Rumor has it they are finally going to begin to transition to S45VN on all new blades....

As we're well aware of though, the steel is only one part of the equation. Some (many?) knifemakers don't bother to maximize the steel's potential with an optimised heat treat.

Edge retention with S30V/S35VN is all over the place when comparing different manufacturers.

That's one thing that I know CPK focuses on.

Personally, while the idea of CPK replacement blades for CRKs seems a good idea (although I have no idea how patents etc. might affect things), if CPK were to make CRK replacement blades with typical CPK quality and performance, once the word got out, they might end up spending all their time churning out blades to meet the demand. My selfish desires would prefer seeing more time on CPK's own designs ;)
 
S35VN is an under appreciated steel. People rave about M390 but I think well done S35VN is better unless you're cutting a lot of soft abrasive materials like insulation foam board and carpet a lot. But my own personal knives tend to go dull from a combination of narrow sharpening angle coupled with rough use such as small impacts and contact against hard objects while cutting wire, deburring various work pieces and scraping where edge stability/durability is more important than pure abrasion wear resistance and I have found that S35VN holds together better. They missed the target with S30V and I think that may have tainted people's perceptions with subsequent steels and someone there seems overly occupied with high alloy high carbide steel due to the wear resistance seen in different kinds of abrasion erosion tests and a poor understanding of how real knives actually go dull in use. People get excited about the wrong things and overlook some really prime options.
 
I designed this knife and spec'd S35VN. It's hollow ground, .0175" at the bevel transition

although my use for this knife is more general, it's designed with an emphasis on skinning and quartering which is why the edge bevel is so acute and why it's so thin at the transition

some of you may know that I tend to be a little rambunctious in the use of my knives and particularly those which I deem prototypes. As such, this knife saw some shit

Of particular note to me, wrt the steel I selected for it, was the knot test. You can test the flexibility, ductility and brittleness of steel somewhat with the brass rod flex test. This provides little feedback wrt how the steel responds to impact, however

what I do is find a section of tree around the diameter of my wrist, with knots, and skin it. When I get to a knot, I use as much force as it takes to get through it. The grain goes all different directions, putting stresses from all over the place on the leading edge of the blade. The hardness within a knot of also variable, and there is often abrasive deposits in there, depending on how fast growing that kind of tree is

in the case of this knife, I pushed the material past its yield point in some spots, but lost no discernible amount of material. Although it exhibited some distortion here and there, the cutting edge itself is intact

cutting other material, like firehose, shows pretty clearly how abrasion resistant the material is, although polishing the edge bevel is a good way to gauge that and has the benefit of making the knife look a little nicer without messing anything up

anyway, in my experience, S35VN is top notch cutlery steel when heat treated correctly
 
I totally get it. I’m just giving Nate a hard time. I love the S35VN that CRK uses. Keeps a good edge, easy to sharpen, if I burger it up in the field I can fix it fairly easy on the spot. I would much rather have one of Nathan’s own designs/folders anyways. A CRK reblade program would open a whole new rabbit hole not worth exploring.

Mind showing a side picture of the whole knife? It sure looks good for its intended use from what I can see.

I’ve been super crazy with the trial wrapping up on the day the court closed for COVID, now dealing with legal costs and my insane life as has become the norm.

CPK and you all aren’t far from my mind, about 9 CPKs still on display in my bedroom and on my mantle. I held the BMF last night as a matter of fact!

I was graciously given a heads up on the Osage, thank you Tony, but wasn’t able to snag it. Someone lucky did however.

I hugged my Osage EDC to comfort myself.
 
Oh, you think the gutter is your ally, but you merely adopted the gutter. I was born in it, molded by it. I didn't see the "safe for work" world until I was already a man; by then, it was nothing to me but blinding! The dick jokes betray you, because they belong to me.
