Here we have blacksmith guillotines and other blacksmith machines. We have grouped our guillotines with these since they are much more durable than other versions, sometimes called the Blacksmiths helper or guillotine tool, but ours is on steroids. The dies are made of 3/4" x 3" S7 Alloy steel and the base (body) is extra heavy for the constant beating it gets. Is your current model bowed at the bottom from tough dies hitting mild steel. Try our with its hardened base plate for more strength and longer life than the rest.
