Let's see, in 4e, one of my characters routinely carried: a katana (Weapon focus), a sword (wakizashi), twin vibroblade swords, twin Cougar Fineblade Long Blades, a Combat Knife, a Survival knife, Victorinox Memory Blade, and two pistols (either Yamaha Sakura Fubukis or Nemesis Arms Praetorians, one loaded with EXEX, the other with SnS). Also had a sword cane, for fancy shindigs, twin forearm snap-blades, and when he was really expecting trouble, a set of six Flashbang and six Thermal Smoke grenades. The Flashbangs he typically tossed blindly around a corner or into an enclosed space, while the thermal smoke he would drop at his feet and use an Ultrasound or ultrawideband radar sensor, or switch to astral sight.
