I am curious about the Kel-Tec folding bayonet. It may be the first of its kind in the world. It's only available directly from Kel-Tec's on-line store and well, pricing is about USD$150 a piece.
From the looks of it, this knife can take some serious beating and its construction seems rugged. I love the polymer handles and blade geometry.
The business end of this knife is only meant for one thing - a bayonet charge. Which rarely happens these days. Well, usually very close quarter. So, when you are out of ammo, the last ditched weapon is to mount bayonet on the muzzle of your assault rifle.
Well, someday if I see this baby surfacing on ebay or some aftermarket trading forums, I might give it a shot...
