Abstract
A cutting tool (20) is disclosed which includes an integrally secured arcuate cutting blade portion (32). The arcuate blade portion is defined from a loci of a perfect circle and includes an axially elongated arcuate blade portion (38) and an axially recessed arcuate blade portion (40). The axial length of the recessed portion is equal to that of an adjacent planar blade portion (42). This configuration permits the elongated arcuate blade portion to be retained within a first distinct cut of the material to be worked on or bone being cut while the entire tool is rotated to a distinct second position along the upper surface of the material in order to perform a distinct second cut. These two distinct cuts serve to form a removable section (58) of the material being worked upon or bone cut, and in this manner adjacent sections of the material can be repositioned relative to one another once the second cut is performed and the section is removed. The rotational repositioning of the cutting tool along the surface of the material being worked upon is facilitated by the relationship between the recessed blade portions and the axially elongated arcuate portion, and various indicating devi…
