Wow! They went HAM on that REX45 sprint! So cool!

And 20CV small compression lock? I definitely want the Watu! Watu bout you guys?

Thanks for finding this!

So it looks like Larrin expects it to have less edge-holding than the current standards, like S30V. That would have been my guess
, just looking at the ingredients. My question becomes: why? I think Spyderco already runs their S30V a bit soft. Has chipping on it (or S35VN/S45VN) been such an issue that they need to go with something tougher?

I'm guessing it's a cost savings measure. Less volume of the pricey elements in the alloy, and more importantly, probably easier to machine - so few labor hours and consumable belts used to make a blade.

We'll wait and see, I guess.

He's purely theorycrafting based on the alloy composition at this point. We're not really sure what Spyderco is doing with the steel.

Source? Spyderco is #1 for heat treat from what I've seen.

Edge testing results such as Cedric and Ada. Yes there's more to edge testing than heat treat, but the fact that lesser steels (based on recipe) regularly underperform Spyderco S30V suggests they could get more out of it.

Note that heat treat is a trade off between hardness vs toughness. It's likely that Spyderco is intentionally running S30V at the lower end of it's potential hardness spectrum to maximize toughness. Customers would complain much more about knives chipping than about them gradually getting dull.

Note also that similar edge testing shows that Spyderco's sprint runs tend to get the steels closer to their maximum potential, compared to for example what a custom knifemaker could achieve. My guess is that they know enthusiasts will buy the sprint runs, and run those harder relative to potential then they do regular models.

Here is a source for some hardness tests -

Looks like they run S30V around 60 on average. If that's lower than competitors, then site a source.
Saying they runs sprints at higher RC is pure speculation. I'm skeptical.
S30V Amalgam - 60.7 HRC
S30V Para 3 - 60.3 HRC
S30V Manix 2 - 60.1 HRC
S30V Manix 2 (Backlock) - 60 HRC
S30V Military - 60 HRC
S30V Paramilitary 2 - (58.8 - 59) HRC
S30V Delica Wharncliffe - 59 HRC
S30V Delica - 59 HRC
