Abstract

A fingerling shear for shearing a length of wood in a plane transverse to the grain direction and for splitting the sheared length along the grain direction to form a plurality of fingerlings. The shear includes a planar shearing blade, supported for rotation about a generally vertical axis, the planar shearing blade including an involute cutting edge adapted to engage the elongated piece of wood during rotation of the blade and for shearing off a length of that piece of wood, and a plurality of splitting blades fixed to the lower surface of the planar shearing blade and spaced along the involute cutting edge, the splitting blades each including a leading cutting edge spaced from the involute cutting edge of the planar blade and extending tranversely to the lower surface, the cutting edges of the splitting blades being adapted to sequentially engage portions of the sheared length of the wood stock to sequentially split fingerlings from the sheared length.
