Hmmm, lets see. A 32in x 8in x 1/8in sheet of what I assume to be Steel for the blade, which comes to roughly 64 square inches give or take some for the curvature(if i did my math right). That would come to just a hair over 18lbs JUST for the blade. That doesn't include the parts for the firearm, the 4 hand grip or the rest of the freaking weapon lol. There's also the problem of the blade having the chance of snapping off due to it not having anything resembling a tang(and you cant say it does, the receiver is in the way ) Any more questions?
