The silver-colored pieces are knurling cutters made on a rose engine. They are made from A2 tool steel then hardened to 62 Rc. The brass pieces are samples of the knurl designs. The design on each sample brass piece was cut by the knurl on its left. The knurling cutters are actually full standard size at their 3/4" diameter.
