The ‘Folder’ is a 8 3/4″ long premium aluminum training knife with smooth design and a realistic feel. The authentic micarta handles on this folder size training knife are custom made for the fit you are looking for. The 1/4″ thick aluminum blade is a perfect weight for training because it simulates an actual knife. Because it does not fold and is full-tang aluminum, it’s rigidity is great for practicing disarms and joint locks because it does not bend in an unrealistic way when prying it out of your partner’s tight grip like most rubber training knives. With a lifetime guarantee, this is the best and last training knife you will ever have to buy.
