  • Patent number: 7243924
    Abstract: An ice skate comprising an ice skate blade holder and an ice skate blade secured in a longitudinal recess of the ice skate blade holder. The ice skate blade has an ice contacting lower and upper curvatures so as to be positionally changeable in one of two alternative working positions with respect to the ice skate blade holder, wherein the ice skate blade is attached. The ice skate blade has also substantially parallel, opposed side surfaces intersected by at least two longitudinally spaced apart apertures coinciding with at least two longitudinally spaced apart, transversal openings in the ice skate blade holder. Use is made of restraining means inserted through at least two longitudinally spaced apart apertures and at least two longitudinally spaced apart, transversal openings, so as secure together the ice skate blade holder and the ice skate blade.
