Good tools make any job easier and being a chef is no exception. The exact equipment required will vary depending on the exact job you're doing (and may be provided by the college/establishment) but there are some basic tools every chef needs -- and every chef should be practiced and efficient with them. These are the most basic elements of your job.
• Full set of knives.
• Smock or apron.
• Hair net or hat.
• Pots and pans.
• Knife sharpener.
• Spot towels.
Don't forget to invest in a pair of sturdy but comfortable shoes; you'll be on your feet all day. A good selection of cookbooks (both old and new) is a great help too; not for stealing recipes (!) but for inspiration, to get a sense of the history of cooking and to keep up with new trends.
