Birds. Fish. Animals.
Three more collections from Koi — one for the pocket, one for the dock, one for the fire. Named for the country, designed in South Australia.
01
Pocket Knives
The Aviary.
Australian birds, forged into pocket knives. From the Magpie to the Bowerbird — 22 blades for the everyday carry.
Shop the Aviary →
02
Fillet Knives
The Tide.
Australian fish, forged into fillet knives. 85% of us live on the coast — these are the tools for what comes out of it.

03
Fire & Outdoor
The Wild.
Australian wildlife, forged into tools for the fire and the field. From the Brolga to the boning knife — nose to tail, paddock to plate.

Where Koi began
Two cities. One beginning.
Before the rivers and the wildlife, there were two Japanese cities — and the space between them is where Koi was born.
Osaka
Colour · Style · Energy
Three words carry Osaka: colour, style, energy. The brightest, boldest knives we make — pattern and life in every handle. Osaka is Koi with the volume up.
Shop Osaka →
Kyoto
Stillness · Craft
Kyoto is the quiet half — minimalist, restrained, considered. It's the city that taught our family about Japanese style and art, and it holds a family story we hold close.
Shop Kyoto →Osaka's colour. Kyoto's calm. Every Koi knife since has lived somewhere between the two.
The Long Lunch
Where the country comes to the table.
Serving and sharing tools named for Australia's great wine regions. It opens with the McLaren Vale waiter's friend — and runs the length of the meal.
Explore the collection →Sharpening
Keep every edge as sharp as the forge intended.
A Koi knife is made to be sharpened, not replaced. Bring yours back to a keen edge with our sharpening service, learn the craft in a hands-on class, or take home the tools to do it yourself.
Sharpening Service
No appointment needed — just drop your knives at the workshop. We'll even lend you one to use while yours is being sharpened, free of charge.
Find the workshop →Sharpening Classes
Hands-on workshops for home cooks and pros alike. Learn to read a blade and keep your own edge sharp for good.
See class dates →Sharpening Tools
Whetstones, strops and honing gear, chosen by us — everything you need to maintain a fine edge at home.
