Why do you always say that you have to sharpen a pencil with a knife when drawing?

Generally speaking, the lead core of the pencil for sketching is longer, so it is not possible to use a pencil sharpener in this regard.

Why do you have to cut it long: because you need to use a lot of lead when you draw a lot of tones, if you use a pencil sharpener to sharpen, the lead core is very short, and you have to keep cutting it, which is very troublesome and delays time, so it is best to use a utility knife to sharpen.

The tip of the pencil used for drawing does not need to be so sharp, and the shape of the pencil tip may be different depending on the technique, so the utility knife is more malleable to the tip of the pencil.

But in fact, there is no need to pay attention to the knife or the pencil knife or something, if the knife is not used to the pencil knife can also be used, but the pencil sharpener is very short and not as flexible as the knife.

In order to save trouble, you can also use a knife to cut off the wood on the pencil, and then use a pencil sharpener to sharpen the pen tip, if you knock off the wood with a pencil sharpener to cut out the nib will not be very short, you can use it.

However, it is generally recommended to use a small knife to cultivate a good feel, so that painting will also have some feeling.

Summary. Sharpening a pencil means that the pencil tip is a cylindrical shape just after being bought, and the wood wraps the lead core.

Then you need to sharpen it with a knife or pencil sharpener.

Then you can write.

Step 1: This method can sharpen the pencil that suits you according to your special needs, but this method requires a lot of experience, and the opponent's strength and skills are very high, and it is very difficult to master the method if you have not sharpened it. So let's talk about it.

Generally speaking, sketch pencils can be sharpened into square-tip pens and round-tip pens, which we will talk about separately below.

Step 2: Sharpen into a square head: This method of sharpening is relatively difficult, because it requires both a sharp and round pencil, which requires a very high level of skill, and it cannot be sharpened well without rich practical experience.

First of all, you should take a regular pencil sharpener at a 60-degree angle to the pencil, cut the wood evenly and forcefully, turn the pencil after one cut, and cut it in another part, and so on until the lead is exposed. Repeat the above action again, so that the lead exposed part of the pencil is longer, generally speaking, the exposed lead of the sketch pencil is about one centimeter, not too short, too short to be easy to use, too long is easy to break. When the lead is exposed long enough, start to cut the pencil tip with a knife, in order to cut the square head, you have to cut all four sides, you must be careful, otherwise it may break, until you are satisfied.

Step 3: Sharpen into a pointed tip: This method is relatively simple, the method is the same as the method of cutting into a square head, but when the lead is finally sharpened, it is necessary to carefully and evenly cut on each side until the pencil tip is round, and the pencil tip should pay attention to the upper thick and lower tip, so that it can be both easy to use and durable.

The first thing to do is to make sure that the pen has not been dropped. When sharpening, hold a knife in one hand and the thumb of the other hand and press it on the thumb of the knife holder. Adjust and rotate the pencil while sharpening to ensure the formation of a cone.

The length of the refill exposed is about 1 3 to cut off the wood, and in order to make the pen more usable, we can sharpen the refill into a cuboid. That is, the four drafts of the refill were flattened by Zhou. Scientifically, this refill stays sharp for a longer period of time.

Pencil (qiānbǐ, pencil), is a pen used for writing and painting sketches, which has a history of more than 400 years, among them, the pencil for painting sketches is divided into many types, it is divided into three stages of development, divided into graphite, wooden pen barrel, capped pencil; In addition, its color has red and white, black and white key Jingchun, yellow and black and other stripes.

1. It is recommended to use a hard object to make the cone surface of the pencil a little hairy, that is, to increase the friction and not slip. Remove the pencil sharpener swing hand. There must be a broken refill stuck in the knife inside, and it will be over when you pick it out.

2. If the pencil sharpener is not sharpened, it may be that it has been used for a long time, or the pencil lead has been broken in it before. It could also be that something is stuck on the turning blade. Pull it out with a needle, open it and clean it up.

The quality problem of the pencil I bought is that the lead core itself is relatively brittle. It may have been fallen, that is, after falling on the ground and shaking, it cannot be seen on the surface, but in fact, it is cracked inside.

When using a pencil sharpener to sharpen a pencil, the technique must be gentle, gently turning round and round, and not in a hurry. After turning, when taking it out, be sure to gently "pull" it out straight and parallel to the round mouth of the pencil turner. (Note:.)

When pulling out, do not lift the tip of the pen into the knife edge, because the tip of the nose is already very small at this time, and it is easy to insert it between the knife edges. )

Pencil sharpening is the act of sharpening the tip of a pencil so that it can be written.

When writing with a pencil, you need to have a sharp tip to make it easier to leave clear handwriting on the paper. However, during use, the tip of the pencil will gradually become dull and the writing will become rough, so it is necessary to sharpen the tip of the pencil with a pencil sharpener or pencil sharpener, and this process is called pencil sharpening.

Sharpening a pencil may seem simple, but it actually requires a certain amount of skill. If it is sharpened too sharply, it can easily break; If it is not sharpened enough, it will not be able to achieve the desired writing result. Therefore, when sharpening the pencil, you need to control the force and angle to keep the tip of the pencil just right.

The frequency of sharpening the pencil is also related to the individual's writing habits and the size of the handwriting, and the frequency of sharpening the pencil will be relatively higher for people who write large or heavy handwriting.
