I have Yard Keeper, actually 2 and ordered 2 of the 311's. Can't wait to get them. I see in the description that they are going to be SR101. My Yard Keepers are SR77. After lots (I mean lots)of reading, I'm guessing that SR101 was chosen due to edge holding over the "pound-a-bility" of the SR77 as serious pounding would not really be an issue for a 3 1/2" blade. Would that be a fair guess?
Thanks,
Tom
