New 21" Blade Edge Finish

[ILENGINE]

Darryl, in theory the blunt edge is best according to the manufacturer, but in reality when they are resharpened you will get one edge somewhat blunted, but the either end will be razor sharp because you had to take more off that end to balance the blade.

No doubt that a sharp edge will chip, roll and dull pretty quickly but I mow professionally and any uncut piece of grass drives me nuts, so to me the sharper the better. They hold up pretty well and stay sharp on my nice lawns that are cut at 4 inches. It's the crappy, poor soil lawns with bare and thin areas that I cut shorter (crappy lawns look really crappy cut tall) where they dull quickly. It's the grit that gets you...
