I really liked this project. I do woodcarving and my knives are nearly flat with the exception of a couple of brands. I am going to think about modifying this for my needs. Might include some magnets to hold the blades close to the guide but - need to figure out how to adapt this to my VS (now that I converted to a treadmill motor) HF 1" x 30" sander. Thanks for an interesting Winter project.
