I did have a Triton ( basically cheaper Tortec copy ) for a while, and it did a nice job. It was very slow though. Good for sharpening, but I needed to use a sererate grinding wheel to re-cut the bevels, or fix a damaged edge.
The Sorby machine does generate some heat. Not as much as a regular stone grinder, but enough to have to pay attention to what you're doing, and keep a pot of water at hand. It has a range of belts from 60-3000 grit which work really fast. Also a small polishing mop, which is great for regular stropping as I work.
I use the Tormek T5 and 2 different diamond ‘stones’ with various jigs. I get great results but the very hard chisels take forever if they get chipped especially the 2” + sizes. Plane blades tend to see less damage and they only get sharpened on the dmt diamond plates. Your little machine looks neat, does it generate any heat in the blade?
