ABSTRACT:
A snow shoe (1) has a longitudinal support structure or ridge (18) surrounded by a screen (4). The longitudinal ridge defines a plurality of apertures (180a, 180b, 180c), an upper surface (20), and lower projecting surfaces (21a, 21b, 25a, 25b). A detachable blade or knife (30) includes a central projection (33) which extends through the aperture in the central ridge and mates with portions of the lower ridge which define the aperture. The blade includes a rearward extending tab (330a) which extends through the aperture and engages the upper wall of the central ridge. A rivet or other pivot pin (34) pivotally holds a bar (35) to the upper projection of the blade. When the upper projection is received in the aperture, the bar pivots to engage the upper surface of the central ridge. A plurality of knives or teeth (36a, 36b, 36c, 36d, 37a, 37b, 37c, 37d) extend downward to engage ice or packed snow.
