How about a PM60 Mule?

[Steeltoez83]

I was kinda bummed rext15 was chosen over rex66 bcuz the bump in cobalt I thought could bring something unique to the table. The chemistry even to the untrained eye appears a little off balance in pm60 to me. So I'd most likely pass on this one if it ever gets made.

I believe one of the main reasons why we see one steel and pass on the others is what the foundries are willing to produce. Even if there's significant inferest if the foundry says no it's end of the story. I believe that's the reason why we got Z-max instead of Rex - 86. Both are completely identical but I think Rex-86 exists only on paper.

Better toughness at higher obtainable hardness is what I've read. When I read Dr Larrins first book, the images of rex66 stood out to me. Traits of high front end sharpness might carry over to rex66 from its T15 bretheren too. After testing rex45 and rex 76 extensively I believe rex66 has potential. Just like how I believe B60 aka boron suboxide also has potential but in a different platform. Spyderco will do their due diligence, and properly research whatever avenues they wish to explore. Someone saw potential in pm60, Sal saw potential in pm60, and now it's a journey to see if the juice is worth the squeeze. We are extremely fortunate to have these interactions that we do with spyderco.

Oh definitely it's exactly what I would do if I was running the company. And well, I'm not going to try and sound like some people who are educated so I'm going to try and give you the basics that is understandable. Why did I say what I did about cobalt? Well. It really doesn't add toughness as much as you may think. Actually, a small (idk uh, let's say 3-5%) addition of chromium, known by many to be brittle, actually would increase the toughness (mainly torsionally and tensile if I remember correctly, I'm stoned sorry). Cobalt is a rather unique addition as I'm sure you have noticed that there is no "cobalt carbides" due to it's atomic radius being too small for physics. That's the size of it's atoms*. Yes it is usually added for red hardness but it doesn't necessarily need to be, other chemistry (Wolfram molybdenum and carbon) is also possible but it's slightly different. Boron, on the other hand, is mainly for hardenability but I think you know that. Can you perhaps try and explain your experiences, namely the differences, between your experience with rex 45 and 76, and what you think about 66 exactly because I won't lie I think it's a neat alloy also and wouldn't mind trying it but I would have to look at it's composition on zknives. A tip that I have - you know how it graphs everything? I think you may be at the understanding level that you should change it to moles to better compare.. what the end result difference is going to be. I don't work at Spyderco with the mule team but I do similar type work so ya man I mean we both know it's difficult. A mule.. again I think you know this I've read some of your posts you seem relatively educated (thank you ) but for anyone else, really the "intent" behind it is to figure out what works and what doesn't for say actual production and distribution. It's not cheap. At all. I guarantee you that they.. overall? Probably break even if that with this. Since it's Spyderco and 2024 instant gratification, I'd imagine those numbers may have gone black. At least to sals family and everyone that works that works there, us customers, whoever else I'm forgetting in my Oscars speech, I hope . Yeah I'm a sarcastic bastard. Sorry guys but it's just me. And sal, I don't really have time to put together all the testing results for "HIC", I asked Mike to but he doesn't know how to with a computer, would you like me to email you everything that I have or something like that send it to someone else that will put it in.. comprehending data.

Shut up kiddo. You know that I know how to do it generally speaking.

Guys, I have a theory. Hear me out here. So, we all agree with one another that.. this material doesn't exactly cut like steel. While nerd above has said that I am kinda correct, I'm not smart enough to know. But IF, zirconia.. softens with pressure, is it as simple as uhm. The edge being so thin that the physics behind the reasoning for that occuring is just. Just that? It gets softer thus cuts more like a sharp nylon 6.6/plastic/titanium/cobalt?

Hi Jason,

Thanx for the offer, but no thanx. I generally don't rely on digital predictions. They're interesting to read, like Larrin's, but the Mule Team is all about hands on "real World Experience". Also, we have some really bright folks that have been offering and sharing testing results, which we appreciate.

I can already respond for him lmao. He doesn't trust computational results either. Heck he doesn't even trust traditional scientific testing methods because he's always like well ya it.. shows x y and z but it's not really that simple with physics. When you think one thing is happening; you can be wrong! Jas would say that's how the human mind works and I can't necessarily disagree with that.

I'm literally laughing about you two and whatnot on and off when I think about this stuff. I would have lost money if I was a betting man. Oh wait; I am. Ha.

This sure looks like a conversation made for a PM.

[Steveng]

Typically I'd agree with you, and if I'm being honest I suppose I agree with sal on his.. methodology here actually. Just spent some time on it and I had no idea what exactly people wanted and I guess being a nice guy.

The only reason I disagree with you is that I can't PM sal. I know me and mike may be a bit nerdy, sorry.

Just thought I would mention it. Was not aware of the PM restrictions. Carry on...
