My name is Masanori Kobayashi, and I am the CEO of Kobayashi Insulation Industry Co., Ltd., located in Oyama City, Tochigi Prefecture.
As a certified Class 1 thermal insulation technician, I have been involved in a wide range of work, including insulation, soundproofing, sheet metal construction, and the production of custom jigs.
Utility knives are commonly used on job sites, but due to safety concerns, many factories restrict their use.
To solve this inconvenience, we collaborated with skilled artisans in Seki City.
—Japan’s renowned blade-making hub
—to develop a knife that is safe to use the “KIRE Knife”.
The name "KIRE Knife" is a play on words combining "KIRE-nai " (meaning "won't cut" ) and "KIRE" (meaning "sharpness").
In other words, it cuts effectively, yet remains safe to use — that’s its greatest feature.
And that’s how the “KIRE Knife” was born.
I’ve had a deep appreciation for tools since childhood. After working at a necktie manufacturer, I joined my current company, where hands-on experience and creating my own jigs taught me the joy of craftsmanship and the importance of usability and safety.
The “KIRE Knife” is a thoughtful response to real voices from the field.
It’s more than just a tool — it’s a knife that balances sharpness and safety, making it easy and safe for anyone to use.
The design registration examination for the blade tip of the “KIRE Knife” has been finalized.
Once the prescribed registration fee is paid, the design will be officially registered and published.
