Hi all,
I generally find if the blades are not too bad you can just simply take the bur off the backside of then with a hand grinder and that is sufficient. Generally you can get a satisfactory cut with dull edged blades as long as they are not burred over as the burrs rip rather than cut. If the blades are a little worse or you are cutting them doun to fit a different mower (defiantly not recommended to anyone) I find taking them off and sitting then together, then cutting or grinding a clean edge on them is the best way to go to keep them balanced. You can then sharpen then put the cutting edge on them separately and weigh them if you like. But after this type of operation you may as well have spent the $4.99 at the mower shop and got new blades and bolts.
