Why didn't you simply lock the knife down stationary and use a guided system? Your setup will get a knife sharp but it'll not get one as sharp as how I just mentioned (please see Wicked Edge, KME or The cheap new sharpener out made by Work Sharp)
The main reasons are: - With those systems, the stones are not as wide as the knife. This creates several problems, the chief of them being that it can be very hard to keep the knife edge dead straight, which is important for evenness across the edge and scraping the reed evenly. - With these systems, the stones are proprietary. Most players already have stones that they like and and I wanted to give them the options of using those. This allows for a far wider variety of possibilities. - The clamping of the knife in each of these systems is not designed for double hollow ground knives. I used the Wicked Edge for years and it was one of the most frustrating aspects of the system, and one of the big reasons that I developed this one. Without perfectly replicable clamping that is quick/easy to use, the results will be inconsistent. Also, the clamping issue really limited the types of knives that could be used with those systems, well-designed as they are. - The clamping on these systems does not allow for sufficiently low angles. There are others, but these are the main ones.
If your wanting a knife sharpener that's easy to use and maybe easy to manufacture and get to market maybe get in touch with me I've got an idea I'll gladly GIVE YOU that most likely will do the trick
