First what i like to do is pick a straight edge knife and sharpen the knife then rinse it and wipe it off to remove loose metal particles. I set the knife on the counter next to the sink and grab my favorite bamboo cutting board and set that on the counter next to the knife. I walk over to the fridge and open the crisper drawer and pull out whatever vegetable I feel like eating; usually a carrot, cucumber or tomato. I rinse the produce off and set it on my bamboo cutting board. I pick up the knife (preferably a santoku) and begin slicing by pushing down and forward and then pulling back while still pressing down. The knife should be held in somewhat of a fist without any fingers extended. I push each slice away from the main piece each time. Once I am down I pick up the cutting board and use the knife to slide the vegetable slices into a dish.

Who chopped the vegetables?
