My interest in knives are primarily the technical aspect with focus on functionality and mechanical properties as toughness and wear resistance. To achieve excellence in my knives I use the optimum materials for knives available today, and I have access to heat treatment practices unavailable for most knifemakers.

My background as a metallurgist gives me an understanding of materials beyond that of most. This is a great resource in most parts of knife making, especially in material selection and heat treatment. There is a vast number of steels on the marked, and those considered the best are in most cases not. To evaluate and choose materials you have to understand how the steel is affected by the composition and heat treatment.

SEAL prototype

Pictures of one of the first SEAL prototypes during testing in the jungles of Borneo. The handle is black micarta and the kydex sheath made especially for diving. Paracord and tape added by the customer.


The Seal is a larger field and dive knife with a hidden tang like the Hassel. It has a blade length of 155 mm and a total length of 275 mm. The blade is 5 mm thick and in A8-mod hardened to 61 HRC. The handle on this knife is black G-10. The tang is 20 mm wide, except the last 15 mm, and protrudes from the back of the handle. It comes with a kydex or nylon sheath.

Hassel V2

Identical to the Hassel, but with a high "saber" grind and small swedge similar to the Survival, instead of a full fat grind. The blade is 11 cm long, 5 mm thick and in A8-mod. The handle is green canvas micarta, but G-10 is also an option. The hidden tang is fixed with a tube, which also will be the case with the regular Hassel from now on.

Chopper V2

This is a lighter version of the chopper that combines good cutting ability and light weight. The blade is 25 cm (10 inches) long and 5 mm (0.2 inches) thick, and total length is 38 cm (15 inches). It’s made of A8-mod. Available with micarta or G-10 handle.

Field kit

Unlike common survival kits this kit contains high-end components that can last a long time in the field, and is intended for hard use. It consists of:
- Custom size, medium Spyderco ceramic hone in rubber tube, approximately 100 mm x 25 mm x 12 mm.
- Maratac Screwkey, phillips and straight, with stainless 34 mm McGizmo clip.
- SERE compass, a dry, brass compass with a diameter of 25 mm with a braided nylon line.
- Light My Fire FireSteel Army with 40 cm 550 FireCord and stainless 34 mm McGizmo clip.
- Fatwood to be used as tinder.
- Steel tin, 108 mm x 79 mm x 25 mm.
In addition to protection, the rubber tube the hone is supplied in can be used as underlay when using the hone on a flat surface to increase the friction. The nails is to support the hone on a rougher wooden surface, like a log. The stone is used dry to save time and water compared with water stones. The McGizmo clips are intended to secure keys and FireSteel in the pocket.


This knife was originally designed and made by Kaj Embretsen as a collaboration with Lars Fält for Svenska Överlevnadsenheten (The Swedish military survival unit), and the knives have mainly been available for this unit. It’s often referred to as a “Lars Fält knife” in the bushcraft community.
I wanted to make this knife more readily available and also add it to my line up due to its mild appearance, but still being a very rugged construction and functional design. I have gotten both Kaj Embretsen and Lars Fälts approval to make and sell this knife.
The original knives were made in SS1778, but to increase the toughness even more and still keep similar properties I selected AISI L6 for my version. The OA length is 22 cm, the blade length is 10,5 cm and the thickness is 5 mm. It comes with Turbax handle and a kydex sheath.
