Hey Wes, Sorry I didn't see the knuckle deep part. Guess I need bifocals now. Anyway, I think the teak oil would be the fastest way to deal with it. However I once, and only once bridged a hollow by cutting the upper leading edge of the callous every year for several years. Now, I grant you it was only about an inch but it did work. Took some time though. I think now that I been prattling on, is work with what you got. That didn't help much did it.
