Fine-tune, as skills (4)

Ross

I believe the answer is:

hone

'fine-tune as skills' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for hone that I've seen before include "Polish" , "Strop" , "Sharpen tool on stone" , "Smooth stone" , "Sharpen (a blade)" .)

I've seen this clue in the LA Times.
