    First time posting here, very nice site!

    Who can tell me what angle to sharpen a Ninja Blade? I sharpened mine today and I could have sworn I followed the previous angle but, it seems it is leaving some grass down the middle that isn't being cut quite as well as the rest.

    The only thing I can think of is that I got the angle wrong?

    check out the other active thread on blade sharpening going on right now. I doubt angle is the problem unless it is WAY WAY off. and you should see that. Here is a big problem that unfortunatly I have had myself. The very tips and ends of the blade where the sharp edge starts are crucial. if you sharpen and nick a tip BINGO instant possible missed strips. Other questions to ponder....... What type mower is it on. Is the deck free of grass buildup? If it is more than 1 blade turn them around and see if the tips of the blades are level with each other. also bad deck bearing or bent spindle can cause this. Hopefully it is just something minor. Good luck.
    P.S. I have a ninja blade on my Snapper push mower at home. I have found that an angle grinder is about the only way to sharpen the whole blade due to its design. A regular bench grinder just wont do it.
