The ghurkas sometimes make theyre khukuri knives from from leaf springs taken from the suspension of trucks:

Back in medieval times they had these broadsword type things, with only 1 sharp side, which were heavier and thicker than most swords, probably because of lower quality steel used in them and because of the extra weight would eliminate the need for special training with them.
You would just whack your enemy with it, just like you would while swinging a club/stick, only instead of blunt force trauma you would inflict a nasty cut on your target.

These were then issued to untrained troops, militias/peasent soldiers. I cant for the life of me remember what they were called, I thought "rapier", but that wasnt it. I think theyre actually called cleavers, but Im not sure. They look alot like long heavy machetes with a sharp point.
EDIT: Remebered what theyre called, apparently its Cutlass:

Best known as the sailor's weapon of choice, the naval side arm, likely because it was also robust enough to hack through heavy ropes, canvas, and wood. It was also short enough to use in relatively close quarters, such as during boarding actions, in the rigging, or below decks. Another advantage to the cutlass was its simplicity of use.
Now look up something on what was actually used in medieval times, and note that swords were *not* common at all.
Spears, axes, hammers, farming tools etc. were much more common because they had other uses and/or were a lot cheaper and easier to make, costing much less metal.
Hence that's what gets used most in a post-apocalyptic environment, not swords.
