Novel tempered rust resistant steel wheels for installation on conventional in-line four wheel roller skates, parallel four wheel roller skates, and, in-line five wheel roller skates that convert traditional ground roller skates into ice skates. The novel wheels can have different diameters, thicknesses and varying concave edges. The diameters and sizes of the tempered rust resistant steel wheels must be the same as the roller skates' composition or rubber type wheels, except for the thickness of the wheels can be 1/4 inch, 3/16 inch for in-line skates and 1/4 to 1/2 inches for a parallel wheel roller skate. The heights of the sharpened concave edges for the steel wheels can be approximately 30/1000" to approximately 40/1000". Optional scraper bars can be used. The wheels can be used for making ice skates used for figure, dance, pair, freestyle, and recreational skating. An mathematical algorithm and equations are disclosed that determines the desired convex edge dimensions on a cutting bit that conforms to a concave edge on the wheel using a selected wheel thickness and concave curvature edge heights.
