Only on the fire can you be beheaded for offering up good, free information.
"beheaded'??
You're one of the good guys on here, but...no insult to you...that is one of the worst supposed "steel Guides' I've yet seen. After the first 3 inaccuracies I bailed...
No - bad, inaccurate bullsh1t
Where were the inaccuracies in the link on knife steels?
Five key Terms would be a good start!
Ultra Premium Being S90V!
In fairness I do love S90V. But it is hardly a Ultra Premium steel. Actually all those listed are decent steels when properly used. But not Ultra Premium.
The graphs they use are of common factory HRC, not what is being reached by those that know how to heat treat! Which means the edge retention and wear resistance graphs are not accurate either!
The fact that they are missing a bunch of very good steels in the list would be another!
There is a lot of good information out there, this not being one of them. But to each their own.
