If you’ve ever bought a ceramic knife, it probably came with instructions, in the package, to return it to the manufacturer for resharpening instead of trying to do it yourself. This video is kind of a giant Kyocera commercial, but it does include some cool footage of what this process actually looks like, in case you’ve ever wondered. Turns out it looks somewhat like regular knife sharpening, though I imagine the specific abrasive media in use are different. The good stuff starts around 0:44. And yes, for the safety conscious: as a general rule, in any operation involving a sharp edge, you should probably put it down before adjusting your facemask.
