The "attrishing" in your comment made me go looking, and Wiktionary [0] says the verb form "attrit(e)" exists and is likely a quite old backformation that has fallen out of common use.

I wouldn't quite say attrite has fallen out of common use, though it is by its nature rarely encountered. I certainly use it, and it's fairly common in certain fields (e.g. discussions of language attrition, ironically).
