Since 1948, I.Grunwerg Ltd have proudly manufactured knives and scissors in the heart of Sheffield, the steel city and centre of cutlery production in the UK.

Whilst the factory closed in the 1970’s the business moved to Rockingham Street, where it remained until 2019, designing and supplying cutlery and kitchen knives to the consumer market.

The use of the word “Forge” is a reference to our expertise in metalware manufacturing, spanning a number of generations.

The team at Rockingham Forge have a wealth of knowledge and experience in stainless steel and knife making, that stems back to 1945.

I.Grunwerg is proud to have remained a family run business for more than 80 years, supplying the housewares industry with stainless steel kitchen products.

We don’t manufacture any more in Sheffield, but what we do is combine our knowledge of what makes a good knife with our design and marketing expertise, in order to provide good value and innovation.

Katana Saya is the universal knife brand of our times, encompassing the very best of our different cultures and traditions. 

The Katana was the prized sword of the Samurai with its extra sharp blade fashioned from folded Damascus Steel. The blades of our knives are similarly crafted from Japanese VG-10 Damascus Steel. 

The Katana was always protected inside a Sheath or Saya. We believe our knives are equally precious and deserve the same level of protection, however here we give you a choice!

For Japanese traditionalists, we present the traditional Japanese style knives with traditional Wooden Saya, to match the knife handles.

For those of a more Westernised nature we have adapted the series to represent all the popular Western-style blades and provided a more modern and practical storage solution with a real leather sheath.

The handles of our Katana Saya knives offer a further choice. Below are our different ranges:

Katana Saya Pakkawwod – Deep black elegant Pakkawood handles that give a safe grip and perfect balance.

Katana Saya Olivewood - Beautiful light olivewood handles in the traditional chestnut shape.

Katana Elements – Offered in 3 colour tones, Ocean, Rainforest or Volcanic. The handles consist of a blend of olive wood fused with vibrant translucent resins.
