"Powder Metal steel" ? Login/Join

I've been seeing ads for knives made with "Powder Metal" steel. Is that basically MIM ?
I don't see how that could make a good knife blade, or am I misunderstanding this material ?

Thanks for those links.

I can see now that this steel is nothing like MIM.

CPM is as Crucible specific name. The PM steels are some of the strongest and best you can buy.

Yeah, in my pocket every day is a CPM S110V blade, and it’s the most impressive cutting tool I’ve owned. I understand there’s much better now, but the point is powdered metal steels can be quite high quality.

Many of the powder steels have been around for many years. 110V 15yrs, 30V 20yrs, Maxamet 21yrs, Rex 121 24yrs, 3V 24yrs... Some of these steels have been used by custom knifemakers for many years as well. Higher production makers like Spyderco, ZT.... and semi custom Chris Reeves (35V) have been using these steels for awhile.

ZDP-189 is the steel that cured me of the compulsion to keep buying new knives. It's just so good I didn't need anything else. I bet many of the other PM steels boast similar performance. That said, a lot of the knife advertisements I see now are for overpriced knives with marginal steels and flashy language, so due diligence is necessary.

"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."

MagnaCut is the new "best thing" right now. Some amazing results are being seen with the steel. It was formulated by Dr Larrin Thomas (Devin Thomas, a hugely popular Damascus maker's son). Larrin also owns www.knifesteelnerds.com

You should check it out. I have a custom being made right now with some MagnaCut.
