I know where you are comming from Bunni. That hammer from 64' is a good because it was properly forged. I'm sure there are plenty of great old tools out there that function very well, toss on a good handle, and it's good to go.
I know a CS Tomahawk can do the same chores that a much more expensive hawk can do. The big difference, to get a properly made, heat treated, properly ground and sharpened, and good haft, and maybe a useable sheath on a new forged hawk, well that's gonna cost at least $100. Think about the maker's labor, materials, tools, forge, shop, and the sheath, all that costs money, in today's market none the less.
After you train with a certain weapon, and get to try many types, you can understand what elements make one better. One aspect is in the feel, weight, balance, mass distribution, and the handle design/length. Another aspect is the geometry of the weapon, how it's design actually performs the tasks it was intended for, how well does it cut, puncture, or destroy. Handling is extremly important, how well it swings, changes directon, or stops can affect the outcome of a fight.
Maybe, for most people, there is an element of fantasy in the context of fighting, say after the PAW. Martial arts have been practiced during war and peace, for a long time, and will be for a long time to come.
Tomahawks are both tools and weapons(most of them) and when camping, a very important one at that. If your hammer breaks on the job, you can borrow, or go buy a new one. Most of us will not just find another forged hawk head in the forest, if you do take it home and fix it up.
