CPM SPY27 | Edge Performance

I'm eager to see the results

100% I saw Submicron’s review on blade forms I am hoping Shawn can confirm or deny these test. Based on sub microns review on waveform this might be the most undervalued and under rated steel to come out in a long time

I went to check out these results, and am flabbergasted.

I'm very surprised that other people have not published tests. We really need that. What if mine was inadvertently run harder (which I'd love) than the average SPY-27?

Also it should be noted that my tests lack a broad data set of different steels. I have more testing to do, but it is time consuming.

I managed to get some runs done on a S90V Delica. I need to do one or two more runs because I'm still too close to the factory edge. I can say my Delica S90V beats my Para3 SPY-27 in the cardboard test. For cardboard tests, in my mind at least for now, SPY-27 is stacking between M390 and S90V.

But that's all on new and clean cardboard which is not abrasive and not hard. With something with those properties, like any steel, SPY-27 will not stack the same.

Would you say spy-27 sits exactly between them or that it leans more down toward m390 or up towards s90v??

Using a 600 grit edge with everything sharpened and stropped the same, my tests so far have produced a result for SPY-27 that lands between M390 and S90V.

To me that seems high considering CATRA results and how SPY-27 was marketed as being comparable to S30V.

Again my tests were through clean cardboard, which is non-abrasive. Through a more abrasive material, my expectation is that SPY-27 will perform and stack as CATRA predicts

Since many people have a usage profile that mostly involves cutting non abrasive materials, I feel that simple cardboard tests do matter. We need more of them.

I'd like to see Outpost76 get ahold of SPY-27 and do his cardboard test.

Thanks Submicron, your work brings color and context to the knife guy dream.

Any updates on the tests?

I'm still waiting for something to come out in SE.

[JRinFL]

Non-scientific data point: My Para3 in Spy27 factory edge seems to have performed a bit better than my S30V factory edge knives in card board. Caveats are that the knives are not identical and neither is the cardboard cut. I think it will be a good all-rounder steel as it was designed to be.

Burned some DLT points and got me a SPY27 native on the way to play with

Late to the party, but wanted to thank Submicron for his cardboard tests of SPY27. If you haven't seen, it's a good read:

Agree that CATRA, while very informative, doesn't match a lot of real-world usage. So I think the cardboard tests give another important insight into steel performance.

I couldn't agree more. With Spyderco's line up with so many important models in SE I truly think there should be isolated tests just for SE alone. I kind of suspect that this newer blade steel will be decent in SE but some testing would be reassuring.

I'm also hoping that the upcoming C-60 Ayoob Sprint run will have SPY-27 in both edge types.

Not really related to SPY27, but I thought the speculation about Crucible ceasing production of S30V and/or S35VN to be interesting.

After reading Larrin's and BBB's stats for the knife, I've attempted to "box" the area where SPY27 lives on Larrin's toughness x hardness graphic. I've seen hardness listed from Rc 61 to 62, and toughness from (avg) 8 to 11 ft lbs. From this perspective, it looks to be M390-ish, S35VN-ish.

Wouldn't surprise me if the steel performed better on less abrasive cutting, given its carbide volume isn't huge.

[Bolster]

Silly me. Larrin himself put a dot on a newer chart to represent SPY27. The yellow "box" was added by me. Larrin's Rc test was around 61 and BBB's was 62. I think the 62 was as-delivered from Spyderco, and the 61 was Larrin's own treat, is that correct?

62rc is what was measured on the para 3 LW

The Catra testing Blade is 61.8 rc which will be a great representation of what Spyderco runs it at.

Cool test. I guess the rubbish S30V is still not that rubbish as some people claim :D
I want to ask, what handle was more comfortable in use, G10 or FRN?

There is no denying the G10 felt sexier but I didn't notice any hotspots between them.

I like the LW for carry better because it disappears in my pocket It doesn't tear up my jeans like the G10 peel ply does.

I’ve always been curious about the BESS testing scores. It just seems, to my inexperienced self, like the results could vary widely even at the same sharpness.
How exactly do you test the knives with it to ensure somewhat reliable results?
