The Candiru fish are vicious little fish that are known to enter the human body via the urethra or other “orifices”. In 1997 a victim alleged that a Candiru jumped from the water into his urethra as he was urinating in thigh deep water in Brazil. The Candiru knife is a sweet little fixed blade from the guys over at ESEE knives. Made from high carbon 1095 steel with an overall length of 5.13″. It features a skeletonized handle that can be wrapped with paracord or you can pick up some scales that are sold separately.
