Oh it's okay, I'm not sure Adam's little hatchback would make it down here anyway. Meh, still better than my Civic I suppose....
(pray for me)
and about the poly boards:
Polyurethane cutting boards, aka, the big ugly plastic things you use all the time in kitchens from here to Tim-buck-two.
Color coded usually, and slightly textured, although there are some smooth ones (which I recon would be better on edges a little bit). The toughness of the plastic tends to kill refined edges rather fast. A 2k edge on VG-10 will last you all shift on poly, whereas an 8k edge will die rather fast. It just makes the steel roll over like crazy. I guess this is why some people prefer to use a softer steel and beat the daylights out of it with a steel, to "tooth" that edge up. (and destroy the knife in the process)
Sidenote: Just because 2k outlasts 8k on poly, that doesn't mean going coarser than 2k will give you more edge life. I actually find that a 500 grit edge doesn't last as long on a rough board because you then start to suffer from a type of carbide fallout. The steel simply can't support the big nasty teeth, and they all rip out. 1k to 2k just seems to be that sweet spot for poly, and you can sometimes get away with 4k. I'm talking, these edges last with no stropping during the shift, that's what I mean by edge life.... no steeling, no nothing, just straight edge life from stone.
End Grain cutting boards are the most desirable. There is 'side grain' and 'end grain' when it comes to wood. They look like what they sound like: The side grain has a long grain pattern that extends across the entire cutting board. End grain is usually a collection of little blocks, as you are cutting cross-sections, and then placing them back together. There is a big difference in edge life when it comes to side grain versus end grain. End grain is much softer on the edge, and if you've never used one you'll love how long your blade stays sharp on one. Even refined edges last on end grain maple boards.
Now side grain: Mostly going to be a bamboo board (already hard stuff) and side grain makes it even tougher. Side grain bamboo sucks, I'll say it like it is. End Grain bamboo is pretty good stuff though. Not as good as maple, but still better than poly. I'm not sure if side grain is worse than poly though.. that's a tossup.
