The Mystery of Hultafors Knife Steel Solved

Flint knives

After my review of the Hultafors GK Heavy Duty knife, I kept trying to find out something more about the carbon steel it is made out of. This, then, unknown high carbon steel continued to amaze me and I simply couldn’t let it go.

The answer to my question was closer than I thought – Facebook. More precisely, Hultafors Group Facebook page. I asked them my question and got the answer within several days. What did they tell me? Well, watch the video 🙂

I also took the opportunity to talk a bit about the importance of steel type, its chemical composition and heat treat (quenching, hardening, annealing, tempering and all that good stuff). For that reason, I brought out some of my other knives for comparison: Condor Windfang (1075), Blue Mountain Forge bushcraft knife (o1 tool steel) and a hand-made, Scandinavian knife with an antler handle and NC6 high carbon steel blade.

Things you should know about batoning

To baton, or not to baton: that is the question. Why or why not? Is it really such a bad idea? How old is batoning and is it stupid?

It all depends on context I suppose. I have batoned since I knew how to use a knife and never broken a single blade while doing it. After watching several videos featuring knife fails, I think most of them have to do with either a bad heat treat or bad batoning technique. If you try and pound you mora classic through a 3″ knotty piece of seasoned oak, you’re asking for it. Same thing if you whack your knife at an awkward angle.

But if you know what you’re doing, if you’re being sensible, you can get away with unbelievable things. Like my grandmother did when she batoned a thin, stainless kitchen knife through bones pounding on it with a hammer for decades. I still have and use this knife BTW 🙂

There is one thing I don’t mention in the video. It is to do with heat treat and blade hardness. I’m no expert, but from what I understand, different knife types are made with different purpose in mind, which is reflected in steel type, and hardness. Some knives are meant to be rather softer (bainite or spring temper) and less brittle. These will be much better for batoning or prying. Other blades, such as the super hard Roselli knives from the UHC (Ultra High Carbon) line – HRC 64 to 66! and carbon content 1.5 – 2.0% – are obviously designed for different tasks, as their hardness approaches or even exceeds that of metal files. They will perform best when used for skinning and dressing game and should hold an edge much longer than softer, less brittle knives.
