The 10″ Micro Kerf Blade is a carbide-tipped, 40-tooth blade meant for both rips and crosscuts. Total Saw Solutions claims the saw kerf is half that of a standard thin-kerf blade, as thin as the width of a dime. This is one finely machined blade — the plate is precision ground and tensioned so that runout is less that 1/2 the thickness of a human hair.
One of the many advantages of the narrower kerf is that it produces less waste and sawdust while leaving a smooth finish. The blade also runs quieter and uses less energy. There are always downsides: you can’t make as deep of a cut as a regular 10″ blade because of the stiffening plate, the thinner blade is easier to bend, and even though it can be sharpened 10 to 15 times, it’s too fragile to take it to your local shop to be sharpened.
Not only does Total Saw Solutions manufacture this blade in the USA, all materials including the steel for the blade and the packaging are purchased in the USA. The Micro Kerf Blade doesn’t come cheap; it’ll run you $175 at Rockler. Having the blade resharpened and “hammered flat” costs $20.
