Grind your teeth for no-stress flush cuts

While remodeling my front porch, I needed to flush-trim about 150 dowel plugs in screw holes without marring the surrounding surface. Using my bench grinder, I ground the back of my oscillating multi-tool's offset blade to remove any set in the saw teeth. I flush- trimmed all of the plugs quickly without damaging the boards.
