Got a Real-World Weapon, Armour or Tactics Question? Mk. XXVIII

[Maquise]

That would depend entirely on the design of the prosthetic. Ideally the blade would be integrated into any appropriately sized void in the arm.

Indeed, but I was wondering how it would be designed to be used. Would arm-blades like we see in Cyberpunk or Deus Ex be the best way to go about such a weapon, and if so what configuration would be optimal?
