    I recently purchased your AV-54 automatic knife grinder to sharpen my personal planer knives. Our old grinder broke down and I was looking at your machine and other machines that would have costed me a lot more money as well. After a couple phone calls with Thorvie, I had the confidence that this grinder would fit my needs well. It was very easy to set this machine up and learn how to use it. After I sharpened my first 5 set of knives and tested them, I could not believe how sharp my knives were. My old grinder would sharpen a dip in the center of the knives and when you put the cutting edge of the knife on a work bench, you could see daylight in the center of the knife. This grinder sharpened the knives perfectly straight. I never understood how a hollow ground knife made that much difference from a straight ground knife until I have tested it for myself. Thank you for saving me a lot of money and making a product that will fit my need for many years to come.

    I own a Powermatic model 225 24” planer. I bought this system for my own use, not to start a business. I knew nothing about sharpening, although with a little help from Rick at Thorvie I was soon up and sharpening my own blades. I buy my blades from Terminus and after one re-sharpening by Terminus the knives are no longer any good. With my AV-54 I can now get 3-4 sharpenings out of those same Terminus blades. At $250 for a new set of knives and $176 for Terminus to sharpen them, the AV-54 is saving me well over a thousand dollars, if not more, a year. I mention this because most people that buy this equipment are starting a business, I am at the other end, the end user and I can tell you the equipment does a wonderful job. I am very satisfied with my AV-54. IT PUTS A BETTER, LONGER LASTING EDGE ON THE KNIVES THAN TERMINUS DOES. Thank you for a well made product that is made in America.
