I don't carry a firearm, or a knife at this point (although I would like some kind of a pocket knife, more to deal with terrain than anything). For those who don't want to carry a firearm, like myself, I highly recommend always bringing a geo-pal and telling someone else that you are going out. Plus, bring a cell phone if possible or if you are in a wilderness area and cell phone service is not an option, some places you can rent satellite phones to reach park rangers/wilderness rescuers etc.
