Replica Knives look like real knives. They are 1" thick w/ a Nylon core. Unbreakable, and firm enough to do disarms. There is 1" of High impact foam at the tip for hard core SAFE thrusting, and 3/8" to 1/2" wide on the edge of the blade.
Great for sparring, and as far as we know nobody has broken any ribs for the last 27 years.
