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 and serving to dress the peripheral face of the grinding wheel to the desired transverse curvature, so that an 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 therebetween and pivotally connected to the cuter end of articulated arms, themselves pivotally mounted on a support secured to the work bench of the sharpening assembly. The level of these arms can be adjusted to ring 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 support carrying the jaws is further insulated against vibration, so that perfect grinding of the ice-skate blade is obtained.
