selection and maintenance of knives

I. knives for kitchen workers and home kitchens are tools for food cooking operations. Knives can be selected according to their purpose, and are generally used for segmentation, shredding, slicing, cutting pieces, bone cutting and other functions. Thin knife should be selected for cutting and batching; Cutting and cutting cooked food is better with a stainless steel driver's knife; Those who need to cut bones should choose a bone cutting knife. It is reasonable to use a slice knife and a chopper in the family kitchen. The manufacturing raw materials and production and processing technology of the knives are divided into:

1. Pure steel knives: stainless steel, slaughtering knives, etc. the production technology is stamping molding, which should be cut rather than cut

2. Steel embedded cutting tools: such as traditional carbon steel and composite steel cutting tools, the production process is forging forming, which is suitable for cutting, cutting and easy to rust

selection method:

1. Select the two sides of the tool: flat and smooth, without forging dents

2. The thickness of the selected blade is: the steel exposure is moderate, the blade edge is straight without distortion, and the blade is in a black straight line when looking directly at it, without "white blade"

3. The back, head and heel of the knife are ground smoothly, "no black exposure", no burr and no handle

4. The knife handle is installed straightly and firmly, and the knife hoop is not loose

use and maintenance:

1. Please use the bone cutting and meat cutting separately according to different purposes. The knife should not cut or cut metal, wood and other hard objects

2. When cutting bone, the heel of the blade should be used to contact the bone. At the same time, the blade edge should be selected as an obtuse angle. It is suitable to cut bone and drop the knife vertically. If the bone bites the blade, do not shake it left and right, and try to pull out the blade. The correct method is to lift the bone together with the knife and then cut it until the bone breaks. Otherwise, the cutting edge will break steel and form an arc-shaped gap, which is improper use and is not within the scope of warranty

3. After each use, the knife should be cleaned, wiped dry and smeared with cooked edible oil. It should be placed in a ventilated and dry place away from water and gas stoves to prevent rust. (when stainless steel knives are exposed to carbon monoxide gas, they will produce yellow spots, which should be prevented)

4. The traditional household rust prevention method is to soak the carbon steel knives in rice swill frequently to prevent rust

II. Scissors household scissors can also be purchased in different models and specifications according to their use needs. Generally, No. 1 and No. 2 civil scissors are suitable for families to make clothes; 3 #, 4 #, 5 # civil scissors are suitable for clothes machine lock button opening, and steel nail scissors are suitable for cutting fingernails and toenails; Long head scissors, elbow scissors, etc., 7 # and 8 # small scissors are suitable for family embroidery and thread picking. Suit shears 1 # and 2 # are for professional sewing workers to cut materials, generally men's 1 # and women's 2 #; 3 and 4 are for family cutting clothes

purchase method:

1. Check whether the two foot rings are flat and the arc is symmetrical

2. Check whether the cutting edge of the scissors is straight and without notch

3. Check whether the tips of the two scissors heads are neat, close together and not misaligned (commonly known as "over head")

4. Check whether the steel on the blade is evenly paved, and the steel on the outer edge is clear, without ash, broken steel and soft edge. In the trial, the opening and closing of the blade are very smooth, without knots, so as to achieve the environmental feeling of "moistening things silently"

use and maintenance: when using scissors, pay attention to the consistency between the objects cut and the bearing function of scissors, that is, scissors of a slightly larger size should be used to cut thick layers of cloth; Use sharp scissors to cut thin layers of soft and slippery objects, otherwise it is easy to be damaged. Pay attention not to pry hard objects with the tip of the scissors. Generally, civil scissors are not suitable for cutting metal hard objects. When using the scissors, if the opening and closing feel too tight, there is a simple way, that is, hold the scissors in your hand, aim at the nail and knock it on the hammer, and the more you knock it, the looser it becomes, until it is suitable. On the contrary, if the cutting edge of the scissors is too loose when using, place the scissors nail on the iron pier, and tap the scissors nail gently with a hammer with the other hand. The force should be moderate when tapping, not too heavy. Rotate on both sides, and try while tapping until it is smooth
