Kasperi Fold Top from whitetail deer leather

Kasperi’s Fold Top is a product that lasts a lifetime, it is an investment that only gets better, more sustainable, and affordable with time. Stylish for city use. Sturdy for the forests. The ergonomics of the bag are designed to stay comfortable even after whole days carrying heavier loads, and in addition it has six external attachment points for your Roselli equipment.

The Fold Top included in The Explorer Set Mk II might just be the last backpack you’ll ever need. It’s made from premium ecological whitetail leather (learn more here) custom-developed for Kasperi. Using the whitetail also makes use of a material that would otherwise be doomed for waste.

Kasperi Puukko – The original multitool crafted by Roselli

Designed by Kasperi and handcrafted by us at Roselli, the Kasperi Puukko is a take on the quintessential Finnish puukko. The puukko is a utilitarian type of knife made for handling a large variety of tasks. 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 making fire, carving, making shelters for the night, preparing a meal and eating. The Kasperi Puukko is made to cultivate these wilderness skills.

The shaped handle is made out of stained 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 makes it handle rougher tasks with ease. Roselli's signature Ultra High Carbon steel keeps the edge like no other. Kasperi custom 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.

Roselli axe, short stained birch handle and Kasperi custom axe sheath

Roselli's traditional Axe with a shorter handle is an effective wood cutting tool, whether used while camping or at the summer cottage. The wide blade angle prevents the axe from getting stuck, and in addition to woodcutting, it can be used for whittling as well. This special edition comes with a Kasperi custom made Cognac-brown German SOHRE Tanneries vegetable tanned leather sheath to protect the edge. With the two supplied Kasperi utility straps, you can attach the axe to Kasperi Fold Top-backpack. The axe handle is made from birch and is stained and coated with linseed oil to ensure a firm grip, even when wet.

Roselli Firesteel, stained curly birch handle

In The Explorer Set Mk II we’ve also included a custom firesteel. A firesteel is a tool with which you can create sparks. It comes incredibly handy when you want to start a fire, and is, therefore, a self-evident tool to carry with you. The Roselli 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. The Roselli Firesteel attaches to the Kasperi custom made knife sheath.
