After thought to my homecoming from Finland hike - Casström Lars Fält Knife - K720 vs Sleipner steel

Yeah home again, getting everything tided up for the next trip or just everything back in to order in generally with my kit, which worked out very well and I'm not going to alter anything, may just trough some unused stuff out.
But well the main thing is that I wanted to tell you a bit more of my afterthoughts, specially regarding the Casström Lars Fält knife, since I found out or rather remembered some technical details I forgot to mention on the trip.
It's because there are two sorts of steel available for the Lars Fält knife that serving different needs for Bushcraft, the blade marked up with “K720 steel” containing a higher grade of carbon steel, so this is better for thronging sparks working with a magnesium rod much better, while the 2nd does tend to rust lesser or not as easy, containing more chrome and makes the steel slightly harder for heavy work.
So make your mind up what you gonna be use your knife for, if you want to get yourself one of the very useable and bushcraft dedicated Casström Lars Fält knife's, this info should make you aware of the differences to look out for of the two types of steel this knife is available from dealers or shops, because they tend not to know nor care about the properties these two blades can give you for different needs.

Stated on the Casström web-page:
About K720 steel:
Böhler Tool Steel K720 is a very tough and strong oil hardened high carbon tool steel. The chemical composition allows it to be hardened to a high degree whilst maintaining ductility and toughness at the same time, as it is easy to sharpen and can obtain a razor sharp edge. Whilst easy to sharpen, the low chromium content means it will tarnish if left wet, and it must therefore be wiped after use and protected by oil or wax when put away for storage.
Composition: C. 0.9%, Si. 0.25%, Mn. 2.0%, Cr. 0.35% V. 0.1% (HRC 58-60)
About Sleipner steel:
Sleipner steel allows the knife to keep a sharp edge very well, for longer and also during very hard use without chipping to the extent that is often seen in stainless and high-alloy steels. The chemical composition allows high temperature tempering to a high hardness with retained ductility (ability to deform without breakage) and toughness, while still being relatively easy to sharpen and capable of obtaining a very sharp and durable edge. Due to the 8% chromium content, it will resist corrosion to some degree compared to regular carbon steel (around 0.5% Cr) but not as well as stainless steel (13% Cr). Therefore, the blade should be dried after use and protected with oil or wax when stored in a high humidity environment.
Sleipner steel belongs to the 8% Cr die steel category and was developed to have toughness close to simple tool steels like O2 and A2 but with much higher wear resistance, closer to D2.
Composition: C 0.9% Si 0.9% Mn 0.5% Cr 7.8% Mo 2.5% V 0.5% (~HRC 60)

Update to the latest Lars Fält knife release:
Just seen that Casström brought out a newest edition of the Lars Fält knife (seams to be the Sleipner steel) including a Magnesium rod attached to the sheath, with a Birch handle to match the knife handle too.

When I work aboard shjp, I use carbon blade for serious cutting. When I chase trolls through woods, I use those pretty butter knife chrome blades.

[@Mogge1981]

For a ferro rod it doesn't matter what steel the blade is made of as long as it has a 90 degree spine. When it comes to striking a flint against it to create a spark it has to be a carbon based steel.

[@Airik1111bibles]

Left and right just means what sheath you get with the knife ...The handle shape doesnt change its just a left handed sheath carry option is available. 99% of companies dont offer left hand sheath options.

[@spookycrow1]

Yes, I recognized that after I uploaded the video ;-) You are right the knife is no different at the handle, only the leather sheath ;-)

[@Dr.Gunsmith]

You should try the joker bushlord it’s not a bad knife for the price.

[@spookycrow1]

Yes, I had a look at the Spanish made Joker knife, and it really looks nice, but since I have the Caström Lars Fält knife already in use for years now, it serving me very well for my needs. I'm more than happy with it, so there is no point getting any more knifes at all, I'm not a collector but required a good reliable tool. ;-) Nevertheless, the Joker Buslord definitely would make a good alternative too, has a slightly thinner spine (3.6mm) than the Lars Fält (4.0mm), but would do for most tasks.

Awesome knowledge share

[@spookycrow1]

Thanks for liking, was a quick research and all came together.

[@jhtsurvival]

I have a joker nordico in k720 i love it.. subbed

[@spookycrow1]

that nordico blade looks nice and got a symmetric shape, seams to be a good all-rounder too without fuss.

[@JonathanRobinson11]

Threatening some sausages!😂

Hej! can i use the oil for my handmade Axe as well? i got one from "hultafors" handmade blade. Thx for this quick video and explanation.

[@spookycrow1]

Yes you can! Ballistol will keep your axe rust free and always in good shape.

[@greekveteran2715]

Ballistol and wax for long term storage (for exain all of themmple when Spring comes, the storage might last until the next winter) or if you're going to use it occasionally, use just Ballistol. The Material on the Spray cans they sell, isn't the same in all of them, read carefully before you buy. Also, if you want to use Ballistol, on a knife or leather, wood etc, I'd advise to get the Ballistol in the small glass bottle, because it's the original product, without the added chemical stuff they put inside the Spray cans. Hope this helps.

[@spookycrow1]

@@greekveteran2715 Yes, you are right with your additional infos regarding the spray cans version of Ballistol. My father used to use the airosol-Ballistol only on his hunting shotgun rifle for convenience to apply a thin overall coating, but the liquid Ballistol in this glass bottles is the original and recommended on steel blades, leather and wood for general maintenances and long-term storage, you are absolutely correct there, thanks for your comment.👍

[@matsalm2943]

Why not get a good scraper for you firewood? Even if I have a firewood for emergency on my knife and the spine is sharp I will use my large firewood and a good scraper. I have that always in my bakpack together with dry birch back for starting fires. What you get as fumes and sparks on the blade from the firewood is presumably not very healthy if you cut food afterwards.

[@spookycrow1]

Well, I don't carry a specific tool for every single task to reduce the amount of items to carry, and more important not to lose one or the other while keeping track of what I got in my pack, because the more someone carry's the clutters the pack getting too. I just one of the “less is more” minimalistic multi usable kit approach and keep things as simple as possible. Update to the Lars Fält knife: Just seen that Casström brought out a newest edition of the Lars Fält knife (seams to be the Sleipner steel) including a Magnesium rod attached to the sheath, with a Birch handle to match the knife handle too.
