First Impression of You get from Fallkniven S1X Fixed blade Knife
Thanks to Hollywood for creating an imagination that we all have with Survival Knife? If we ever imagine a survival knife, an 8-10 inches long Bowie with serrated edges, oversize jimping Micarta handle and so on comes to our mind. And in action you see a knife breaking apart a wooden table in halves and we all know that it’s not humanly possible.
Well, as we all know Fallkniven knivesis best known for its survival knives, and they are expert in manufacturing best of the best survival knives in the world for hardcore outdoor men and women alike. The knives are more purposely built and you find them calm and cool in their appearance so goes for Fallkniven S1X knife.
Fallkniven S1x Knife Blade Material
Fallkniven S1X knife’s blade is built from Lam.CoS steel, crafted so well, that it gives the sharpness as good as surgical scalpels and with 420j2 steel, a toughness it needs for survival. A perfect blend of hard and sharpness material to last long and no chipping on blades too..!
Lam. Cos Steel means?
Many of you are unaware of this term, and doubting what is it? Lam.CoS Steel is actually a type of steel a mixture of cobalt and 420J2 steel, normally used in surgical implements because of very high sharpness & hardness properties. Thus, the material used in Fallkniven S1x has overall rating of HRC 60 which is great.
One more thing, I want to mention is that laminate Lam.CoS Steel is 20% much stronger than normal steel types available in the market. Because Fallkniven S1x is a survival knife, and one can use to under tough and hard times, so the sharpness of the blade and toughness of steel matters the most.
Keeping the survival factor in mind, and universal situations for all terrains and climates it’s been designed and Lam.CoS Steel turns out to be the best option for Fallkniven Company.
Fallkniven S1X blade shape & Sharpness
It’s a drop point blade, with blade thickness of 0.24” inches. The width of the blade is Okie, It’s not very wide nor short for most batoning tasks i.e. 1.25”. Overall, blade length is 5”1/4 quarters or 5.125” making it normal sized survival knife.
You must know that every survival knife shall not mean a long bowie knife or a machete, Survival knives are general purpose all terrain knives, a tool you can use to do most of the tasks, that’s why Drop Point blade are always seen on survival knives because of their belly.
Fallkniven S1x blade has been given CONVEX grind instead of flat belt grind typically given to most survival knives but they are made with HC420 steel most of the time, where their sharpness gets dull quite often and they are easier to sharpen.
Furthermore, convex grind stays longer, is difficult to have the convex sharp edge as it consumes more time, but spending a fortune on such any survival knife then one must have premium and as you know, Convex edges or grinds are always premium
But, Sandi grind abbreviation Scandinavian grind popular for mostly hunting, bush craft and outdoor knives. Therefore once in wild, we use wood and I’m happy with the grind, because once you use it, then you know the material of blade and the grind given are optimal.
I make wood shavings and with Ferro rod, lighting a fire is no issue.
Well, convex grind as mentioned earlier is hard to sharpen and for that, you require high grade wet silicon carbide and diamond coated dry stand paper with semi hard surface which can create by putting some soft foam underneath. But, you cannot sharpen you knife when in the field unless you have all the equipment. Also note that DLC coating has nothing to do with sharpness of the blade, it’s more protective for the entire blade. It just took me 10 mins to razor sharp it after batoning.
One more thing, if you are looking for razor sharp survival knife, then do not good for Fallkniven S1X. Because, straight from factory brand new is not razor sharp and doesn’t cut paper like butter as well. Reason: its survival knife made for more rugged jobs not for EDC jobs of pocket knives where you need extreme sharpness and all. Given, it’s my experience and I felt like sharing here under sharpness section of this knife so I’m mentioning it.
Fallkniven S1X Handle
The handle is 4 inches plus, for all types of hands and even wearing gloves, they are great. Secondly being a full tang knife and having lanyard hole is handy. As per the shape of the knife handle it fits comfortably in the hand and it’s a perfectly balanced knife.
But, one thing you will notice that the knife scales are thinner on this knife as compared to most of the survival or military knives. As its 6mm thick full tang knife between its handle scales, more thickening of scales leads to rather imperfect grip.
If you are paying premium doesn’t mean you should get extra of everything, few things are more utility based and same goes to the handle scales. As many people think that the scales are thinner but wait they are THERMORUN scales. They are plastic but soft gives rubber feeling making a more comfortable grip while cutting or even batoning your hands do not feel the pressure as they should. It’s my own experience and definitely it is subjective.
Best part is these scales are removable from your S1x knife, you can change them with scales of your choice or if you do not like the scales design, and want bone, wood or Micarta handle scales, you can easily replace them. As Fallkniven knives have been using them for past 30 years and as per feedback they received from their users, they think that it’s the best option for all types survival knife.
Benefits of S1x Knife
Fallkniven S1x Knife has been designed and developed while keeping in mind of its users. As, it’s been used by Swedish Airforce and definitely in air force you have pilots who have them therefore, its sleek yet performing. Similarly US Marines and Navy has them too and for their basic to most advanced survival and with a knife of total size of 9.75 inches with best HRC steel ratings
S1x and S1XB both are light in weight which are just 290 grams almost equal to Apple IPhone 11 Pro Max meaning you are holding a smart phone in your hand lolz. With such low in weight they still are an ultimate solution to all survival needs. You need knife for cutting meat, slicing or making wood chips for fire. You are not there cutting or chopping of trees.
Actually, when you are in field or in wild or under survival situations, you look for already dry wood. You do not chop of branches etc. All you have to do is hunt and eat and this is the best knife made for that purpose. Then comes the thermorun handle scales, majority consider it just as another polymer or rubber type scale handles but the fact is its highly insensitive means get affected by majority of the corrosive elements and even DEET, which is a corrosive element present in Mosquito repellents and which even dissolves plastics. 0.24” neck and hard yet point tip of this knife can cut and puncture anything you can imagine possible with human hands and power.
Similarly, comparing its sharpness against pocket knives is foolish which I have seen many you tubers doing it. Its survival knife, edge and sharpens retention is the key here once you are in the field, razor like sharpness fades away as soon as your knife hits anything hard.
Sheath of FäIlkniven S1
Yes, I deliberately haven’t discussed it so far. FäIlkniven S1x’s sheath is mate from Zytel (fiberglass reinforced nylon material) and again it’s tough, impact resistant material and can be easily worn on belt. Secondly, it’s quit slim, tidy and discreet.
Locking system at the top makes virtually impossible to dislodge accidentally which I like the best.
If you lose or suppose if even the belt strap attached with nylon and Zytel sheath is no long there, you can still you the side holes of the sheath and tie your belt, similarly for backpacks, it can be easily adjusted the way you want, and the locking mechanism makes dislodging of the knife virtually impossible.
I won’t be writing much about the sheath here as its worth experiencing it and do not want to ruin your experience but do share in your comments below after reading my review.
Concluding Fallkniven S1 Review
Well, the edge and blade shape retained, given a full beating by myself, from soft wood to hard wood. Made a carving in wood just to check out the knife handling and precision and all went good.
While it was hitting it hard in dry wood and I saw the wood and DLC coating being damaged, I though, all is ruined during the test but once I gave it a thorough wash DLC coating having HRC of 83, remained enacted as wood resins got washed away and the blade was new as before.
Now comes the prices, at Amazon I have seen it being retailed at 256$ whereas, Dlttrading, Blade Hq and other websites are selling it at around 230-240$ + free shipping.
But, you can buy them at much cheaper price on the links given above. I love to help local business yet helping my friends getting best deals on internet. You will find the lowest prices on above mentioned links for sure.
