Abstract
A single blade ice skate is disclosed wherein the ice engaging blade, the toe boot plate and the heel boot plate are formed as a unitary assembly from a flat sheet of metal stock material, with the two boot plates being attached to the blade by way of twisted metal extension portions. In the initial flat state, the blade portion, the two extension portions and the two boot plates occupy a common physical plane. The two extension portions that connect the boot plates to the blade are then twisted 90.degree. in this common plane, and in a manner to place the two boot plates in planes that are normal to the plane of the blade and normal to the common plane of the initial metal stock material. The two boot plates are then bent into a U-shape, so as to provide a U-shaped vertical spring member for each of the boot plates, the spring member acting between the two boot plates and the blade (i.e. a spring member operating in the vertical plane of the blade), while at the same time providing a rigid lateral connection between the plane of the two boot plates and the plane of the blade, thereby rigidly maintaining these planes as normal planes during a skating maneuver.
