First CPM SPY27
I bought my first Spyderco cpm spy27 knife… a Yojimbo 2. I will see how it fairs as an EDC knife…having been spoiled recently by a tough bugger k390 Lil’ Temperance.
Re: First CPM SPY27
There's no doubting the science. K390 will hold an edge much much longer. But.... if you're like me and touch up your blades all the time, then it's a wash. I don't use my knives for extensive sessions of breaking down cardboard. I have utility knives for that. I don't cut miles of rope. They just get used randomly for random stuff. I have a Sharpmaker and strop on my desk, and when I grab a knife for the day it gets a couple passes on the brown or white stones or maybe just a strop. If a blade does start to dull, I probably don't notice it.
I have and carry both, so for my purposes the only difference I notice is surface rust on K390. Even with a patina. I love the knife so much it doesn't really bother me anymore.

I like SPY27. Strops back nicely and sharpens well. I don’t use my knives much daily so it’s can go for some time before needing a touch up. Plus it’s pretty stainless

Re: First CPM SPY27
I read the insert on CPM SPY27 that came in the box. Very interesting! I too like a steel that doesn’t require more than ceramic and a strop to touch it up. I will give it a good six months of carry as usual and report back.

I like SPY27 for an outdoor knife. I live in the desert, and have noticed my belt knife (a SPY27 Mule) gets sheathed in sweat, even on my belt!! SPY27 shrugs it off, looks new, edge doesn't show corrosion. I'm pretty set on the idea of stainless steels for an outdoor knife, and while SPY27 may act similarly to other formulations, it's a good neighborhood to be in.

Re: First CPM SPY27
How is it that new production knives are launching with SPY27? With Crucibles bankruptcy I would have thought that the limited supply of SPY27 would warrant sprints or exclusives.
I like SPY27, and am hopeful this may mean there’s another source?

Re: First CPM SPY27
The Balance, Dyad Jr., and Meerkat are all sprints in Spy27.
I think the supply of Spy27 is still limited, as mentioned in the Oddball blade steels thread.
Spyderco probably has a sufficient stockpile for these sprints and a run of its more popular models. Beyond that is anybody's guess.

Re: First CPM SPY27
From my limited understanding, Niagara Specialty Metals has previously ordered a bunch of steel, with SPY27 among them. They will then roll it out, and do whatever else they do (did I mention my knowledge is limited?), and provide it to knife makers. I'm guessing that Spyderco will continue to use SPY27 as long as Niagara has the inventory. But once that is gone, we may not see it again.

Didn't Spyderco together with Niagara own the steel composition and not Crucible?p_atrick wrote: ↑Fri Jun 20, 2025 10:00 amFrom my limited understanding, Niagara Specialty Metals has previously ordered a bunch of steel, with SPY27 among them.

So unless i misunderstood i see no reason why in time another foundry can make Spy 27 in the future.
Re: First CPM SPY27
I think (again, take everything I say with a grain of salt) this is more a question of economics. If the knife industry is too small to keep Crucible afloat, what does that say for SPY27? It is a proprietary steel for a maker who isn't high production (at least not when compared to We Knives and the like). I think a foundry would look at this and say the opportunity cost is such that their time would be better spent on something else. I certainly hope I am wrong, however.

Re: First CPM SPY27
I agree on short term (number of years) but at long term (10 years + ) anything can happen aslong as the owners of the composition keap working together.p_atrick wrote: ↑Fri Jun 20, 2025 10:18 amI think (again, take everything I say with a grain of salt) this is more a question of economics.

My Spy27 Yojimbo 2 arrived today.
The knife was sharp out of the box, but the blade was off-center. I feel that the assembler really cranked down on the pivot screw because it is hard to open and close. I'm not complaining, just noting the initial condition of the unit as received.
All in all, I like this version of the Yojimbo.
