This is the ORIGINAL OSBORNE 84 SPLITTING MACHINE. Cast iron frame. Made from the original Newark, NJ pattern. Uses a movable twist handle to set blade depth. A locking stop can also be set to return to the same setting. The operator inserts a strap, pushes the handle forward and twist to lock in position. When pulling leather through, the operator continues to advance the handle forward with the free hand to create a tapered skive. Has a brass round bar across the blade as a safety feature. 8" hollow ground inlaid blade. Instructions sheet provided. Replacement parts available by special order.
