Abstract
A staged contact, splitting blade assembly for splitting log sections into firewood having specific dimensions. The blade assembly has an entry end and an exit end. The assembly includes radial and bridging splitting blades, arranged in a geometric pattern around a linear axis. Each radial blade has a double tapered, cutting edge, facing the entry end of the assembly, and each bridging blade has a single tapered, cutting edge, facing the entry end of the assembly. Each succeeding blade is offset from the prior blade, such that a log section contacts the splitting blade assembly in the sequence a first blade, a second blade, a third blade, fourth blades, fifth blades, sixth blades and seventh blades. The bridging blades are positioned at a slight angle to the linear axis of the splitting blade assembly.
