Tsushima Ocean Knife

Where tradition meets innovation—
The SUSTAINABLE KNIVES COLLECTION embodies a future-oriented approach to Japanese knife-making that embraces environmental responsibility.
With initiatives like the Tsushima Ocean Knife, which repurposes ocean plastic, we’ve infused each blade with a conscious choice to live in harmony with the Earth.

At MUSASHI, our product concept is simple yet profound:
To transform discarded plastic into objects so meaningful and beautiful, they will never be discarded again.
Through traditional craftsmanship and modern design, we give new life to what was once waste—turning marine debris into tools of purpose and artistry.

To cut is to shape. And now, with MUSASHI JAPAN, every cut carries the power to shape a better future.
