Casström No.8 SFK - Compact Scandinavian Utility Knife for the Outdoors.
Don't let its size fool you - the Casström No.8 SFK is truly a "Little Big Knife". A small knife with big capabilities. Inspired by the rugged versatility of the popular No.10 SFK and a few centuries of Scandinavian utility knives, this compact fixed blade is purpose built for serious bushcraft, hunting, and outdoor use.
Designed with precision and crafted for everyday performance, The No.8 SFK excels in wood carving, making feathersticks, food prep and other camp tasks. Lightweight yet tough, it's the ideal companion for minimalist adventurers, preppers, and outdoor enthusiasts who value compactness and power.
Key Features
Perfectly balanced design: The 8cm long and 2.8mm thick blade is tailored for those who appreciate a knife that is just the right size for close work like whittling and woodcarving and food prep. Its ergonomic handle, complete with a reassuring finger groove, offers a secure and comfortable grip.
Versatile and comfortable: Whether you have large or small hands, the No.8 SFK fits comfortably, allowing for precise control. The knife is the ideal size for safely “choking up” on the blade for finer wood carving tasks.
Superior Blade Spec: Made from Alleima (formerly Sandvik) 14C28N, a recycled Swedish stainless steel. The optimized chemistry provides a top-grade knife steel with a unique combination of excellent edge performance, high hardness, and good corrosion resistance as well as ease of sharpening. Casström blades are all cryo-quenched as standard too, which enhances wear resistance and fulfils the true potential of the steel.
Wilderness reliability: The scandi grind, and full-tang construction help make the blade both stable and robust, even under demanding conditions. Even in the event of a handle break, a full-tang knife can still be easily used. The scandi grind is perfect for carving wood.
Bushcraft Ready: On its own or paired with an axe or larger blade, the No.8 SFK completes your essential bushcraft tool combination. Its lightweight design makes it an excellent belt knife, or a more specific game prep or fishing knife.
Premium Handle Options: Choose between the elegant beauty of hand-finished Scandinavian Curly Birch or the weather resistance of tough Green Micarta – both paired with our vegetable-tanned European Leather Sheath with the stylish Casström Leaf emblem on the front face.
Firesteel Option:For those who need the ultimate survival tool, this model includes our fantastic 12,000+ strike Auermetall Fire Steel (with matching handle of curly birch), and a leather sheath with integral fire steel loop. Firelighting has never been this easy!

Perfect companion to a 10
If you have a 10 you need an 8 and if they ever bring out a bird/small game and a fillet knife its all you would ever need.
Those 4 knives would do all your meat processing.
I can and have made many knife blades but i cant make a blade better than Casstrom .
And not for the money.So why bother.
And boy do they last and take some hammer.
I shoot a deer a week(also many bunnies and duck/goose) and 3 years down the line my 10 is like new.
You cannot beat Casstrom blades ,don't fall for silly price,s ive done it there is no better blade just more expensive.
The No8 is superb.
Bring on the Fillet and trout&game PLEASE.

I bought the Mk1 blade and drilled out the holes to 5mm. Finished with some spare ply offcuts and 5mm aluminium pins. Very pleased with this. I now have a decent field saw for the fraction of the price a complete one would have cost.
Very pleased.
Blade just as discribed some trouble with delivery but resolved quickly and resent via Royal Mail no problems
In the process of creating a Thuya Burl handle 👍🏼

The best U.K. legal knife money can buy
I purchased the Lars Fält slip joint knife from Casstrom at the bushcraft show almost a year ago now. Having used this knife on a weekly basis I am confident in saying this is probably the best U.K. legal slip joint money can by. As always the knife scales are finished beautiful curly birch. I would recommend regular oiling with boiled linseed oil if you use it frequently. The steel is perfect for every day, low maintained use. Holds an edge relatively well and is extremely easy to sharpen. What sets this knife apart from the competition, is the folding mechanism, unlike almost all folding knives, the blade on this mechanism stops at 90 degrees, adding that extra security to a folding knife. This has saved my fingers on more than one occasion, this is very well designed. I’d recommend this over any other slip joint on the market! Well done Casstrom 10/10

Another excellent purchase from Casstrom. Received this one as a birthday gift. Leo went above and beyond to ensure we could get the knife engraved with custom text. As always excellent build quality by Casstrom. Sturdy sheath of good quality leather. Razor sharp out the box, haven’t needed to sharpen it yet but sure it will be as easy to sharpen as my other Casstrom knives. Fire steel is a lot thicker than I expected and should last a long time.

Impeccable customer service
I'll start with the knife. It's beautiful and highly functional. I'm mostly using it for skinning wild boar just now and it's lovely to work with. The handle fits numerous different grips really well and I didn't find it getting too slippery with a bit of claret on it which was a nice surprise. The blade is relatively easy to get a razor edge on and seams to keep it really well even when you're taking the feet and head off.
Now the customer service, I was truly gob smacked how good it was. About a day or two after I'd placed my order I received a phone call from Sweden from a lovely English bloke (sorry I didn't get your name) saying one of my items was out of stock in the UK distribution centre so he'd ship from Sweden if that was okay and if I wanted to change my order to get an all black setup he could sort that out. I was almost speechless but managed a 'hell yeah'. So I got more than I had expected delivered faster. How often does that happen. I'll be recommending Casstrom to everyone at the hunt from now on.
No.10 Swedish Forest Knife - KYDEX SHEATH

Useful accessory
I already have one of these danglers for my RM bushcraft knife, but I wanted to modify the leather sheath for my Fallkniven A1 Pro to make it quick release. I removed the old belt attachment and rivet, fitted the dangler attachment and replaced the sheath rivet with a Chicago screw. It makes the whole thing much more user friendly, I don’t know why Fallkniven don’t fit these as standard.
