What a great sharpener. I never sharpened blades before. But I knew I needed to handle this myself instead of paying somone eles. WHat a breeze it is, after a few hrs of getting the hang of it and can sharpen, balance my blades in 5 mins. I even had the person doing my blades come take a look at it, and he was impressed. Worth the money ill be saving by doing my own maintance.
