Sanjo City, Niigata Prefecture, is said to be a mecca for metal processing such as knives and tools, and is also famous in Japan as a ``blacksmith town.''
Top Kogyo, which has a history of 80 years as a long-established tool manufacturer in such a historic town, has planned and developed an original brand for users who want to make more beautiful accessories.
That is the high-class tool that we will be introducing today."KUROBISAI" is.
``KUROBISAI'' was produced based on the knowledge and technology cultivated over many years of tool manufacturing.Kurobisai was designed and developed by female staff as a high-performance tool that fulfills its role at a high level, with the ``better tools'' demanded by users when making accessories, not just the technology, but the comfort of ``taking the place of your hands'', the feminine design, and the sense of size.
Once you use it, the ease of use is obvious.
Each movement, such as opening and closing the can or cutting with the nippers, is very light.
You'll be surprised at how much easier and less forceful you can work with this tool compared to conventional tools.
12 different tools that will take your production to the next level.
Please find the tool that suits you from among the unique features of each tool.

Features

Make ``creation'' comfortable. A pleasant ``joy''. In your hands as you create beautiful things, your feelings will bloom.With the motto of high quality and beautiful design, our tools are created using the advanced skills of craftsmen. We will introduce the common features of each tool that incorporates user requests and focuses on ``ease of use'' and ``less fatigue.''
[KUROBISAI Features]
・Smooth finish due to "barrel polishing" of metal parts
- Made of stainless steel for a sophisticated and easy-to-use feel and ease of maintenance
・Smooth movement of the opening/closing part by using a "set pin"
・Pursuing a grip that makes it easy to apply force evenly and is comfortable for women's hands
・The spring part is designed so that it does not get tiring even after repeated use, and can be replaced.

Smooth finish by barrel polishing
The "barrel polishing" developed through metal processing provides an exceptionally smooth surface.
Creating with beautiful tools also improves the level of completion, as the parts themselves are less likely to get scratched when you touch them during work.
Easy to use due to stainless steel
The main body is made of stainless steel, which is resistant to rust and prevents metal allergies. It is also a material with excellent wear resistance.
Being made of stainless steel allows for precise and precise shapes to be created during manufacturing.
There is no special need for oil to prevent rust or to open and close the door, but regular maintenance will ensure that it can be used beautifully for a longer period of time.
Smooth opening and closing due to the use of set pins
In pursuit of ease of use, KUROBISAI uses a "set pin method" for the screws that control opening and closing.
The "set pin method" allows for appropriate adjustment of gaps between parts without deformation or impact during manufacturing, resulting in smooth movement and precise operation.
About the smoothness of opening and closing
An illustrated comparison of the "set pin method" and "rivet method".
Tool operation that is too heavy or too light will lead to wear and tear on parts. The set pin method makes it easy to adjust to just the right fixation, reducing factors that cause premature wear and creating a structure that makes it easy to create smooth movement.

Commitment to grip
In pursuit of a grip that fits comfortably in your hand and is easy to handle, we have created it through repeated prototyping and testing.
This attention to detail is evident in every detail, including the shape of the grip to evenly transmit force to the tip of the tool, the textured finish that makes it easy to hold, and the structural design to prevent the grip from wobbling or the tool from falling out due to long-term use.
A “sustainable” spring that can withstand continuous use
The spring part that supports movement when gripping uses a torsion coil spring. The tip can be opened and closed easily, so you won't get tired even when working continuously for long periods of time.
A structure that reduces metal fatigue and improves durability. If the spring breaks due to long-term use, you can easily replace the spring. In that it is a tool that can be used for a long time by replacing parts, it can be said to be a product that incorporates the current "sustainable" spirit.
This video explains how to replace the springs.
