Re: CPM SPY27 steel

You hear the term "sharpener's steel" tossed around, some folks in that camp also want stainless. SPY27 is the new "Stainless sharpener's steel". Props to Spyderco for making it happen. Anyone know which foundry it's out of? All CPM (Crucible Particle Metallurgy) are made by Crucible Steels USA Yes...

Re: CPM SPY27 steel

Not to be a debbie downer, but it seems so similar to a few other steels we've had available for some time now, I can't really hop on the hype train :confused: Finer Carbides at lower volume with higher obtainable hardness with simliar wear to SG2 More edge stability, thinner edges, easier to get a...

Re: CPM SPY27 steel

Doesn't look anything like PSF27. The Carbon, chromium, Vanadium, Niobium and Cobalt confirm that. What it does look like is SG2/S35VN but we have a lot of Niobium in there. Looks like a good sharpening steel and like they are chasing a steel that takes a better edge than the S30v stuff we are used ...

I'd be curious if some kind of scratch test could be done with an object if similar hardness.

Re: Sal, can we please get a Para 3 lightweight in grey/maxamet please?

I too find myself carrying the Para 3 lw more often than any other knife I own, especially since I work in an office. I'll be first in line for a grey/Maxamet. It will more than likely happen seeing as how it's such a popular model. If not, I'd be shocked. :eek: Not trying to bash you...but if you ...

Re: Disappointed with M4 Mule Performance

Well, you have to rule out the sharpening, if you're just burnishing the edge to death on ceramic and never making a crisp new apex by cutting steel to establish a fresh new apex than it won't work as good as it could.

Re: Best Edge Performance Steel between these choices?

Hey Shawn. This should be an interesting thread. OK. For me I'll take CPM Cruwear then K390, Rex 45 with Maxamet last. Pure abrasive resistance isn't my most desired attribute but I do rate it on my scale of personal needs above corrosion resistance which is last. Cruwear may have the lowest ceilin...

I made a Carbide Hardness Chart for quick reference, useful for folks that are curious about which steels would be more wear resistant than others and what stones to use.

Non Afi Dream knife.

The biggest secret to rust removal. Bar keeper friend. $3 for a lifetime supply Should the worst happen like leaving my knife outside in the rain for a few weeks than I'd just sprinkle this stuff on and light scrub it off with a sponge, no steel wool nonsense.

Re: K390 & Corrosion

Corrison seems to be a real bogey man here. There just isn't a way to get the same performance as K390 in a stainless steel with what is currently available in steel chemistries currently produced in 2020. Everything has a trade off, I'd hate to see folks scared off from enjoying something very spec...
