I'd like to keep my mulching mower blade sharp over the mowing season,
though as I understand it, the extra ridges make it more difficult to
sharpen. (Last season I took one to a mower shop and it came back
duller than it went in.) Would one of those hand-held sharpeners like
the one pictured at the link below be effective on a mulching blade?http://tinyurl.com/aku75q

Don't know what your mower blades look like but my Lawnboy has a
regular blade plus other, shorter ones on top that keep the grass
blowing around when the exit chute is blocked so that the blade can
mulch. I just touch up the blade with my Dremel tool with a small
grinder on it.
