Having seen an episode of Pawn Stars, I realised that at the time the US Joined WW1 they manufactured some brutal melee weapons in the form of a
triangular blade with basically a knuckle-duster with knub end, to club, punch then stab(the triangular blade to pierce the German Trenchcoat).
Another by Aulion, the same "duster" designed grip, but a fearsome sharp blade (stiletto type).
As for Light Sabre's, the Large Hadron Collider at C.E.R.N. is making headway on Anti-matter which "annihilates" on contact with matter, so, a
containment field around AM to destruct on contact with matter (body parts) would cause a mini big bang destroying all matter and anti-matter in
contact.
So the fantasy about melee weapons may be short lived, but having been a serving soldier, the further from "Fix Bayonets" the engagment the better
in many cases. (FIBUA/FISH excluded).
My advice is stick to hypotheses and dont join up, as, if you relish "melee" its safer done on the X-box than coming away with "Survivor guilt"
and seeing your friends&"family" sometimes fatally wounded.
War isnt a HALO game, it's for keeps.
I know it was a hypothetical question, but with a Physics interest I thought I might indulge/humour you with an answer you can research.
Hope it helped somewhat.
