The rim of the blade is wider than the disc of the blade. This is by design so that the blade cuts a slot that is wider than the disc, thus preventing the sides of the disc from coming into contact with the material being cut. If it were to come into contact, the blade would bind up, and both blade and rock would heat up. When the rim gets worn down and is no longer wider than the disc, it can be restored by lightly tapping all around the rim of the blade with a ball peen hammer to flare the rim out again. Care should be taken to strike the edges straight on so that the rim remains perpendicular to the plane of the disc.
