The Happiness of Scissors
4 Tips to choose a good pair of scissors
Scissors are an essential tool for every family, and good household scissors can bring us a lot of conveniences. Let us share with you some tips on how to choose a good pair of scissors.
1. Craftsmanship
The quality of scissors depends to a large extent on whether the workmanship is fine.
Observation of workmanship:
Firstly, check whether the inner edge line (there is a white light on the inside of the knife-edge, which is the contact track line between the two blades of the scissors) is even and smooth. If possible, open the scissors, and then close them gently to feel whether the cutting edge is smooth;
Secondly, check the smoothness of the guide rail. Now, most scissors guide rails are "U" shaped. Japanese scissors tend to be "V" shaped, but the ends of scissors must be smooth;
Thirdly, the handle of the scissors must be ergonomically designed, it is comfortable when using the scissors, the fingers are comfortable in the ring, the edge of the ring is smooth and round, the end of the hand is firm, and the tip of the knife is tight when closed.
2. Stainless Steel Material
The most important condition for a good cutting knife is of course better steel, such as food-grade steel plate 420J. Now high-end scissors also use 440C steel, with a hardness of 58 to 60. This steel already represents the best steel. Some Germany and Japan have 314 steel.
Some gloss of scissors is polished, but no matter how polished it is, the color of the light emitted by different materials of the steel itself cannot be changed, it is just a little brighter. Some scissor's steel is matte.
3. Fit for the test
Because everyone's fingers are different in shape and thickness, the same pair of scissors will feel slightly different for each person. But you must pay attention when trying the feel is that it must be opened and closed gently because the speed is too fast and it will cause empty scissors.
4. Sharpness test
Here are two simple methods: one is to take a single layer of facial tissue, wet it with water, and cut a slit with scissors. If the slit is smooth, it means sharp.
The other is to take a piece of thin cotton thread (The cotton thread on the towel is also fine), use the tip of the scissors to cut it. If it can be cut, it means the tip is sharp.
In order to cut two or more layers of fabrics accurately, special scissors should be selected. The most commonly used length is 24-28cm, that is, scissors marked with 10#, 11#, and 12#.
The key to distinguishing the quality of scissors is to focus on the cutting edge of the cloth.
First, check whether the two blades are sharp, the upper blade is in a straight state, the lower blade is slightly curved, and the heads of the two blades should be flush.
Secondly, check whether the two scissors are of the same width and thickness, and then the handle of the knife feels good in your hand, and it does not grind your hands or feel awkward.
The above conditions are ideal for scissors.
In addition, small scissors, also known as yarn scissors, are also necessary. They are mainly used for cutting thread or thread ends when hand sewing or sewing small parts. It is necessary to choose small scissors with a matched blade bite and good elasticity.
