Not as well made as Bearcreek's
but it works for me. It is a float with a notch that I purchased at the masonry section of HD. With a wide board I use it flat with the attached cleat and it holds the board tight against the fence. With a narrow board I hold it on edge and my hand is to the right of the blade, not over it and the handle rides nicely along the fence and I have the comfort of a piece of wood between the blade and my hand. Yes, I use the guard almost always. I am a belt and suspenders man when it comes to safety.
