There are covert knives then there are really covert knives. This is the latter. With that said, don't Google "50-cent knife". You end up with pictures of the rapper 50-cent. This modified real U.S. 50-cent piece has a Japanese steel blade hidden inside. Confusing right, a US coin with a Japanese knife. Don't overthink it. You can get your 5ive Star Gear Covert 50-Cent Knife here.
