Yes! Great!
Had to clean off a large supply of a white grease/gunk when I bought my large regular used.
In answer to your other question about lubing without dismantling, my answer would be Yes. Use TufGlide.
One thing, Jeff, since TufGlide is so thin, and much of it evaporates, you may well need more than one treatment of it to attain the desired results. The Sebenza is so smooth that isn't going to be as much of a problem as it has been with other knives for me. Frequently, I apply TufGlide for 4-5 consecutive days before I get the lubricity I want.
