Do you use different sizes of hand sewing needles, sewing machine needles, etc.?
When I first started to step on a sewing machine (when I was a student), I sewed without paying much attention to needle size, so I often experienced eye skipping and other phenomena.
Through our company’s manufacturing, we have learned that a single needle can make a difference in the quality of a product, and we are now working with a focus on needles.

In this issue, I will write about this needle, which is indispensable for manufacturing.

Needle History

Needles have a long history; needles made of bone and horn have been found among Paleolithic artifacts.

In Europe, it was even invented in Siberia 30,000 to 40,000 years ago. In China, the needle was once considered a weapon and was used as a dark instrument. It is said to have been used as a tool for assassination, hidden under a sleeve and thrown at an opponent on the spur of the moment, or as a weapon for self-defense. The needle as we know it today originated in China and came to Japan from Europe through Korea.

Circular and triangular needles


Circular needles

These needles are used to thread the thread through the holes.
The tip of the needle is rounded and will not damage the leather. Circular needles are used for sewing leather along the stitching line made by eye stitching.
