Yo! Capt North here after a bit of a time away in la-la-land dreaming up new and weird ways to do things.. Lately been getting into 40k and gotta say, I like the idea of a chain sword.. that and been playing Gears of War and love the Lancer. This has brought me an idea for a cyber arm weapon mod that could be useful in more ways then one.
The idea is basicly a small chain saw blade hidden inside the arm between the wrist and elbow on the outside of the arm along the bone, when retracted it looks normal and fine, activated the cutting side of the blade pops out just enough to give it some cutting space (about an inch or so from the arm) while the rest remains hidden in the arm. I'm not sure how stats would work out or such.. but some basi ideas.. like say someone has some cuffs or such on you, with strong enough blades it could be possible to cut them off (though might draw some attention) the obvious melee applications, or even just being able to get through some doors and barriers easier.
Things that would make it impratical would be how dirty the blades get enless there was some sort of cleaning mechanism inside the arm to help with that. Biggest problem would be the chain breaking while moving either damaging the arm or hitting whom or whatever. something very not good as many loggers and such can attest.
Not a very subtle weapon, but if used properly could be a fairly effective one, hidden right it could look like little more then some weird parts in a cyber arm (or leg if someone wanted to get it between the ankle and knee) another peice of hidden equipment for when could be useful, a good tool for when one needs to get a door or such down quickly, or other such.
Any ideas on the stats, pratical, impratical, or other wise?
