    I know alot of you swear by blade grinders to sharpen your blades. Could you give me a model of the grinders you use. Also what diameter wheel and the grit and where you buy them at. I assume you use a stone wheel of some kind but grinders come in many sizes and wheel diameters and grits. You input will be appreciated.

    Get the biggest 4.5" or 5" dewalt grinder you can buy. Not the ones you can buy at home depot or lowes. Places on line like toolup.com (dewalt's site has a bunch of where to buy links) I also am a welder. I know how fast you can burn up a cheap grinder. Also get a ton of flap disks. They work much better than hard disks when it comes to grinding blades. I have a blade grinder, but still use an angle grinder for wavy mulch blades.

    Used hand grinder and blade grinder both so I can speak from experience.
    Get the Blade grinder that uses the 8 or 10 inch wheel. RBG is what we use but there are others. Didn't like the Neary at all!!

    For shrapening blades, i just use a 4.5" Black and Decker angle grinder and a flap style disc. I paid $35 for the grinder(probably more now) and I get discs for $3 a peice, they last a long time.

    I use a thing called a Handi Disc.
    It's a bit more of an art than a science to sharpening with one of these as you need to keep it at a constant angle and move it across the blade.
    It's getting the job done until I can afford a real grinder.
    On the good side, it doesn't seem to heat the blade up.
    I might try one of those flap wheels

    Today I was sharpening my blades and realized it takes me much longer to do it with this abrasive disc than it would with a real blade sharpener.


    As soon as I can spare the money, I'm getting a real sharpener. :cool:

    My opinion the 80 grit flap disc is the only way to go. I've tried every way imaginable to sharpen my blades. The hand grinder, in the right hands, gives a faster and cleaner edge. It does take practice to become proficient but it's well worth it once you get it mastered. You can buy the disc for <$2 when you purchase them in bulk. I replace the disc after 10-15 blades.
