When we had a development discussion during IVANcon, the idea was brought up and Kahvi explicitly stated that it was something that was planned, but not implemented. Therefore, I am not sure that the weapon info attached to it is something that is actually in-game, or just planned.
If you happen to come across both electricity resistance and lightning hammers early on it can be pretty good. They're pretty quick compared to maces and can block better too, so if you get some skill early on they're better than Turox in some regards. They become much more useful in the longer corridors and open spaces of GC than they are in UT where they don't really get to bounce back at you.
