I’ve seen the worksharp. I have something similar that was built in the 60’s. It’s awful, but that’s mostly because it doesn’t have a very good tool rest and relies on operator skill (which I totally lack) to keep the blade square on the disk. I’ve also got a reasonably decent set of waterstones, and several granite surface plates I can put sandpaper on. The honing guide I have is a clamp type, so it won’t accept certain of my blades, and for the ones that will fit, it also relies on operator skill (which I totally lack) to set up to get the proper angle. I’ve been thinking about the Veritas MKII honing guide system. It looks like the setup jig on that one takes a lot of the guesswork out of it, and the deluxe set has the adapters for my unusual blades.
I’ve also been thinking about the smaller and less expensive Tormek machine. Still thinking on the subject.
