Description
The utility model relates to a kind of pencil, belongs to the stationery field.
At present, pencil of the prior art, its penholder shape has two kinds: a kind of is cylindrical, another kind is positive six prismatics.The shortcoming of these two kinds of shape pencils is: in use, because finger is little with the contact-making surface of penholder, thereby the pressure that penholder acts on the finger is bigger, the easy like this middle finger muscle that causes is recessed, and can make the people that pain perception is arranged, the permanent use also can cause forming the thick callus of one deck on the middle finger, causes a kind of unnecessary damages to the people.Thereby pencil of the prior art is still satisfactory inadequately in use.
