It actually kind of works
Plastic, even "grivory", is not great for cutting edges, but this fairly hard material works for thrusting. It does not stack up to metal blades, of course, but does put a pretty good hole in soft targets like cardboard, fruit, and meat. CS claims they made this in order to have a weatherproof knife, but obviously could be used more nefariously. Interesting last resort for personal defense.
