●7inch (ΦID) x 12inch(H) -- split logs up to 6-1/2-inches in diameter because the inner diameter of safety ring is 7inch. Anything bigger needs an axe to depart it first or it will get stuck in the top ring. ●CUT LIKE A BUTTER KNIFE -- the blade is made of HRC30 45# steel with a sharpened edge, solid material with the reverse wedge on the side which means splits wood effectively using less force than a standard axe, made it easier than using an ax or hatchet. ●BUILT LIKE A TANK -- the main body is made of rock-solid carbon steel with a paint-coated rust-resistance surface, one piece welded with no screws to come loose. With the ring guard design, the hammer never hits the blade or your feet and keeps things contained safely so pieces parts dont fly off flying into your shins. ●WEIGHT OF 9lb MAKES IT STABLE -- never worried about tipping over, it weighs up to 9 pounds. But we still recommend mounting it on a solid surface thats why it comes with bolt holes for permanent mounting. ●4lb 45# STEEL HAMMER -- hardened, drop-forged steel head attached to a steel handle with a non-slip cushion grip for comfort. works really well pushing the log down the middle which act as the pivot that does the splitting.
