ABSTRACT OF THE DISCLOSURE An ice-skate sharpener comprising a stationary electric motor grinder including a diamond bit carried by an arm pivoted on a support adjacent the grinding wheel to the desired transverse curvature, so that and ice-skate blade can be sharpened with the desired hollow ground. The sharpener further includes a pair of self-centering jaws to clamp the blade of an ice-skate therebet- tween and pivotally connected to the cuter end of articulated arms, themselves pivotally mounted on a support secured to the work bench bench of the sharpening assembly. The level of these arms can be adjusted t bring ice-skate blade carried by the jaws in exact alignment with the pivot of the arm supporting the diamond bit, so as to produce a hollow ground, which is exactly centered with respect to the side faces of the ice hockey blade. The jaws are self-centering so that the centered hollow ground is obtained independently of the thickness of the ice hockey blade. The sup- port carrying the jaws is further insulated against vibration, so that perfect grinding of the ice-skate blade is obtained.
