As we say in the south, that stuff is "slicker than two eels copulating in a barrel of snot".
Seriously, I made some knives up with corian handles just to see how they would work out. Nope, no good. First, you can really damage the handle if you buff even a tiny bit too agressively. The buffer will definately eat corian up. Second, it is way way too slick for a working knife. Blood acts like KY jelly on the handle. Seriously!
I can get an unlimited supply from the local cabinet shop, but it only goes on knives I know will only sit in a case and be stared at.
My 2 cents.
