If the blades are ground one at a time, then backlapped, then they are being relief ground. :
: There is a grinder company based in England selling the No relief grind thing. I am not impressed with a mower that is totally dull and pulling at the grass in one week's time needing to go back to be reground at a shop. I can see a mower needing a backlap in 2 weeks and a full regrind in a year. The shops that spin grind only sell a lot of replacement McLane and Tru-Cut reels. Those jobs are not cheap either. Think around $500-600. A mower that is backlapped and not spin ground excessively can be on its original reel for a long time. Spin grind only and the reel lasts 2 years if you are lucky.
