Puna Knife by 3COIL
The “Puna” is a knife designed for the modern world. Beautifully designed, meticulously engineered and exceptionally flexible, the “Puna” is your perfect everyday carry tool. Not only does it look amazing, it is extremely tough, and will withstand years of use.
What we do
Our mission, based in our London headquarters, is to design high-quality knives. Whilst small and discreet, our knives are incredibly useful around the studio. Our blades are sharp – surgically sharp – but when the blade does eventually go blunt, it can be replaced in just seconds.
The “Crane” was the first knife we made, and it proved so useful in our day-to-day lives, we never left home without it. We thought that its small size would mean it would only be used as an emergency back-up, but the more we used it, the more we realised its small size was its main strength – and it is now our ‘go to’ tool for all jobs requiring a sharp edge.
What is the “Puna”?
Once removed, the knife fits snugly in your hand. Its unique design pulls the blade securely under your finger, giving you unbelievable control. It really is the perfect precision cutting tool.
Changing blades on a traditional scalpel is dangerous – if not impossible – without the correct tools. The Puna’s discretely hidden ‘micro screwdriver’ is a dedicated tool for maintaining the knife. Simply remove two screws and swap out the blades in a simple and safe way, without the need for any additional (and unnecessary) tools.
All our knives fold or unclip, which ensures they remain safe in your pocket, unlike the standard scalpel blade pictured above. These blades can be dangerous as they are always exposed, and there is no elegant way to carry it. 3 Coil knives, on the other hard, were created with safety and portability in mind.
Also hiding in plain sight is a bottle opener. We’ll let you into a little secret here – this feature actually came about by accident. We noticed that the shape of the stock and grip made the perfect opener, and no multi-tool would be complete without an emergency beer opener!

Why we like scalpel blades
As well as being razor sharp and easy to change, the Puna has another huge advantage over all other knives. Most of us have been in a situation where we have arrived at an airport, forgetting the sharp object at the bottom of our bag – with the Puna, you can just detach and dispose of the blade and buy a new one when you land, without having to throw away your precious knife.
What is the Crane Knife?
The Crane, we are proud to say, is the smallest folding scalpel blade in the world. Keeping a blade sharp can be a real challenge, and depending on the knife this can also require a lot of skill. This is why we love scalpel blades for day-to-day use. Since a blunt knife is more dangerous than a sharp one, it is important that as soon as a blade shows signs of dullness, it is replaced with a razor sharp new one.
Normally we custom-make Crane knives in very small numbers, but now it is time for you and the rest of the world to get your hands on one. For the first time ever, we will produce a production run of our famous Crane knife. Whether you are an artist, an architect, a designer, or just someone who likes opening boxes, the Crane knife is the smallest, simplest and sharpest knife you can carry. For our first production run, the Crane will be crafted from stainless steel, and be available only in silver.

Building the Puna Knife
The Puna is made from stainless steel. As the 3D render shows, it needs a lot of tooling and tiny moulds. It is no surprise we have spent over 18 months designing and testing many different prototypes, to make sure we got just what we wanted. We didn’t just want to build a beautiful desk toy: we wanted something which worked as well as it looked. After an exhaustive process talking to manufacturers who could match our eye for detail and create what we wanted, we found one who can help us mass produce our beautiful designs. With your help and support, we can bring this knife into production for the whole world to enjoy.

Risks and challenges
We know from experience that choosing the right manufacturing partner is key to any successful project. That is why we did not rush this stage, and we delayed launching for many months until we found the perfect factory who understood our level of quality and finish. Our factory has been building multi tools for nearly 15 years. With our creative skills and their expert knowledge in manufacturing we are confident we will not run into any big problems. Obviously we expect to run into challenges along the way, but we have an amazing team in place that are experts in all areas of the production process - from design to shipping and customs.
We will be shipping at the end of June 2018 - We plan to place the manufacturing order in Feb 2018. We will iterate, review samples and do quality control in the beginning of March, and by the end April 2018 we expect to get the first shipment in from the factory. May 2018 we will be putting the finishing touches to our exclusive presentation case which we are building in house. We don't anticipate any issues currently with this timeline. However, if by chance anything unexpected happens, we promise to keep you informed, both during the campaign and afterward.Learn about accountability on Kickstarter
