1. A reamer tool apparatus for articular surface replacement comprising:
a one-piece instrument having a shank with a first end and a second end residing between a longitudinal length of the shank;
one or more staged blades residing at the second end of the shank, each staged blade having blade portions for simultaneously countersinking and surface grinding bone of the articular surface in a single step, the first blade portion has a first depth and the second blade portion has a second depth, wherein the first and second depths are in relation to a top surface of the staged double blade, the first depth of the first blade portion is deeper than the second depth of the second blade portion so that the countersinking and surface grinding provides two different depths within the bone.
