    I bought an angle grinder from Lowes for $29 yesterday. I got tired of paying $4-6 each for blade sharpening. I always buy name brand stuff like DeWalt etc... but, this thing looks good and has a 2 year warranty. They must be serious about it because there's a receipt holder in the box, just take it back to Lowes for replacement. I solved my no-vise problem with my trailer rail and some vice grips. Oh yeah, it's also a variable speed unit.

    Add a 36 grit flap disc to that grinder and you've got one mean blade machine. That price sounds great!

    Yeah I've used the trailer rail before but the vise eventually scrapes the paint to the bare metal, then it rusts.
    Nowadays, I usually hold the blade with one hand while I grind with the other.
    What this does:
    - Makes me pay CLOSE attention.
    - Only allows light pressure from the grinder, less burn spots.
    - Does a finer job.

    I bought a DeWalt disc, a couple of bucks.

    I must have missed something when I have read other posts concerning using angle grinder to sharpen blades, presently I am using a angle grinder with metal disc, in this post mention was made of using 36 grit paper disc, please tell me why 36 grit paper disc is better. Thanks

    That is a good guestion I use 50 grit put ontop of a metal cut off wheel. I don't take off much material when I sharpen. I am guessing that if you really want to grind the material away to take out big pits you would use the metal grinding wheel?

    buy a blade grinder and you'll be glad you did. You guys are sharping blades on mowers ranging in price from $2000 to $10000 with a $30 grinder? A blade grinder can be had for $400 and I have never had to replace the ruby wheel on my blade grinder (6 years old). With a blade grinder you always get a perfect bevel time after time.

    I haven't found any bench grinder that I thought could do mulch blades, does yours do those?

    Depends on the type of the mulch blade. It will do certain types. However, I don't mulch.
