I work at a baseball camp serving food out of a steam table. Sometimes when food runs out I need to cut up vegetables. one day my boss caught me cutting a cucumber and she stopped me and told me I need to be seventeen to use a knife in the kitchen. I'm fifteen and turn sixteen in two days. I was wondering if when I turn 16, can I use a knife legally? Any help will be appreciated, and if you have a "yes" answer please show proof that I can show my boss. THANKS
