I have been looking at these sharpeners based on the Edgepro and trying to decide if they are worth a try for the little money they want. By the way, the self righteous indignation I hear about these machines makes me chuckle. Edgepro's patents ran out a long time ago. So there is nothing illegal or unethical about buying these. I work in research and have many patents. That is the nature and purpose of patents, to protect the inventor for 17 years, and to teach the invention to advance the technology.
It is kind of like if you had invented the light bulb, had 17 years of charging a high price and enjoyed huge profits, and then being outraged once the patents ran out when someone sells them for the actual price of manufacture plus a small profit.
If you watch Edgepros videos about these sharpeners, they never say they are illegal, they say theirs is better for some rather trivial improvements they made, for ten times the cost.
