New CPM Steel: Magnamax?

I for one will wait and see what is what. And then . . .

I guess it will never rust or lose an edge, but is springy enough to come back from a 90 degree bend in a vice . . .right?

I wonder if CRK would do a blade swap on my less-than-year-old Sebenza 31?

Yes, faster than a locomotive and jumps higher than the empire state building.

In reality, it will offer a new range of properties that required separate steels to achieve.

As far as bending in a vice, don't forget cross sectional thickness and length play a role in those blacksmith tricks.
 
New info from Larrin indicates it is more similar to 10V than K390 in hardness, toughness, and edge retention. So it's basically stainless 10V.

Corrosion resistance should be similar to MagnaCut when Erasteel starts production. In my opinion this is the most significant advantage MagnaMax has over S90V.

I'm happy if it's like Either of those two steels.....If it's readily available, for a good price.
This would be HUGE for the knife industry.
Really looking forward to it

They are very similar (10V and K390). I said I compared it to 10V to Crucible because that is what they would be most familiar with. Heat 1 was closer to 10V toughness-wise and Heat 2 was closer to K390. Edge retention was closer to K390. But we are splitting hairs; I put 10V, K390, and Vanadis 8 in the same “category” of products.

I worked for an electronics component manufacturer here in Simpsonville, designing equipment for their in-house use. We were using carbide cutters to trim tantalum leads, and the cutters were requiring frequent regrinding. We made the change to CPM10V, and the difference in lifespan of cutters was greatly improved.

Interesting.. I've been considering on my next steel order making the jump from CPM154 to Magnacut or S35VN as my usual steel. Of course, I would like the latest and bestest... but it comes down to what I can afford.

Certainly MagnaCut would be a massive upgrade to CPM154 in toughness, much better than S35VN. MagnaMax will be a massive upgrade in edge retention. Decisions, decisions!
 
IDK, all these new steels and I still use S35VN and CPM-3V...

I don't wanna fix what isn't broken.
If I'm happy with these steels then I'll just save the money and keep using them.

But I totally get it why someone would want to have latest and greatest. Nothing wrong with that.
 
Seven+ pages of thread here . . .I am getting g glazed-over on this . . .I just don'
t know other steels enough (or at all) to understand much of the conversation in this thread (its not you, its ME).

So, long story short . . .is Magnamax going to be a better all around steel than Magnicut?

Will it be Ike other high alloy knife steels, that are too sophisticated to heat treat for most garage-shop knife makers such as requiring programmed multi stepped heating schedules and cryogenic quenching?

I guess I will know for sure if everyone that has adopted Magnicut switches to Magnimax.

It is in different categories. MagnaCut is a really tough stainless with good edge retention, while MagnaMax aims to have a really high edge retention while being decently tough, and is also a stainless steel.

It's not better, it's different. MagnaCut is tougher while MagnaMax has more edge retention. The initial data from the first run of MagnaMax shows it occupying roughly the same place as 10V in the chart below. Both achieve the feat of replicating the performance of a cutting edge high alloy tool steel while being highly stainless.

I don't think either steel will require complicated heat treats, although they would certainly benefit from advanced techniques. Many smiths use MagnaCut and a good mix of people were given the prototype for MagnaMax with excellent reported results.
 
It's not just latest and greatest. The properties of MagnaMax offer the edge retention of K390/10V, better toughness than S90V, similar corrosion resistance as S90V. This is a steel I have been looking forward to. S90V appears to hold a slight edge (get it?) in edge retention over MagnaMax, but less toughness. 10V/K390 have been some of my favorite high edge retention steels for years, the only drawback was the corrosion.

If these steels don't fit your need/want in a knife steel, nothing wrong with that. I know plenty of folks that use 440C and love it (I still carry a Gen1 UHAK in 440C I have had for years). this new formula scratches an itch that I see as beneficial to those wanting to spend less time on the stone sharpening their knives (which over time will cause a change in the edge geometry and will affect cutting efficiency). the higher carbide steels also seem to be more aggressive cutters on meat and fibrous media (rope, etc).

Comparing MagnaCut to MagnaMax is apples to oranges....

Nice summation of the qualities of the new steel. I'm looking forward to what you make using this new steel.
 
Last super steel knife I owned was a Smith and sons axiom, great little knife, but i sold it and have been out of the super steel "game" for some time. However It will be interesting to see what people come up with on this one

In my opinion, for 90% of interested buyers in This category.....

The winner would be availability, and cost.
K390, 10v arent always easy to get.
