I've tried 4 types of plastic. This is now the one I use. Or at least the material. It allows some
penetration by the knife the way wood does. The hard acrylic ones are death to knives. And I find these kinder than the flexible type, maybe not what Heather is indicating but the flexible ones that I've tried.
But the Epicurean one that you mentioned looks even better.
I like to be able to put these things into the dishwasher.
