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?

Maybe to keep it sharp. Once it's dull you'd spend hours with that
thing. Just get yourself a bench grinder or a friend with a bench
grinder. 3/4hp or more works just great. Count the strokes you grind on
1 end then flip it and do the same number on the other end. I grind the
lower, outer, cutting edges on both ends first and then the inside,
upper mulching edges second. It doesn't have to be pretty and it doesn't
need to be knife sharp. Balance it on a nail or you can buy a balancer
for about $10.
