    Abstract: A two sided pruning saw blade includes a main blade body, a concave underside cutting edge, a convex over-side cutting edge, and optionally a claw-shaped hook. The convex cutting edge is formed along a top edge of the main blade body for under-cutting a branch to form an underside kerf therein. The hook is positioned adjacent to the underside kerf to align the main blade body on a top side of the branch with the underside kerf. The concave cutting edge is formed along a bottom edge of the main blade body for over-cutting the branch to form an over-side kerf and to subsequently connect the over-side kerf with the underside kerf to sever the branch. The claw-shaped hook is disposed distally relative to the underside cutting edge to prevent the main blade body from passing wholly through the over-side kerf during cutting thereof.
