Before the sharpener was invented, pencils were sharpened with a knife. The new invention has greatly simplified this task. With its appearance, the process has become safer and more convenient.
Variations on a theme
Sharpeners come in all sorts of shapes and colors. What manufacturers and designers just do not use to draw attention to their product. But their main difference is the type of mechanism. Today there are three options: simple or manual (the main range of the stationery market), mechanical and electric sharpener.
Work and look great
Electric pencil sharpeners have made life in the office, some homes and schools much easier when it comes to sharpening pencils. The work can be done in a much shorter time. They work from the network, batteries and even through the USB port. Their undoubted advantage is the ability to sharpen a pencil of almost any diameter.
The body is made of impact-resistant material, the blades are made of the best quality steel. The electric pencil sharpener has "auto start" options,"auto-stop", as well as the sharpening indicator. Today, Panasonic products are the most popular. They have survived use in offices and schools. Electric pencil sharpeners are functional and meet the necessary aesthetic requirements of modern institutions. The latest models are equipped with a fan to cool the mechanism and a super strong cutter for fast sharpening, an automatic switch for safe cleaning, 6 different size sections for sharpening pencils of different diameters, suction cup feet for maximum stability of the device on the table.
From history…
The first pencil sharpener was patented by French mathematician Bernard Lassimon in 1828 (French patent No. 2444). It wasn't until 1917 that electric pencil sharpeners first appeared in offices. The American writer David Reese even wrote the book "Proust from the sharpener", its meaning lies in the reasoning of how to make a business out of sharpening pencils. An entire chapter in the book is devoted to wall-mounted electric sharpeners. It turns out that there were such people in American school classes.
Choosing a sharpener
Handmade design is perfect for a child. It is safe, often has a bright children's design. For the office, of course, electric pencil sharpeners are preferable.
When buying, be sure to pay attention to the blade. It must be durable and of high quality, the best material is high-carbon steel. Poor quality blades are short-lived. The presence of a special container for chips -important detail. The absence of a waste container creates certain inconveniences when using. With electric sharpeners, you should also pay attention to the possibility of overheating and noise during operation. Some models make rather unpleasant loud sounds, which is unacceptable in the office. Trust only the best manufacturers. And then the sharpener will be not just a trinket on the desktop, but a good helper.
