Having swords & other tools become dull, needing sharpening. Its wear bar lowers overtime with use, eventually using more stamina/doing less damage. You would need a grindstone not for flour, but for tools. Using these to sharpen your tool back to its top wear brings them back to normal function or even a faster function? Maybe require a nugget or so to sharpen it along with the grindstone. Rare chances for the quality to rise or drop by .1-.2 when sharpening? Sharpening would give blacksmiths more to do, like after a small to large battle, swords & other things would need working on again. Okay idea or too larpy?

I'm not saying tools/weapons would be destroyed at wear 0, just need materials to be patched up. So in the end you don't lose your q120 b12. But after killing stuff with it, would need maintenance.
