We are very particular about the finish of our products.

Especially, the tip of the screw is finished by “hot forging.”
“Hot forging” is a technology used to process materials by applying heat and beating them.

It is a technique that is based on the manufacturing process of the Japanese swords “Katana,” which is the masterpiece of forged products that Japan is proud of in front of the world.

Although it is more time-consuming than other methods, it does not destroy the structure of the material and enables a smooth finish.

We have evolved this traditional “hot forging” process in our own unique way and realized a fully automated process, which is rare in the industry.

More than 40 years have passed since the first automation. We continue to make improvements and evolve our forging technology, which is the pride of Japan, to suit the needs of our drivers.

Although it takes time to complete a single driver, this manufacturing method results in highly accurate drivers.

Quality inspection is the last stronghold in the manufacturing process.
In this process, we are very particular about the inspection of all products.

We have our own standards for all items in each process, not to mention the precision of the tip and the appearance of the product—and we inspect all products.

“Can’t tell just by looking at it.”
“Can’t tell until you use it.”

You can’t tell until you use it.

That is why we inspect our products to ensure that they strictly adhere to our own standards.

As a result, our screwdrivers are strong enough to withstand symptoms such as cracking and discoloration and can be used semi-permanently.

We provide satisfactory, Japanese quality to the whole world.
With this aspiration in mind, we conduct inspections on a daily basis.
