What verb akin to "refine" more clearly describes improving a skill that somebody is already good at?

What other verbs can be used to say "refine analytical skills"? I found "polished" and "sharpen," but I am interested in something better if there are any. The verb shouldn't indicate weak skills, but good ones that can be better. Any suggestions?

Thank you!


Solution 1:

Hone is a good verb for this

Refine or perfect (something) over a period of time

"she has taken numerous workshops to hone her skills over the years"
