I hate to admit this but my knife skills suck! I was happily ignorant of the fact, chopping away quickly and neatly, at various jobs, until I began school. My little 3-D model sits there and mocks me. I can NEVER seem to get a julienne just right. Obviously, I won't have time to measure each and every batonet or matchstick. My tournes are more likely to have six sides than seven. I only have time for an hour of practice a day, with work and classes and studying. How long does it take to become proficient?
