Toro Edgemax bedknives is fine product . I would recommend them to courses with smooth fairways that seldom topdress . For the period that we had them for I was very surprised on how well they kept an edge . They say they keep an edge 3 times as long and I believe they will in ideal conditions . As far as grinding them I personally didn't think it took that much more time and used the factory stone on our foley grinder . There are better stones out there if your in a reel hurry to get the grind back .
There are guys on the tech sites that have over 800 hrs. and counting on their bedknifes . If I had different conditions I would gladly go back to them .
