I agree 100%Vivi wrote: ↑Thu Mar 14, 2019 7:14 pmK390 and CTS204P both impress me with their combination of edge holding and ease of sharpening. I feel like both are easier to sharpen and quicker to reprofile than S90V, S110V and Maxamet (Though I've only tried those steels briefly, one knife each). I hope to see Spyderco using more of each.Deadboxhero wrote: ↑Thu Mar 14, 2019 5:25 pmAgreed, highest wear resistance and edge stability in a Spyder currently.
Really a better comparison is the Rex 45 vs K390.
I still put K390 a tier above Rex45.
Just has more aggression.
Top dawg for me is still definitely Maxamet but K390 seems more friendly in the sharpening and durability department.

My sweat makes it get small orange rust spots, but nothing else has caused it to rust for me. That's pretty normal for any blade steel for me, even stainless.
If corrosion resistance isn't a big concern, I haven't seen a better steel for folding knives than K390. I'm generally a fan of simple steels that are quick to sharpen, and don't place muchvvalue on edge retention....but K390 is very impressive stuff.
I've never seen a steel cut so much cardboard and still have a shaving sharp edge. I touch my knives up when they stop scraping arm hair, so I don't care about how long a steel holds a working edge. Most high edge retention steels seem to lose shaving sharpness pretty quick, but not K390. I'm glad I gave it a shot.
Love both of them too.
