I decided to pair up a fixed blade and folder for this detailed review; the Casström No. 14 SFK and Casstrom Lars Fält Slip Joint. The No.14 is a new knife designed by Casström to tackle the toughest challenges nature throws your way. Built for rugged outdoor use, bushcrafting, survival skills training, or hunting. With its full-tang construction, the No.14 SFK’s large blade is great for those bigger more demanding jobs, like splitting wood but also just as happy carving too. This example features green Linen Micarta handles and A8Mod steel, and is supplied with a vegetable-tanned leather sheath.
The Casström Lars Falt Slip Joint was created in collaboration with world-renowned Swedish survivalist Lars Fält, and was designed to meet UK EDC legal requirements by virtue of having a non-locking folding blade under 3 inches with a sturdy opening and closing mechanism. The handle is crafted from beautiful Scandinavian curly birch, offering a secure and comfortable grip, and the blade steel is cryo-quenched Alleima (formerly Sandvik) 14C28N, a recycled Swedish stainless steel.
What’s in the box?:
Both knives are presented in cardboard boxes with the minimum of fuss.
The No. 14:
A good look round the No. 14’s sheath – Things to look out for here are:
A beautifully made, traditional friction/gravity leather sheath (vegetable tanned leather). Construction is from one folded piece of leather, plus the double welt insert to protect the stitching and stabilise the blade. Each end of the stitching is riveted for extra strength and the lower rivet is hollow so you can add a leg tie if you want. It also includes a good size drainage hole in the design.
A good look round the No. 14 – Things to look out for here are:
Though the handle shape and size, and the knife’s overall form are typical for this style of scandi-grind bushcraft knife, the extra ruggedness is clear from the longer blade and extra-thick blade stock.
The review sample is fitted with green linen micarta handles, nicely showing off the ergonomic shaping as contour lines in the layered micarta. Both handle rivets and the lanyard tube are brass. Somehow the blade steel looks thicker than the 4mm stock used, and really shows its robustness.
As delivered, the No. 14 has a full zero grind scandi edge.
The Lars Fält Slip Joint:
A good look round the Lars Fält Slip Joint belt pouch – Things to look out for here are:
Really this pouch is too good an option not to get. The beautifully crafted leather belt pouch (also using vegetable tanned leather), is a perfect companion to the Lars Fält Slip Joint. In this case it is a two piece construction, with the belt loop and flap being one piece which is riveted onto the stitched main pouch body. There is a welt allowing for a small drainage hole to complete it.
A good look round the Lars Fält Slip Joint – Things to look out for here are:
Casstrom’s folders (locking and non-locking) are only made with Curly Birch handles (no micarta option) which adds to their character and unique look for each knife. Liners, blade and back-spring are all stainless steel, and the remaining fittings, rivets, and lanyard tube, are brass. The sturdy blade has a large nail nick and a scandi grind; this time with a micro-bevel rather than full zero edge.
The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.
The blades are made from A8 Mod and 14C28N steel.
The Factory edge up close:
Followers of Tactical Reviews will know my views on factory edges, but to recap:
Anyone using a knife will need to sharpen it. That first factory edge is just like the first tank of fuel that a new car comes with (or first charge of the battery).
A good factory edge is a ‘nice to have’ but not a ‘make or break’ for a good knife, as you will be putting your own edge onto it soon enough.
The factory edge does however indicate the care a knife maker has put into the final finish.
It is for this reason Tactical Reviews measures factory edge sharpness and specifications, and includes this information in the detailed technical testing.
As a further look at the factory edge, this section has been added to include some high magnification photos of the factory edges.
The No. 14’s Edge:
Once you move onto the next gallery with the Lars Fält Slip Joint’s Edge, you will see the clear difference between this knife’s zero grind edge, and when there is the extra bevel.
Casstrom advise you to add a micro-bevel if you intend to subject the No 14 to heavy chopping to help stabilise the edge and prevent chipping. Having given this zero grind edge a beating to intentionally see if it would chip, so far it has remained intact.
The Lars Fält Slip Joint’s Edge:
Yes, these are magnified, and are showing a 1mm scale, but even so I feel this is more than a micro-bevel, and more into the realms of a small edge bezel. The mini-bevel shown clearly here, when checked with the laser edge bevel protractor, is found to be convexed to a final edge angle of 60 degrees (30 DPS).
What is it like to use?
For this review the fixed blade and folder have been specifically partnered as an elegant traditional pairing. The only time you will catch me out and about with only one knife is if I’ve lost all but the one I still have, so I am always partnering up knives. This is to have different knives to better suit the various cutting tasks, which is more comfortable and helps you do more work with less effort. So, although specifically partnered as a Casstrom pairing for this review, it is a partnership I would happily make for function and looks, any day.
To best show their relative sizes, this gallery includes each knife in my XL glove sized hands. You can clearly see the extended blade of the No. 14 and versatility of the smaller folder.
In my overall edged tool use, I’ve been finding where the No. 14 best fits. With the blade grind and thickness, I’ve found it struggles with outright cross-grain chopping. That thicker blade and wide wedge grind retards the penetration of each strike, ending up almost bouncing back when using a chopping action, combined with a relatively slim handle and the No. 14 wasn’t working for me as an outright chopper. Where this limitation suddenly becomes a benefit is with splitting tasks. Batoning the knife into end grain to split, and it becomes a doddle. The extra blade length giving you more room to strike it, and the wedge-shaped grind being excellent at splitting along the grain.
If the diameter of the wood being struck with a chopping action is thin enough, the wedge effect of the thicker blade is no longer a problem, so cleaning up bigger branches by whipping off the side shoots works well with the No. 14’s longer and heavier blade; this type of chopping action does work well. It is more a matter of knowing the characteristics and working with them than trying to make the knife do something it is not good at.
Despite the suggestion of adding a micro-bevel to protect the edge, I wanted to test the toughness of Casstrom’s A8 Mod and heat treat, and despite going full whack on the blade, so far I’ve seen no edge chipping; a great outcome. I prefer the zero grind edge so as far as I am concerned I’ll take that risk and stick with it.
On the subject of zero grinds, I fully intend to take the Lars Fält edge to a zero grind, but as this will take a bit of work due to the mini-bevel on the factory edge, haven’t got it done in time for this article. This will be a super fine edge, especially compared to the factory bevel at 30 DPS, so I might end up putting the micro-bevel back on.
For a slip-joint the firmness of action makes a big difference to the experience. If the action is too stiff, it can be difficult to use and worrying to close. This Lars Fält is reassuringly firm in action, almost verging on too stiff. In fact having asked people less familiar with edged tools to try it, they struggled to open and close this knife safely (I had to intervene). Due to the stiffness, the nail nick doesn’t work for me and I have to use a pinch grip on the blade, carefully taking it to the half stop and readjusting my grip to fully open the blade. In use it has certainly instilled confidence that the blade will stay where it should (with correct technique of course). Being able to chose a UK EDC Legal slip-joint with a scandi grind is a really nice addition to my carry options, and one I can carry without having to worry if I should or shouldn’t have it on me.
Casstrom give you beautiful traditional designs made with sustainable materials, that look as good as the perform.
Review Summary
