Re: teak and holy sole
There used to be a product called 'Ultimate Sole'. It was a varnish with a wonderful gloss but didn't get slippery when wet. We've got it on our sole, and I liked the finish enough to use it on our table. When you wipe it with a damp cloth you can feel the 'grip'.
Unfortunately the company stopped producing it- but one might find some old stock somewhere... It does what you're looking for.
