I have very similar experience as yours. There are indeed a lot of things I like about Sani-Tuff. It is heavy and dense, but not excess. The surface can be renewed by sanding it. It stays very flat. Absolutely no maintenance (no oiling or beeswax needed)…etc. However, all of my knives seem to dull much faster on my Sani-Tuff than any of my wood cutting board. The knives usually cut in a little more in the Sani-Tuff board and have that “sticky” feeling.
