I am a post-70s generation, and I remember that in our time, when I was in elementary school, the variety of pencil sharpeners was far less abundant and high-end and humane than it is now. At that time, we used a variety of pencil sharpeners, including store-bought pencil sharpeners, single-edged blades, and even blades used by my father to shave (when I used it, I broke it in half, and the whole blade was very easy to hurt my hands), and even found a hacksaw blade by myself, and then sharpened it on a whetstone。

I still remember when I was in elementary school, we had to put a lot of effort into sharpening the pencil before each homework. At that time, most of the pencils we used were wooden, and we had never seen a mechanical pencil today. First of all, you need to use a blade or pencil sharpener to cut the wooden part of the pencil into a conical shape, and then slowly scrape the tip of the pen to make it easier to write. Sometimes, sharpening a pencil becomes a daunting task because the pencil sharpener is not sharp enough. In order to sharpen the pencil, we often need to scrape repeatedly, which is not only time-consuming and laborious, but also easy to get our hands full of sawdust.

Later, there was a very simple pencil sharpener on the market, which was shaped like a small horn, and we could sharpen a beautiful cone by simply putting the pencil into the mouth of the pencil sharpener and turning the pencil slightly. Don't underestimate this pencil sharpener is very simple, but it is very practical and safe to not hurt your hands, because sharpening pencils with a knife or blade is commonplace. This pencil sharpener became one of the most popular pencil sharpeners when we were children.
But he still has a disadvantage, that is, the blade is not sharp after a long time, so it often breaks the nib, at this time we usually unscrew the screw that fixes the blade, and then take off the blade and grind it on the whetstone, sharpen the blade and install it, so that it can be used for a long time.
This was the highest level of the year
With the development of the times, children's pencil sharpeners are also constantly upgrading. Today's children, their pencil sharpeners are not only varied, but also more and more intelligent. Some pencil sharpeners can automatically adjust the thickness of the nib, and some pencil sharpeners also come with a pencil scrap storage box for easy cleaning. There are even some pencil sharpeners that can be connected with a mobile phone to control the working mode of the pencil sharpener through the mobile phone APP.
In addition to traditional manual pencil sharpeners, there are now a variety of pencil sharpeners such as electric pencil sharpeners and hand-cranked pencil sharpeners. These modern pencil sharpeners are not only convenient and fast, but also have beautiful designs, making them a good helper for children to learn and Xi life.
Looking at the various high-tech pencil sharpeners used by children today, I can't help but sigh at the changes of the times. Recalling the simple pencil sharpeners we used when we were children, although full of memories, it also made me feel the convenience brought to our lives by the progress of science and technology.
The change of the pencil sharpener is only a microcosm of the development of the times. In this era of rapid technological change, the power of technology can be felt everywhere in our lives. It not only changes the way we live, but also makes our lives more convenient and beautiful.
However, while enjoying the convenience brought by technology, we must not forget those simple and beautiful memories. The pencil sharpeners that once accompanied us in our growth have gradually been phased out, but they have forever remained in our memories and become a good memory of our childhood.
Perhaps, one day in the future, our children will be like us, recalling the pencil sharpeners they used when they were children, and feeling the innocence and beauty. And this is the precious gift brought to us by the changes of the times.
