Snow oar for manually clearing snow and ice

An implement for manually clearing snow and the like, said implement comprising:

• an elongated handle comprising an upper end and a lower end, the handle defining a handle length direction along its elongation axis;
• a blade having:
• a blade height direction oriented upwardly and downwardly between an upper edge and a lower edge of said blade,
• a front face and a back face, said front face and said back face bounded upwardly and downwardly by the lower edge and by the upper edge, said front face being, in an absence of a load, arcuately curved in said blade height direction between said upper edge and said lower edge so that said front face is concave,
• a blade width direction running substantially transverse to said blade height direction and substantially parallel to said front face of said blade;
• a first side edge and a second side edge,
• handle attachment means to secure said lower end of said handle to said blade proximate to a trailing edge of said blade and centrally in the blade width direction, whereby said handle thereby extends upwardly and away from said blade in a direction substantially parallel to said blade height direction,
• a blade height defined as a maximum extent of said blade between said upper edge and said lower edge in said blade height direction,
• a blade width defined as a maximum extent of said blade between said first side edge and second side edge in said blade width direction, and
• a blade depth of curvature defined as a maximum depth of the curvature of a front surface of said blade;
• wherein said lower end of said elongated handle is attached to said blade with said handle attachment means;
• wherein a handle length is defined as the length of the attached elongated handle measured from said upper edge of said blade to a furthest extent of said upper end of said handle;
• wherein said handle length is in the range from about 1,397 to 1,900 mm;
• wherein said blade height is in the range from about 254 to 318 mm;
• wherein said blade width is in the range from about 101 to 242 mm;
• and
• wherein said blade depth of curvature is in the range from about 12 to 38 mm.
