Too smooth cork handles

[keithdog]

I have a 7 foot medium heavy casting rod with a straight cork handle. Over the years, this cork handle has worn itself smooth to where it is harder to hold a good strong grip. It's too slippery in the hand. I was wondering if anyone has any tips on what to do about this situation. I was thinking about maybe wrapping the cork handle with a grip tape such as that used on baseball bats. I'm not sure though how that type of tape would work with cork. I also was worried that it would get too sticky on warm sunny days. Or if maybe there is another way to improve the handles texture to improve the grip.
