You can do this with adamantine already.
While you can make metal clothing from adamantine, it wears down at the same rate as all other clothing, and is thus a terrible use of strands. I avoided using the word until now to prevent HFS spoilers.
The maximum defense for an adventure mode dwarf would involve clothing of adamantine, topped with leather, the adamantine chain, then adamantine plate. Then all 15 possible cloaks in adamantine. Crazy but true trivia.
But what I'm suggesting is a modification of the existing metal cloth clothing.
I'll list them again more clearly.
1. Metal cloth clothing to be more durable.
2. Metal cloth clothing not being able to be ripped by wrestling sparring or combat.
3a. Durability number implemented into the raws for all base materials.
3b. Masterwork or Artifact items gaining a bonus to this number.
If number three is used it would be checked before something is damaged. Chunks and fish could have a very low number causing them to spoil quickly. Dragon hide a higher number causing it to spoil slower as raw hide waiting to be tanned. Low quality animals with bad suitability get low numbers here. The plan to make obsidian weapons break gives this a reason to exist, and expanding it to all objects as a raw entry makes it a fast way to be changed if wanted.
There's a throw away comment at the end about artifacts for l/r positions be in matching sets, but that's as trivial to me as it was tacked onto the end, like this.
