This video is interesting from a smithing perspective, but also very informative as it pertains to the various types of steel used to make knives.
It should make selecting your next knife simple and easy – depending on what properties you want your knife to possess.
In a survival situation, a dependable knife is imperative. Without one, your job of surviving is made incredibly harder.
Understanding the type of steel used in making a knife, however, is equally critical – like all tools, different knives perform different tasks and matching the type of steel to the task will make your job much easier.

I use the big concrete saw blades that they throw away when the diamonds are gone for cutting concrete blocks, you can get 3 good blades perfect for skinning knives the steel is quite hard.
I toss mine in slabs and pour over them or just toss them in the dumpster. I never thought of using them again. Although when the diamonds wear off I’m pissed at that point cause I have to chase down another blade lol.
True, I go around and ask em to save them for me a few make it into the roll off so I dumpster dive too

Old files/rasps and saw blades work well. Chevy and Nissan leaf springs I know for sure are 5160 carbon steel and make a gorgeous blade or ax.
