【 ホッチキス・hotchikisu 】stapler
A stapler in Japanese is called ホッチキス or ホチキス (hochikisu).
The onomatopoeia for the latching or clamping sound of a stapler is ガッチャン (gatchan). For this, some people in the northern part of Japan call the stapler ガッチャンコ.
On the other hand, some call it a ジョイント (jointo), which is easy to imagine how it came about.
So why is it called a ホッチキス?
