Unsure if I this is the right channel for tag suggestions themselves, but I am requesting the tag either singular or plural, chipped_scales, to be added.
I think that a chipped scale is distinct enough to be a separate tag, it should not implicate injury or scar, but can be accompanied by either.

You can make new tags on your own. This is TWYS and not extraneous, so go for it.

Though you may want to note that chipped_* gets aliased to notched_* and there exists broken scale (weighing scale) which may or may not come into conflict
