Kiritsuke Knife | "K-Tip" | Seki Collection
Fantastic multi-purpose knife with reverse-tanto blade profile. Great for most heavy tasks, the increased blade thickness lends extra strength and stiffness throughout the blade length.
Blade Length: 210mm (8.26") | Over All Length: 360mm (14.17") | Blade Thickness: 2.2mm (0.086") | Weight: 226g (7.23oz) | HRC 60-61
High carbon VG10 67 layer Damascus Japanese steel.
VG10 is renowned for its incredible edge retention, able to hold a razor sharp edge for much longer than western steels. Unlike higher carbon powder steels, VG10 has a higher amount of chromium, making it stainless.
G10 is a resin and fibreglass composite used for circuit boards and tactical gear, where it is able to withstand extreme temperatures while remaining hard-wearing.
Our Seki Collection is designed to thrive in tough environments. 'Seki' translates to 'Stone', something we felt matched the toughness of these knives. Seki is also home to a rich history of samurai sword making and more recently kitchen knife making. This collection is our small way of honouring the home of Japanese knives.

Koi knives are made by a small team passionate about what they make.
We do not have a full warranty for everything.
We make the knife and we are responsible for how the product is made. If there are any product issues related to how it’s made we take full responsibility.
Once you take the knife you are responsible for looking after it. To be clear we look at how other passionate makers work with their clients - like those who make Ferraris.
If you invest in a Ferrari you need to take care of it, wash it, service every so often. You need to treat it with love, with the same passion it was made.
If you buy a Ferrari, ignore reading the manual, drive around your local cow farm through the mud and undulating landscape. Leave it by the seaside where the salt comes in from the sea. Don’t service your car. What will happen?
Can you bring it back to the car dealership 6 months later and ask for a refund? What would they do??
We are no different. If it’s a product problem we will fix it or we will replace it at no charge. If you don’t look after your knife then it’s your responsibility. If it needs to be fixed (due to the negligence of the knife holder) then we will tell you what is costs.
Hopefully this makes sense.
Please care for your knife with the passion that your knife is made with.
A very good question. Here's a short answer.
What not to do?
Don't put it in the dishwasher or leave it in a sink full of water as this can lead to corrosion. We also recommend against cutting on a glass chopping board as this is terrible for the blade (can lead to chipping).
What to do?
Our knives have a high carbon concentration meaning they are harder at the edge. This means less honing is needed (i.e. sharpening with your rod at home or in the kitchen).
With this type of steel you should have it sharpened by a sharpener (ideally on a whetstone to stop the steel heating). How often varies depending on usage however most people do it every 3-6 months.
To summarise, less honing and more stoning.
If you need help finding a sharpener near you, give us a bell and we will do our best to assist.
Tax for Australian customers:
Australia is easy. We charge 10% GST (which is included in the price).
Tax for overseas customers:
Rest of the world is a little more complicated. To date, we have experienced very few tax issues at customs however we're happy to talk with you if you're unsure (and we can pass on what has happened for knives sent to the same region in the past).
Buy it with
An edge in the kitchen
Edge retention is crucial for keeping your knives razor sharp. We choose rock-hard steel at 60-61HRC to ensure your edge is Hattori Hanzō sharp out of the box, and keeps its edge for much longer than other knives.
Quality Japanese Engineering
Our blades are forged in Japan by Aichi Steel. We select AUS10 steel for its high carbon content, corrosion resistance and quenched hardness. This results in a knife with incredible sharpness, balance and toughness.
Insatiable foragers and tinkerers
We gather symbolic and interesting woods from our surroundings to make unique handles. Each piece carries a story and origin, set into coloured resin to create functional art in your kitchen.
