Adachi Tool Store’s carabiner is made by bending a palm-sized flat bar beautifully and maintaining its shape only with the elasticity of the metal.
We believe that its simplicity makes it possible to use it for a long time without getting tired of it.
Also, although it looks simple
It is filled with the wisdom and ingenuity of craftsmen who are well versed in the characteristics of metal.
It is manufactured by Iwaki Kogyo, a wire rod processing company that has been in business for 58 years.
It is a town factory that specializes in bending and welding bar-shaped metal.
Stainless steel has a slight bounce from the angle at which it is bent, and they bend it more than the angle at which they want to bend it.
If that angle is too shallow, the carabiner will be too hard to use and lose its shape.
Conversely, if the angle is too deep, the carabiner will not hold and will not be able to hold key chains or other items in a bundle.
Iwaki Kogyo’s skilled craftsmen were able to create the shape of the carabiner through repeated prototyping based on the thickness and width of the stainless steel.
This carabiner was made simple by the skill of the craftsmen.
