The Tribal K karambit fixed blade and folding pocket knives from Fox Knives are the result of a collaboration with Doug Marcaida, knife designer and judge of "Forged in Fire." The design features a blade that's been expertly curved and, on the back, there is a serration that gives a cut similar to that of a saw. The handle is marked with recurring triangular motifs from Philippine Martial Arts. The finger ring provides stability and strength, and the textured handle is designed for a sure and steady grip.
