Because it is the only muscle powered, one man operable, portable crossbow I know off that can shoot a massive 1lb wooden rod (30mm x 1000mm) through 4 cm of massive oak - with no tip, just 100% blunt. It wasn't operable due to some minor damages (paracord was worn out, trigger broke off). Had to repair it for another German TV team that wants to film this Thursday. Shot it, for the first time ever in warmer weather! Unbelievable. It shot the unsharpened, plain rod right through my massive oak panel... leaving a perfectly round hole behind. Massive splintering of course. See the part where the face of the rod hit? Shot from 10 meters.
