Shirogami 1 , SKD 12, Cobalt Special, Maybe R2?

What are your thoughts?

What should the next Sprint run steel be?
 
good question...I know little of Japanese super steels, but from a short googling, I found this steel designation : Cowry-Y supposed to be one of the latest Nippon super steels.
 
Nice, yeah the cowry steels are very exclusive and expensive.

I believe there only used by Hattori knives.

Ooo

Maybe something like YXR-7 tool steel like whats on the Rockstead knives.
 
From the Zknives all, thanks Gator

This is my favorite steel to sharpen

White #1 takes a killer edge



Cobalt Special

Basically Super VG 10, everything you love about vg10 with the volume turnt up :P

My current favorite stainless


A Japanese version A2?!

This is one of the easiest steels to sharpen, the burr seems to fall off on its own


Rockstead has some impressive videos displaying the toughness at very high hardness with this steel. Sharp stuff too.


SG2 fell through, maybe R2 is the answer!
It's like S30v that takes a better edge at higher hardness.
 
If it is clad then I don't care. Did not buy the HAP 40 because it was clad and I actually started the thread at Spyderco forums asking Sal for a follow up to Super Blue. Please make it solid slab!!

Why? The cladding has huge advantages, the best is that the pivot area on the blade won't rust away.

I have the endure in SB and Hap40 and the SB delica. I think they're great, but there is a concerning issues about cladded steels. the issue it brings up is that steels have different heat treat protocols, so how would they go about optimizing this when their have two very different layers of steels welded together? perhaps it is not really an issue?

Not an issue. The heat treatment protocols are for the core steel.

The outer cladding is low carbon stainless and remains soft even when heat treated the same.

This makes a stronger blade

I can't speak for TBD, but when the superblue knives first came out, I found myself wanting the calys more than the frn knives because they were solid SB. I'm a little embarrassed to admit this, but deep down I think my reason was that the solid carbon steel would look cool with a nice patina. I have owned both styles now and what I've found with both superblue and hap40 is that I absolutely love carrying and using these steels in my everyday folders. Because they see so much use, I have really come to appreciate the laminated blades and the advantages they offer. Solid for show, laminated for go. That's pretty much the way I see it.

Edit: Having said all that, if they were to offer a model with a solid hap40 blade I would snatch one up in a heartbeat. Point is I'm glad they've offered both styles and I hope they continue to do so.
 
If it's being used in a model I'd buy, then VG-10. Tool and carbon steels are a total turn off for me.

Yea, it is nice to get a big chunk o' steel. I too was drooling over the SB caly's

But the reality is that I wouldn't be able to keep up with the maintance. Especially with other knives in my rotation.

Evently the novelty wears off and the knife become alot of work to keep rust out of the pivot area.

Having stainless in that area is a huge advantage.

The cladding material is selected to optimize heat treat and bonding of the two materials.

Daido makes a steel called MRS-30. 1.15 carbon ingot steel. Al Mar used the steel in his introductory models. He called it RS-30. There are many interesting steels made in Japan.

I'm currently using a Hitachi White kitchen knife made by Murray Carter. Very thin, gets very sharp. Murray clads his to reduce corrosion , but he's forging them.

Cladding also has manufacturing advantages in cutting and corrosion resistance.

Ah, kind thanks for the info. I hope these sprints will be recurring with other exotic steels. they are an affordable way to experiments with these high end expensive Japanese cutlery steels. Oh and the specials FRN color are a pleasant option too! *in Royal Blue would be awesome* :)

Whoa cool, thanks Sal

MRS-30


Never heard of it

Had to look it up on Zknives :)





It seems to be a suped up version of AUS 8

I bet it takes a great egde.

Probably performs best at 60hrc?

Loving that Carter cultery huh?

Woo great stuff, Carter makes an amazing blade.

I hope that brings us one step closer to a Shirogami Sprint ;)
 
Yes, I would like to see super blue, laminated BUT THIN !
I am tired of seeing laminated knives that are all thick. That is pointless, except maybe the rust thing. For me a laminated blade allows the opportunity to have a blade that is really pushing the hardness but has flexibility and strength.

At least a three inch blade 2mm thick or even 1.5mm.

Handle some combination on the order of the bidirectional texturing and the Ti fluted. Maybe go all the way and have a rising sun where the clip hits the handle like the FRN oval but round (like on the Manix I guess).

Not a bush craft knife for certain.

Not a knife for everybody but for the person they are looking for in the movie Circle Of Iron when Roddy McDowall says "We are looking for a person who can bind an elephant with a spider's web. Not stun him with a kick".
