nick, you're on crack. if you smear enough petroleum jelly on a blade, it won't matter what it's coated with, and it'll cut just fine. I'm just used my yard hook to cut some doughnuts in half so I could fill them with cheeze whiz, no problem.
Ok, I just came up with that off the top of my head-to get my point across. And who wants petroleum gelly on there food? Or Cheez Whiz in there doughnuts for that matter.
