Shaperblade do they really self-sharpen?

    I was looking at shaperBlades in turf magazine. "The mulching lawn mower blade has a cutting width of 17 to 22 inches and is self-sharpening, nonsparking and made of polymer." That is what the description says. Just wondering if they really are self-sharpening, how much and are they worth it?:usflag:

    Thanks in advance for any info.

    How would it sharpen itself? Does it have a file that goes to work when you stop mowing? ;)

    no such thing as self sharpening!

    self sharpening is easy.

    all they have to do is laminate constuct the blade and as the edge wears down the sides fall off exposing an new sharp edge.
    The problem isn't with self sharpening, the problem is with durability. Hit a rock, hit a big twig and you grenade a blade. Then the fact that it "sharpens" at a preset rate may dramatically decrease the life of your blade.

    I was going to ask about these blades, guess I dont need to now. I prefer my steel blades that will be repairable if they hit something.

    That we have, they're called robomowers. You have to set up an invisible fence for them (like with flags) and 'train' it the first time around and oh by the way, I wouldn't leave the dog outside and make sure your yard has a VERY solid fence all around lol

    why even bother fixing a $10 blade?
