Low-Tech circular saw blade sharpening jig!

Plans at https://www.stevemaskery.com/jig-plan... This circular saw blade sharpening jig handles all sizes of blades in my workshop, from my little biscuit jointer blade (100mm) up to my SCMS blade (12"). It also handles all the various rake angles, too. And the best bit, it is quiet, gentle, and doesn't fill the air with tungsten carbide dust. What's not to like?
