1 Foods I Unit 5: Knives & Cutlery “One of the most important skills to master”

2 The History Behind the Cutting Tool Stone cutting tools are believed to be around 3 million years old. Before mining evolved knives were produced primarily from flint and obsidian. Flint, a stone particularly suited to take an edge, was created to take a thin cutting edge. Obsidian, a volcanic glass, took even better edge and was noted to be more durable. After mining evolved and pure metals were extracted miners learned to blend metals together and create new properties. Carbon steel was the first widely used metal for knives which made knives more durable and hard enough to take an edge.

3 The Parts of the Knife The knife is constructed from several parts, each of which plays a role in the utility, balance, and longevity of the whole. Knives should be selected for quality and comfort and feel balanced in the hand. 1. The Blade (Cutting Edge): 2 Types  FORGED: ADVANTAGES: DISADVANTAGE:  STAMPED: ADVANTAGES: DISADVANTAGE:

4 Blade Material MaterialProCon Soft metal and easy to sharpen Looses edge, discolor, and leave metallic taste Does not discolor or leave a metallic taste Harder to sharpen Easy to sharpen, does not discolor or leave a metallic taste -------------------- Sharper edge and does not leave a metallic taste Fragile and can chip or break when dropped on the floor

5 Blade Shapes *V-Shaped blade with a fine point *Good all-purpose knife *Blade with an extremely sharp edge *Carving and Slicing *Row of teeth *Slicing and Gripping *Series of small arcs *Slicing and Gripping *Blade with grinded ovals *Cutting moist foods (non-stick) *Edges are one sided *Japanese style knives

6 The Parts of the Knife 2. The Bolster (Collar or Shank):

7 The Parts of the Knife 3. The Rivets

8 The Parts of the Knife 4. The Tang: 3 Types of Tangs 1. ____________: runs the entire length of handle and more durable 2. ____________l: does NOT run the entire length of the handle and less durable. 3. ____________: Encased in the handle and less durable.

9 The Parts of the Knife 5. The Handle:

10 Types of Knives Multi-purpose knife and is the most versatile in the kitchen (8”-12”) chop, dice, slice, mince Multi-purpose knife that is a smaller version of the chef knife (6”-10”) clean, cut, carve Smaller cuts, garnishing, peeling (2”-4”) trim, peel, garnish Thin/ narrow blade for easier slicing (10”-14”) carve, slice

11 Knife Safety  NEVER catch a falling knife  NEVER leave a knife in the sink place on counter  ALWAYS wipe a knife’s blade facing outward  ALWAYS pass a knife by laying it down on a table or giving the person the handle first  ALWAYS walk with knife tip down by your side  ALWAYS dry a knife completely  ALWAYS use a cutting board  ALWAYS store knives in proper containers

12 Knife Skills & Techniques The Knife Grip… provides the best control, stability, safety, and accuracy. 1. Thumb rests on opposite side of knife 2. Index finger rests on the side of knife blade 3. Three finger grip on the knife handle Consistency is the KEY for successful knife skills!

13 Knife Skills & Techniques The Guiding Hand is responsible for guiding the item to be cut into the knife. 1. The guiding hand is placed next to the knife blade in the proper position with fingertips slightly tucked under. 2. The guiding hand should be near the back half of the blade (not the tip). 3. The side of the blade should rest against the knuckle of the middle finger on the guiding hand.

14 Knife Skills & Techniques The Cutting Movement where the knife blade is curved and allows the knife to have a smooth, rocking motion. 1. With the front third of the knife on the cutting board, being rocking the blade of the knife up and down along the curve of the blade. 2. While rocking the knife up and down allow the tip of the knife to slide forward a few inches o the downward motion and pull back on the upward motion.

15 Basic Knife Cuts Chop Mince Slice Rondelle (disk shaped) Diagonal (oval shaped) Oblique (rounded w/ 2 angled sides) Stick Cuts Julienne (1/8 “ x 1/8 “ and 2 inches long) Batonnet (1/4 “ x ¼ “ and 2 inches long) Chiffonade Dice Cuts Large Dice (3/4 “ x ¾ “) Medium Dice (1/2” X ½ “) Small Dice (1/4 “ x ¼ “) Brunoise (1/8 “ x 1/8 “)

16 Did YOU Know? A sharp knife is safer and performs much better than a dull knife. A dull knife requires more pressure or force to cut through food, making it more likely for the knife to slip, which could result in serious injury. A sharp knife requires less force and therefore allows the user to focus on technique and safety.
