The mechanical pencil "Kurutoga" series sold by Mitsubishi Pencil. The feature is that it is easier to write fine characters than conventional mechanical pencils because the core rotates little by little and keeps sharpening in a conical shape. I also use it, but its writing comfort is similar to the pleasure of "always erasing with an eraser."

From that Kurtuga, a new "Kurtoga pipe slide model" was released on November 16th. The core diameter is 0.5 mm and all three colors. The price is 450 yen (excluding tax).


The feature of this product is that the tip pipe slides in conjunction with the core, so you can continue writing characters longer than conventional products with a single knock. I would like to compare the writing comfort with the old product to see how it actually changed.

■ You can write finely even if the core does not come out!

This time, I prepared the "Kurtga pipe slide model" and the "Kurtga knurled model" that I love. Both are knock-type and are equipped with the "Kurutoga engine," which is a feature of the product.



It is also a familiar specification that you can see the rotation of the gear from the small window.


Put out the core about 1mm from the tip and try to write letters or draw lines. The conventional model became impossible to write when the core disappeared.


On the other hand, in the new model, the pipe at the tip becomes shorter as the core becomes shorter, and even if it becomes almost invisible from the tip, you can write as it is.


Of course, the Kurtuga engine continues to rotate, and the handwriting remains thin. When I was trying to find out how long I could write, the writing time was so long that I couldn't help it, and I was a little impressed by this.

When comparing mechanical pencils that do not break before, I was worried that mechanical pencils with no core would get caught depending on the paper quality, but Kurtuga reduces resistance to paper by specially processing the tip. Yes.


■ Which is easier to write?

With the addition of the function to "continue to protect" the sharp core, this product can be said to have reached a unique area. In situations where long-term writing is required, such as minutes and essays, there is no product with such few factors that hinder concentration.

However, the shorter the pipe, the harder it is to see the pen tip, so I prefer Lautrec to the ease of writing rather than durability (although newer ones should just knock on the beans). However, with the entry of the new Kurtuga, the “unbreakable mechanical pencil” market is likely to become even more exciting.
