The "Evis-1" is a collaboration between Mantis and the USMC.
Adam Chavez came back from Iraq with an idea for a perfect karambit. We sat down and sketched out his ideas...what we came up with is what you see here today, right down to the price tag, Adam was involved during the entire process, and he was rewarded for his efforts by receiving instant celebrity status at our forum, but also he now carries the #1 serialized Evis-1 on his belt...but he doesn't have to carry it there...the Mantis Infini-Clip allows you to carry it virtually anywhere on the body.
