Im the UK these are the best options I can think of;
Brassknuckles for a weapon that you can use without making it too obvious your using a weapon so any onlookers would see it as not as bad as it is
(apart from the noise on bone!)
I love Halberds long spear, axe head and armour peircing hook all in one. But thats guna be cumbersome.
Probably a good large knife like a bowie as well as a smaller stabbing one with a thin profile like the loverley fairbern sykes fighting knife which
would give huge penetrating ability. Or even better the cold steel Tai Pan I think it is is a wicked dagger. Thats your best bet to peirce armour in a
knife I think.
A good axe is also a great tool so having one of them would be good.
Obviously depends if your on the move or staying put. A claymore certainly would be intimidating tho!
I have got myself a Panga Machete, it is very Great, very light but strong, super sharp, with a sheath. Its ready in my room, For when the # Hits the
Fan! It will happen oneday, this Planet is in a right mess, I've got the tools to Survive.
If anyone is thinking about getting one and not too shure, get one you wont be disappointed.
I with my Panga Machete have a Spike Tomahwak again its Very strong a super sharp, even im scared of it, even when I've got it in my hand, It has a
deadly Spike on the side which goes through most things, and if not it leaves a dent.
