Abstract: Art knife is a very common cutting tool in life. It has a wide range of uses, and many families have art knives in their toolbox.

Second, the use skills of artistic knives.

1. On the blade of the art knife, we can see that there are many tiny twill lines on the blade. Why is there a piece on the blade? The art knife is easy to blunt when used for a long time, but it is not easy to use when used to cut things.

At this time, we can take off the back end of the handle. There is a plastic plug at the end of the handle of the art knife that can be taken out. After taking out, the old blade can be replaced with a new one.

If you look at the plug carefully, you will find a small crack in the plug. What is this for? Yes, this is what can update the old blade.

This small gap can just be inserted into the blade, and the diagonal line on the blade is reserved by the manufacturer. The stopper can break the blunt tip of the blade diagonally, and the rest can be turned into a new knife.

5. When pulling out the blade with the plug, the blade should not protrude too much, which is about the same as the position of a diagonal line, so as to avoid uneven stress and stress concentration on the diagonal line when pulling out the blade.
