I think the "blade" itself is like a ribbon that responds to a current by curling and extending, and that is where the elasticity, flat edge, and lightning dust come into play... it literally would fail as a weapon without it, there are similar things IRL that use this combination, but I don't think we've really managed to weaponize it IRL due to cost and control issues that can be solved in Remnant by dust and aura respectively
