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.

Katana Pearl – Feature a stunning iridescent abalone effect handle.

Katana Tiger – Offer a striking tiger print design to bring a touch of the wild into your kitchen.
