Like, I'm guessing, a lot of folks on here, I've gone through a lot of different cutting boards and board materials. I've developed my own opinions on each material and its effect on blade edges, but I've never gathered anything beyond anecdotal evidence to actually answer the question of which materials are best on knife edges and how much difference exists between the different materials.
The main materials that Im thinking of are:
-end grain maple
-paper & resin (epicurian)
-hard white plastic (ploy)
I've read comments about "oh material X is horrible on edges! you should use Y instead." but I've never seen any quantitative data to back it up.
So, calling all board geeks: what do you know?
