I have been carrying the Mantis MK-3 Karambit for sometime now. I carry a knife for self defense purposes and a while back, decided to learn to use a Karambit. Its principals are not based on strength, but the ergonomics of the blade itself. After looking around for a good, yet affordable Karambit, I came across the Mantis knife company. I like many of their knives for the design and possible uses. So I chose the MK-3. Great, lightweight and really sharp. It fit perfectly in my hand. I am looking at the Chaos Folder now. Nice modern lines and wicked looking. Give them a look! Reasonable prices too.
