A bone broach (2) is formed from a plurality of substantially planar members which are positioned adjacent to each other with each of the substantially planar members attached to at least one other substantially planar member. At least some of the substantially planar members defines at least one cutting profile (4) at its perimeter. The plurality of substantially planar members include a first group of substantially planar members (12a - 12k) defining planes which are substantially parallel to each other, and at least one additional substantially planar member (18a - 18c) defining a plane which is angled relative to the planes defined by the first group of substantially planar members.
