How It Started

Made to Elevate Everyday Cooking

Katana Saya was founded with a simple idea: exceptional kitchen knives should be both beautiful and practical.

Too often, home cooks must choose between affordable knives that lack performance and style or professional tools that feel intimidating or out of reach.

We set out to bridge that gap by creating Japanese-inspired kitchen knives that deliver outstanding quality, refined aesthetics and lasting value to elevate everyday cooking.

Our Journey

Our Story

Katana Saya is a brand by Grunwerg, a family business founded in 1945 in Sheffield. A British design led business still based in the Steel City, over the course of the last 80 years Grunwerg has become a successful manufacturer and designer of knives and cutlery. We pride ourselves in creating products that not only last the test of time but enable you to ‘Live Beautifully’.

Japanese design has long celebrated the beauty of simplicity, precision and intentional craftsmanship. These principles influence everything we do. From clean, understated lines, to carefully considered balance and ergonomics, our knives embody a design philosophy where every detail serves a purpose.

Our Design

Every Katana Saya knife is designed to bring together exceptional performance, enduring craftsmanship and timeless aesthetics. At its core is a precision-forged VG-10 Damascus steel blade, chosen for its outstanding sharpness, edge retention and distinctive layered finish.

Inspired by the legendary katana, the prized sword of the Samurai, renowned for its remarkable strength and razor-sharp blade fashioned from folded Damascus steel.

Our blades pay homage to this ancient craftsmanship while embracing modern manufacturing techniques. Each knife is paired with a handle that celebrates the beauty of the natural world.

Our Packaging

Completing every knife is a protective saya – a modern interpretation of the traditional sheath that safeguarded the Samurai’s katana.

We believe our finely crafted knives are equally precious and deserve the same level of protection with a wooden or leather sheath and a luxury wooden gift box.
