Katana is a great weapon for close encounters, in the version on Steam I used it quite often and I think will fit, but the idea of the sword seems to me strange. At least I think so.
To Snipe34,I searched in internet on swords and I found this one that I thought was a nicer version for kF2.53/3.0. It's a Chinese sword (sabre) that you can include as another sword weapon. Maybe two kinds!?! A nice turdy whack in the head should do the work. Off with their heads! See picture below.
