I have an arsenal of power tools, but when I need to make a few cuts, this does the trick. I have another Japanese saw with a support rib at the top, but the rib prevents using it in a miter box. That is where the 10-2440 shines. If you use it to cut miters, I recommend clamping your workpiece, or putting adhesive-backed sandpaper on the miter box fence, because pulling on the saw can make the workpiece creep.
