Keke:"Pupu, hurry up! Art class will be late!"

Pupu:"Wait, my art knife is blunt. I need to borrow one from other students."

What if the art knife becomes blunt?

Students who often use the art knife will find that after using the art knife for a long time, the blade will naturally become less sharp due to excessive wear, which will greatly affect the use efficiency. But don't throw it at this time! Because it still has the opportunity to be renovated!

Take up the art knife in your hand and observe whether the buckle at the end of the art knife can be removed? Are there many obvious diagonal creases on the blade of the art knife? If the above conditions are met, congratulations on getting a new art knife!

How to replace the blade?

The first step is to remove the buckle at the end of the art knife, which can be used to break the blade later to prevent skin scratches.

The second step is to push the art knife upward for 1~2 distances. Note: the knife edge must be aligned with the crease or gap, otherwise it is easy to damage itself or the blade.

Then we turn the whole blade face upside down (eyes facing the back of the blade), so it is not easy to hurt ourselves when we break it.

Finally, take the buckle removed in the first step, hold the blade outside the knife edge, and break it.
