Sharpens (5)

Ross

I believe the answer is:

hones

'sharpens' is the definition.
(honing is a kind of sharpening)

This is all the clue.

(Other definitions for hones that I've seen before include "Sharpens on strap, say razor" , "Sharpens as on whetstone" , "gets sharp" , "Perfects, sharpens" , "Sharpens, like knife on stone" .)

I've seen this clue in the Universal, the LA Times, the USA Today, The Wall Street Journal, The New York Times and the King Feature Syndicate.
