Mod request: Sharpening weapons, a temporary improvement in armor

[Bumbum]

Sharpening does not go away with time, but disappears from the amount of damage caused by weapon strikes. For example 100 beats fully spent sharpening weapons. If the weapon is replaced, it also ends.
Similarly with armor. Their improvement should be spent from-for hits on them, and not over time.
If someone can do it, I would be happy.
