ABSTRACT:
A gauge is disclosed for measuring squareness of a skate blade that has a pair of parallel side walls and a pair of bottom blade edges. The gauge includes a squaring frame that has a vertical blade contact surface fixed to a gauge plate. The gauge plate has a horizontal top surface. The vertical blade contact surface is selectively fixed to one of the side walls of the blade with a magnet having at least two parallel faces. Such a magnet is fixable between the skate blade and the blade contact surface. The gauge further includes a blade angle indicator having a flat lower surface and a parallel flat upper surface. Preferably the squaring frame of the gauge further includes an oblong vertical pivot aperture therein and the blade angle indicator includes an aperture therein, such that the squaring frame and the blade angle indicator may be pivotally fixed to each other with a pivot means.
