Abstract
An ice skate assembly for attachment to a boot has a skate blade and a blade heating arrangement mounted within a blade support. The blade is heated by a row of field-effect transistors carried on a circuit board or another type of heating element encapsulated on the top edge of the blade in an over-molded plastic strip which engages into a slot in the support as a wedged fit. The blade is attached by an inclined wedge member a screw for pulling the blade longitudinally of the blade and to draw the inclined wedge member into its receptacle. The battery pack is carried in the rear tower which is sealed against moisture penetration and includes two proximity switches for actuation.
