Born from a 70-year-old Japanese stationery company, Ohto created the CLO-500 to solve a common frustration: metal letter openers that rust, stain, and fail. Our engineers in Tokyo turned to advanced zirconia ceramic, a material trusted in medical scalpels for its permanent sharpness and complete inertness. Every component is sourced and assembled in Japan under strict manufacturing oversight, ensuring a tool that performs flawlessly from the first use. This commitment to solving a simple problem with over-engineered precision has made it a top-ranked and award-winning opener in its category, trusted by offices and homes that value lasting performance over disposable tools.

The Ohto Ceramic Letter Opener CLO-500 is crafted from high-quality ceramic, specifically zirconia ceramic, which serves as the primary material for the blade. This ceramic is chosen for its exceptional hardness and durability, making it highly resistant to rust and corrosion, a key feature that ensures longevity and low maintenance. The handle is typically constructed from stainless steel or a similar metal alloy, providing a sturdy and ergonomic grip that enhances user comfort and control during use. The inclusion of ceramic in the blade offers a sharp, precise cutting edge that glides smoothly through paper without tearing or snagging, while its rust-proof properties eliminate the need for oiling or special care, making it ideal for humid environments or long-term storage. Together, these materials embody Japanese craftsmanship by delivering a reliable, efficient tool that combines aesthetic appeal with practical benefits, such as reduced wear and enhanced safety due to the non-conductive nature of ceramic.
