These black polymer hard plastic knives are made of the same material that Glock pistols are made from. They contain no magnetic material, so they are undetectable through metal detectors. This can also be a great Polymer Letter Opener.
We also sell Joker Knife, Hidden Comb Knife and Butterfly Knife for serious Knives Collectors.
We also sell 1918 style Trench Knife (with Brass Knuckles!).
