Toughest knife steel commonly available

The reason I say commonly available is every other thread talks about these super steels and yet , they are only available if you have deep pockets to order 10000lbs of it .....or you live on mars. I'm guilty as well because my favorites.....Unimax, S5(Carpenter 481), Caldie might as well be on Pluto . So back to reality.....senior BF members.....your right.....3V is a no brainer, but A8 is also very interesting.
 
I'm glad you cleared that up for us. Guess you might as well close the thread...

Have you done any testing or run any computer simulations showing the lateral strengths of these blade steels? There seems to be a lot of discussion lately about lateral strength in folding knives, just wondering what your thoughts are on that.
 
A8 might be in the sweet spot .....ie...... reading available, as tough as 3V, and easier to sharpen
 
Vanadis 4 extra is a 3V killer 3.5%
Mo. , but no worries....it's only available on Mars
 
FFK's responses confuse me so much...... Is he just talking to himself? :confused:

Actually Nasa published a study that deep inside Uranus there might be deposites of Vandis 4 extra.
 
The steel used in John Deer tractors is pretty rugged. While not really known as a "knife steel" it has been shown to withstand decades of use without failure. For instance, I'm sure this tractor has never needed sharpening and never will:

Here's a newer folding model if you're not into fixed tractors:

Those folders are basically broken to start with. They also are using a much lesser steel in modern years. It's pretty easy to sharpen, but the stock thickness is not sufficient to contribute to toughness. Some guys talk alloys and heat treat...that is nonsense. It's all about thickness. Obviously this is relative to profile, and basically maximizes toughness to weight ratio when explored as round bar, some guys finish it with a hex or octagonal profile...those are pretty!View attachment 458355

These babies are fixed for the ultimate in lateral strength. If only some inspired clothing-maker could find a way to make one fit in my pocket.

:D

I don't care who you are, that's funny right there! :D
