It only works if you have two of them. Haven't you seen any Resident evil movies?

I want to put my 2 cents in and agree with AROTC on a couple of points his post made me aware of. I'd consider a kukri more dangerous than an axe or hatchet simply because there's more blade to go around and if swung properly, an axe with a long enough handle is no real risk even if it glances...I also think it's harder to swing a kukri properly than an axe. I also agree that an axe would be easier to sharpen in the field. No recurve and there's less blade to have to get sharp.
