The XM-24, taking the tough as nails XM-18 and putting it on steroids! Everything about this workhorse breathes hard use knife! I continued with the same overbuilt blade,handles,hardwear and attention to detail and quality build that is the XM series of folders and beefed it up for the XM-24! Check out the specs on this beast and then get one in your hand, you will agree that a overbuilt large folding knife does not have the be uncomfortable to use!
