I've been meaning to get my Victorinox chef knife sharpened for some time and I stumbled across Wisconsin Cutlery searching for professional sharpeners. I'm so glad I did because I end up signing up for their knife cutting class! It's a two hour for class for $30 and you'll get 10% off the entire store after the class. Aside from educating you on cutting techniques, you learn how to properly sharpen and care for your knives. Michelle (owner) is incredibly helpful and she knows her shit. I definitely want to come back and invest in one of the nicer Japanese knives.
