Gil Hibben is a knife maker well known for designing the knives used in Rambo III and Rambo IV. However, one of his first major contributions to the knife world was the Kenpo knife, a knife now used in the Kenpo long form VIII. A handmade version of this knife was given to both Ed Parker and Elvis Presley, fellow practitioners of Kenpo. The Karate Master is a classic reproduction of the Kenpo knife by United Cutlery which is being brought back due to popularity.
The shape and weight of the blade allow for excellent penetration, and the slant of the hilt allows it to be held with the thumb on pressed against the hilt. This method of holding the knife is much more stable and powerful than the common method, which results in the thumb pointing down.
