Puukko – w/ Firesteel BLACK

Regular price €360,00

This is our take on the quintessential Finnish puukko, a utilitarian knife made for handling a large variety of tasks.

At Kasperi we believe the things we produce should last for life. Items should cultivate a special connection with their users. After the popular collaboration in 2020 with Roselli - we came together to create the second edition of the Explorer Set.

In our 2022 collaboration, we created the Kasperi Puukko, our vision of the quintessential Finnish utility knife paired with a Firesteel, crafted by Roselli. Now in black leather!

For Finns the puukko is the original multitool. The skill of using a puukko in versatile ways safely is not only useful but also a great source of joy. In Finnish tradition, the puukko is used for absolutely everything. It was used for preparing a fire, carving, making shelters for the night, preparing a meal, and eating. The Kasperi Puukko is made to cultivate these wilderness skills.


Puukko – the Original Multitool

  • The shaped handle is made out of curly birch and treated with linseed oil for a firm grip even when wet.
  • The burly 4 mm thick blade and the full tang structure make this knife uniquely equipped to handle rougher tasks with ease.
  • Roselli's signature Ultra High Carbon steel keeps the edge sharp like no other.
  • Our tailored sheath made out of vegetable-tanned leather protects the blade and lets you hang the Puukko safely on your belt.
  • The Firesteel that’s housed on the sheath makes the Kasperi Puukko a valuable tool for creating a fire.

Usage instructions

How to make a fire with the Roselli Firesteel

The Firesteel is housed in the tailored sheath along with the Puukko. The firesteel is a tool with which you can create sparks for creating a fire. The firesteel is used with the backside of the knife to strike sparks on a prepared “primer” tinder - for example, dry birch bark that is rasped with a knife to create a flammable kindling. Once you get the kindling ignited, it is gradually fed with larger sticks until you have a campfire.

How to take good care of your Puukko to make it last for life?

UHC steel offers unparalleled blade performance, yet this also means that the blade should be handled with care. The hardness of the steel means that small rocks in between the blade and wood can cause blade edge damage. Edge damage can be refurbished easily by a knife smith or by sending the knife to Roselli's included lifetime sharpening service. Therefore we recommend that when batoning (splitting wood with the knife), take care that you always use the knife on the clean side of the log and take care to not drop the knife on rocks or other hard surfaces. For corrosion protection rinsing the blade from any saltwater, then drying and oiling the blade is the best practice. By keeping your blade clean and oiled, you'll make sure the blade will stay sharp and strong for ages.

This product includes Roselli's lifetime sharpening service. So in case your blade needs refurbishing, just ship the product, and Roselli will take care of it!

Purchased to complement my black fold top and kuksa.

The puukko feels very heavy-duty yet has a nice balance. The tailored sheath is just that, tailored, meaning that it fits (and looks!) perfectly. If I were pressed to find a "fault" with this very smart-looking and well-performing knife, I would point to the colour of the handle which is more grey than black. Nevertheless, this is a minor gripe as overall I am more than pleased with this very handsome and functional tool!
