Nothing says "American pride" like these wonderful... well I was going to say "weapons", but upon closer inspection, these would all make terrible weapons.
What purpose do these things serve? Are they intended to actually be used, or are they meant to sit in the basement bedroom of a neckbeard who has delusions about fighting people with these shitty blades? Usually, the people who own crap like this think it gives them some sort of authority or ability to fight that they didn't have before. If I had a dollar for every time someone has said "I have this knife if someone breaks in my house" I'd have like sixty four dollars.
Upon more closely inspecting the one on the right, I"m convinced that that is some sort of glass blade. Ok, good luck with that, Mr. Neckbeard defending your house. I'm positive that you'd have better luck striking the assailant with the injection molded eagle handle.
