Without a firearm, I have several things I think COULD work. I have my Cold Steel Heavy Terrain Chopper, with a 15 inch blade. It was a limited production item. I also have other knives from Glock field to Cold Steel OSS to even a Machete from Colombia that is very impressive.
In the club division, I have my wooden Louisville SLugger I've hade for 35 years now still in excellent shape. I also have a new handle in my pick that I'd take out in a moment and it would be a fine club.
if I had to plan on a weapon for hand to hand, I'd look for a good spear, and a small sword ot large knife with a tanto type blade and have it razor sharp. I'd also stay in a high position with a pile of bricks to throw, and make Molotov Cocktails.
Your strongest weapon is your mind...
