Hello Tekebo, I always show up to the race late, maybe because I like to give others a head start. Here though I'm inclined to think there probably right, all cutting boards were not created equally, that's evident of the condition of your knife after some use on various boards. Personally I like an end grain board because they wear slowly, they are durable, they have enhanced knife preservation, self healing properties and lastly...they are as handsome as hell. You know I use to make cutting boards, gave em out for Xmas and gifts although they weren't end grain....preparation in sanding was an issue while exposed long grain was easier to fashion. Never did think much on damage to my knives, every few months I'd just sharpen the lot. I would still have to say though, I prefer a board that turns heads just like a pretty girl. A wooden board will always have my heart and be on my table, it's naturally attractive.
