很多美工刀为了方便折断，都会在折线工艺上做处理，但是这些处理对于惯用左手的人来说可能会比较危险，使用时应多加小心。不要认为美工刀脆弱，如果使用不正确的话，美工刀造成的伤口同样可以致命，所以，使用过程中，务必要小心（ 因为做工处理的缘故，美工刀造成的伤口不容易止血 )，小伤口可用绷带解决，但是一旦过大过长或者伤及主要血管( 如手臂上的动脉 )，会造成大出血，血液像喷泉一样喷出，如不及时包扎，可能会因为失血过多而引起休克，甚至死亡。

The utility knife is also commonly known as a knife or a wallpaper knife. It is a kind of knife used for art and handicrafts. It is mainly used to cut things with soft texture. It is mostly composed of a plastic handle and a blade. It is a pull-out structure. There are also a few metal shanks, the blades are mostly slanted, and the smear can be broken with the scribe line, and a new blade appears, which is convenient to use. The utility knife is available in a variety of sizes.
When the utility knife is used normally, only the tip portion is usually used. Cutting, carving, and punching are the main functions. Because the blade is very brittle, it can’t extend too long when used. The hardness and durability of the blade (the two concepts in the utility knife) are also different because of the different texture of the blade. The choice of the handle should also be selected according to the hand shape, and the grip gesture is usually described behind the package.
Many utility knives handle the folding process in order to facilitate breakage, but these treatments may be dangerous for left-handed people and should be used with care. Don’t think that the utility knife is fragile. If it is used incorrectly, the wound caused by the utility knife can also be fatal. Therefore, be careful during use (because of the processing, the wound caused by the utility knife is not easy to stop bleeding), small wounds are available. The bandage is solved, but once it is too long or too long, or the main blood vessels (such as the arteries on the arm), it will cause massive bleeding, and the blood will spurt out like a fountain. If it is not wrapped in time, it may cause shock or even death due to excessive blood loss. .
The difference between the utility knife and the knives is that the knives are short, the knives are thick, and the sturdy and sturdy are particularly suitable for engraving all kinds of hard materials such as wood, stone and even metal materials; the knife blade is long, the tip is oblique, and the blade is thin. It can be used for engraving and cutting relatively soft and thin materials such as paper, soft wood and so on.
