I didn't realize that by the time I'd plunked out all those letters, you already had a conversation going, Mike.
I was pretty young when I realized that some people virtually demand one sided conversation, and the best thing to do is visit with the other voices in your head, as they are always much more amenable. Many school teachers seemed equipped with this feature, so I became accustomed to just keeping an eye on them.
I can tell you for sure that Chris Reeve is very widely recognized as the father of S30V, and every company that used S30V (which is virtually all of them) touted it as the first steel developed specifically for knife blades. As far as I know, that was the beginning of powdered steel, and all sorts of powdered knife steels followed.
S30V was supposed to work at HRC 61, but they had to temper it back a couple points, which totally changed it's performance. It took Crucible another 10 years or so to come up with S35VN, which met exactly the performance they were trying to achieve with S30V, which seems to indicate they still have knives in mind.
I also know first hand that Crucible worked with Gayle Bradley when they were developing M4. Gayle was using it to win the big cutting competitions that were so popular at the time.
It surprises me to hear that any steel is used for dies in the injection molding industry. Cooling, or heat transfer of the dies is critical, which is why all the ones I know about are aluminum. I would think that machinability would be another optimal quality, but the powder steels I know of are exactly opposite.
Don't worry Mr. Me2, I'm used to your unusual opinions, which is definitely Not to say I don't respect your unusual opinions. I certainly don't profess to know about powder steel that isn't used for knives, and I do know that knife steel hardly registers at all in the steel industry.
It's just surprising to know how many powder steels happen to make up such a high percentage of high performance knife steels these days, and I really don't know about other uses. I know powder steel is very highly alloyed with strong carbide elements, and awfully expensive to manufacture and pretty involved to heat treat, but like I said, I'm pretty limited to blade steel.
