In Shadowrun (the actual table top, not that FPS... thing), my street samurai's named most of his weapons, and will name every piece of hardware he plans on keeping.
Right now, his favorites are Sleepy (A desert eagle like handgun that's loaded with nothing but tranq darts ever), Stalker (an M16 with a lot of recoil compensation, a scope and silencer... and M203), and Jack and Daniel (Pair of matching .44 Magnum Revolvers).
But for swords...
