A method for making an acetabular reamer for an acetabular reamer comprising the steps of: fabricating a bowl shaped cup-blank having outer and inner bowl shaped surfaces, perforating a plurality of holes through the cup-blank, the holes each are surrounded by a curved margin, deforming outwardly of the outer surface a cutting portion of the margin of each of the holes, thereby forming cutting edges, the cutting portions are curved outwardly of the outer surface, the cutting edges are curved tangentially of the outer surface and disposed to cut upon rotation of the acetabular reamer.
