It's a logical word (and, as I recall, I eventually went with it) in the sense of someone or something that pares. https://www.thefreedictionary.com/parer But it's fair to say that it's not at all common in the US. Someone would normally say they were going to the manicurist or ask you to hand them the paring knife--though, at least in the latter case, they might intuit the meaning from context.
