Casström Lars Fält Slip Joint Knife
- Last updated: 06/05/2025
› Created in collaboration with world-renowned Swedish survivalist Lars Fält, the Casström Lars Fält Slip Joint knife is a particularly sharp and strong tool, far exceeding the normal standards of non-fixed-blade knives.
When it comes to non-locking folding knives, the most common shortfall, compared to fixed-blade alternatives, is the lack of rigidity and strength, but this slip-joint tool really bucks the trend.
Opening the knife is stiff, but not to the point of being difficult, and when the sturdy slip-joint mechanism engages, you immediately feel that the hold is strong and firm. The steel at the joint is 3mm thick and therefore provides larger bearing surfaces, which contribute to the firm hold. There is no play in the mechanism, and the knife can be used for cutting, carving, and food preparation without the mechanism slipping. Closing the knife is again stiff, but not difficult, and the blade folds away securely without any play.
Large for a folder
At 176mm long when open, this is not a small knife. The handle makes up the greater part of the length, yet remains well-proportioned and in balance with the rest of the tool. As a result, the knife feels larger in the hand and is capable of tackling much bigger tasks than you might expect.
The Scandinavian curly birch handle is large and nicely shaped to give a firm hold, and it is comfortable for extended use without any issues with your fingers getting tired or your grip slipping.
If you have large hands and avoid folding knives because they are often smaller than fixed-blade tools, then this could be the folder for you.
The blade
The 71 x 20 x 3mm thick blade is made from Alleima (formerly Sandvik) 14C28N, premium recycled Swedish stainless steel. The optimised chemistry provides a top-grade knife steel with a unique combination of excellent edge performance, high hardness, and good corrosion resistance. As with all Casström knives, the blade is cryo-quenched, which enhances wear resistance to fulfil the true potential of the steel. The steel hardness on the Rockwell C Scale is approximately 60, which is particularly hard for a knife of this style.
UK legal
The knife is designed to meet the UK legal standards for everyday carry, with a non-locking blade under 3” long. It is, of course, an individual’s responsibility to decide where, and with good reason, it is appropriate to carry a tool like this, but if you are going shooting or camping and have it with you, then you are probably good to go.
Conclusion
This is a great knife, and it sets a new standard when it comes to UK-legal everyday carry tools. With the steel being recycled and the wood coming from sustainable forestry, this knife is responsibly sourced, without any compromise on quality, so it is good for the environment in addition to being well-made. It also carries the Casström 25-year warranty for added peace of mind. GM
