Spyderco 4v is 65hrc

#1

Post by Pelagic »

Just saw a video with official Rockwell results of the burgundy pm3 4v exclusive. 64.9hrc!

More 4v would be nice.

Interesting; Spyderco (or distributor requests) seem to be pushing their higher end steels in sprint runs to higher hardness as of the past 6ish months. Would be more interested if they didn't feel the need to coat all their exclusives (St. Nick's). Cheers for the info Pelagic!

Would the DLC effect the hardness test? Is it safe to assume they would shoot for the same hardness range for different models?

No and Yes.

No wonder I broke the tip on my Manix 2.

Good to know, Pelagic, thanks.

Yes.

And on the subject of DLC, from what I understand it can POTENTIALLY make a small difference, but not usually. And when it does effect results, it typically reduces the HRC number (making the steel appear slightly softer). I'm no expert though.

Nearly 65 HRC... is that actually desirable?

That's just one test preformed at one point on one blade that is DLC coated. One tenth of a point isn't worth the word "nearly" to me. It was 65hrc. BBB has shown us time and time again how 4v at 65hrc performs, it's plenty tough for almost any task while having extreme stability, strength, and edge retention.

Would it be safe to assume the 4v Mule was near or at the same hardness?

There are few people that appreciate Spyderco's use of the Supersteels any more than I do. I don't even mind the extra effort that it takes to sharpen many of these newer blade steels. But I'm beginning to wonder if having them heat treated to a hardness so high up the charts to where you can only sharpen them with diamond is indeed advantageous. Now please hear me out because I'm not trying to kill anyone's joy or to take a "stick in the mud" position on this interesting discussion. But really the 2 knives I've used lately with a Rockwell of about 61 to 62 I really couldn't find much advantage over some of my frequently used Spyderco models with VG-10 or even D-2 for that matter.

I'm wondering if a Rockwell hardness of 64 might just make it so brittle that it may not be a good trade off in the long run. But hey if my thinking is not on track let me know why I"m wrong. But the curious side of me would like to see how 4V in a good fixed blade knife would perform and hold up with outdoor cutting chores. Or does this 4V have other properties that compensate for the trade offs you get in many cases?

I guess what I'm getting at is>> can you just get the steel so hard to where it borderlines on the ridiculous??? Or do I need an "attitude adjustment" :D

maybe I'll get a province and hit the woods. Only one way to find out. Whenever they're available that is.
