Out of curiosity, just how much blacksmithing do you do?
I do a decent bit of metal working.
There are a couple of ways to make a long, straight, edged weapon, which for convenience we're going to call a sword.
The one most people are familiar with is buy blacksmithy or forge work. In this method a blacksmith heats a piece of steel until it is at workable temperature then uses a hammer, anvil, and various other tools to shape it into a shape that you would recognize as a 'sword'. The weapon is then finished by having a handle and guard affixed. The surface of the weapon is polished with various stones and files, and the edge is sharpened.
The second method of making a sword is by a process called Stock Removal. In stock removal the bladesmith begins with a piece of iron or steel that is roughly the right size. A common source of high quality steel is the leaf springs used in vehicles. A single car may have as many as a dozen leaf springs, each of which is a bar of very, very high quality steel.
The bladesmith shapes the blade without heating it at all using a variety of hand files. Power tools may be used if they are available. And, in desperate situations, it is possible to grind a blade using a piece of concrete or rock. I have personally witnessed someone grind a razor edge into an old garden tool with a piece of concrete and proceed to shave hairs with it.
Having shaped the blade, the bladesmith is now ready to finish the blade. Since the steel used was manufactured to the very highest standards it is already of very high quality and requires no further finishing. The bladesmith can affix a handle and sharpen the edge, and the sword is complete and ready to use. A skilled bladesmith can produce beautiful and well balanced swords by this method. At the same time, simple, brutal, effective swords can be produced in a matter of hours with appropriate tools.
Notably, stock removal can be used for any kind of blade one wishes to make, within reason. This includes longswords, knives, daggers, axes, spears, pole arm blades, arrow heads, javelin heads, and eating or working knives. It is open to debate whether a blade made by stock removal can match the properties of a forged blade, but for day to day military or defense use a stock removal blade is a perfectly good alternative to a forged blade.
So, there is your entirely too long, probably unwanted explanation of stock removal.
In the wasteland there is an abundance of steel to be had. Also there are widely available small, portable power sources. Small Energy Cells and micro-fusion cells are not rare. Moreover, if those are not available then more mundane technologies like solar, nuclear, steam, or coal power are available. Any of these technologies could be used to power a complete machine shop. Moreover, with plenty of pre-war tech and gear to scavenge you wouldn't even have to fabricate things from scratch!
