As far as which ones i really like and think that they are cool: katanas, tai chi sword, tonfa, bo staff and jo staff. even though i dont know how to fight with most of those weapons.
as far as carrying one around goes: Tec-9s!
i dont go anywhere without these babies! i make a living off of these two! As soon as i walk up to you with my ski mask on and my tec-9s out, you better have a full wallet 'fo i cap yo a$$ punk!
(joking aside, i would NEVER waste valuable bullets like that!)
