeth to improve removal of bone debris away from the cutting teeth more and thus prevent binding during use. The annular cutting body can have a recessed surface portion to reduce the area of direct contact to bone and thus reduce heat generated. The recessed surface portion can also provide an area in which bone debris can accumulate away from the cutting teeth to prevent or reduce binding of the tool during use. The annular cutting body can also include a drill bit for drilling a hole in a resected bone graft.

A bone saw cutting guide block includes a body and a bone saw guide assembly. The body includes a proximal surface and a distal surface. The bone saw guide assembly includes a first guide slot defined by the body. The first guide slot extends through the proximal surface and the distal surface along an insertion and retraction path. The first guide slot may accommodate lateral movement of a bone saw while guiding the bone saw along the insertion and retraction path. The first guide slot includes a first interior surface and a second interior surface. The first interior surface is spaced a first distance transversely away from the insertion and retraction path. The second interior surface is spaced a second distance transversely away from the insertion and retraction path. The first distance is smaller than the second distance.
