Badassness is now easier than ever before! It chops ok, but you can put all your weight behind a thrust. it uses an $8 survival knife from harbor freight and some pvc. the 3/4" pvc fits perfectly into the hollow handle of the knife. the rest is a "T" part used as a handle, and a piece large enough to act ac a brace around the arm. see pic. 2 for build info.
P.S. By the way i have an enfield bayonet (see pic), and i'd like to make one of these with a bayonet lug attachment so it's useable as a sword and this.
