The "pencil breakage protection mechanism" works effectively only when the pencil is not extended from the tip.
Body dimensions 14.6 x 10.7 x 143 mm / weight 12 g.
The ability to write beautiful letters is considered an important function for a pencil sharpener, primarily for middle and high school students who use the pencil sharpener daily for learning.
The mechanism that rotates the pencil twice as fast allows you to continue writing beautiful letters without changing the darkness or thickness.
The automatic pencil rotation mechanism "Kurutoga Engine" of the "Kurutoga Standard Model" uses a 40-tooth gear, so the pencil rotates once every 40 strokes. The automatic pencil rotation mechanism of the "Advance" is equipped with "W Speed Engine," which uses a 20-tooth gear that rotates twice as fast, allowing the pencil to rotate once every 20 strokes. By changing the gear of this automatic pencil rotation mechanism, it is now possible to continuously draw lines that are approximately 12% thinner with HB and about 17% thinner with 2B.
The precisely machined parts suppress the vibration of the pen tip, which is unique to Kurutoga, for a stable writing feel. The automatic pencil rotation mechanism rotates the pencil every time you write, so the gear moves up and down every time the pencil tip leaves the paper.
By constructing the ferrule, which is one of the parts of the tip, from precisely machined metal, vibration is suppressed, and the writing feel is stable.
The pencil breakage protection mechanism makes it difficult to break the pencil, allowing you to concentrate. The sliding tube, which allows you to write without having to extend the pencil tip from the tip tube, prevents pencil breakage while writing.
