1 Maintain, handle and clean knives Unit 102 (1GEN7)Maintain, handle and clean knives
2 Parts of the KnifeThe parts of a knife are pretty much the same for all knives.
3 Parts of the KnifeThe point is where the spine and the cutting edge come together. It is used for delicate work and to pierce foods.
4 Parts of the KnifeThe tip is the first third of the blade. Because most blades taper in thickness from heel to point, the tip is the thinnest, lightest part of a knife, and is therefore well suited to delicate work such as chiffonading basil or cutting soft fruits and vegetables.
5 Parts of the KnifeThe spine is the top of the blade. On forged knives, it is usually thicker than the rest of the blade, and can be squared or rounded. In the basic grip, the thumb and index finger pinch the blade below the spine.
6 Parts of the KnifeForged knives have a bolster, located where the blade and the handle meet. The bolster protects fingers from the edge while lending weight and balance to the knife.
7 Parts of the KnifeThe handle is what you hold the knife by. Handles come in many shapes, sizes and materials, and can be solid or hollow. Common materials for handles are wood, plastic and composite resin.
8 Parts of the KnifeThe tang is the steel that extends from the blade or the bolster into the handle. The tang gives a knife strength, durability, balance and weight. Knives with full tangs are considered stronger and more reliable for heavy work.
9 Parts of the KnifeThe scales are pieces of wood, plastic or composite resin that enclose the tang to form the handle on a riveted knife. There is one on each side of the tang, and they are held together by metal pins called rivets.
10 Parts of the KnifeThe heel of the knife is the back third of the cutting edge, up to the bolster. It is thicker and heavier at the spine than the rest of the blade and is therefore well suited to heavier work, such as cutting through thick skin and chicken bones.
11 Parts of the KnifeThe cutting edge is the part of the knife that does the work. There are many different types of cutting edges, each suited to specific tasks
12 CARE AND SAFETY OF A KNIFE Sharpening a knife – The correct method of sharpening a knife on a steel will be demonstrated and taught in the kitchen. The basic rules are as follows:The steel should be held at an angle of 45° to the line of the shoulder, with the knife held almost perpendicularly, the hilt of the knife should be placed at the tip of the steel and the blade drawn downwards the whole length of the steel and the knife without under pressure, first on one side and then on the other, so that the point of the knife finishes at the hilt of the steel. The blade of the knife should be held the steel at an angle of 30°
13 KNIFE SAFETY RULESFollow the knife safety rules for the safety of others and yourself.It is the responsibility of all food handlers to act in a professional manner and to learn how to handle and maintain your knives.

15 KNIFE SAFETY RULESKeep knives clean for each separate task to prevent cross contamination.Knife handles should be kept clean and dry to prevent the knife from slipping.Clean a knife with the edge away from the fingers.Carry knives with the point held downwards and the sharp edge facing.
16 KNIFE SAFETY RULESAlways offer someone a knife by the handle, never by the blade.Place knives flat on a board or table.Do not allow knives to protrude over the edge of a board or table.Never place knives in a sink of water, drain water first before removing knives.
17 KNIFE SAFETY RULES Always use a chopping board to cut ALL food items. If possible use the correct colour coded boards.Do not cut directly on a table as this ruins the blade and marks the table.Ensure the cutting surface is secure by using slip mat, wet paper or a cloth.
