[@Unknown100] It's not unheard of for multiple people to know self-defense. And as for the weapon, everyone has a style. It's technically not any different to multiple people carrying knives. Just people tend to see specific swords themselves as more unlikely to see out in the world. In reality, if the zombie apocalypse happened, people would gravitate to the weapons they think would be best. So, if they came across them they'd probably bring it along. Swords aren't as rare as people tend to think they are. And my guy is decent at best in self-defense. Anyone else trained to fight any would likely still beat him hand-to-hand.
