Disclosed is an improved snow shovel having a graphite in-laid polyethylene blade with outwardly propagating reinforced ribs providing a flex resistant blade of minimal thickness. A shaft of the shovel is constructed of a low cost steel pipe covered with a polyethylene sleeve with knurled grip surfaces. The sleeve conforms to the pipe diameter upon application of heat during manufacture. A one-piece handle is attached to the free end the shaft. For storage purposes a cutout is provided on a top edge of each shovel allowing nesting of similarly shaped shovels. A straight blade shovel and a pusher type shovel are two embodiments disclosed herein.
