MagnaCut, M390, and S35VN: Every Premium Steel EDC Knife Ranked

The knife steel conversation fills entire corners of the internet with arguments that mostly don't matter for everyday carry. Here's what does matter: some steels hold an edge longer, resist rust better, and tolerate resharpening more forgivingly than others. The premium steels are real. The price premium they command is usually justified.

We filtered the CarryIndex database for every production folder running the genuinely high-tier steels: CPM-MagnaCut (the new benchmark for corrosion resistance + toughness), M390/CPM-20CV (Böhler and Crucible's twins — high hardness, excellent edge retention), ELMAX (fine carbide structure, exceptionally uniform), and CPM-S35VN (the previous gold standard, still excellent). S30V is not on this list — it's a competent steel that doesn't belong in a premium ranking.

Ranked by price ascending. Value doesn't always mean cheap.

BanterBest S35VN Value

WE Knife Co

CPM-S35VN61g$75Liner

CPM-S35VN — upgraded from S30V in meaningful ways: better toughness, equivalent edge retention, improved machinability. WE Knife's ball-bearing pivot makes this the smoothest sub-$100 folder made.

DekaBest MagnaCut

Hogue

CPM-MagnaCut79g$170Button lock

CPM-MagnaCut is the most significant steel introduction in a decade. It combines corrosion resistance comparable to H1 with edge retention that surpasses S35VN. In the Deka's button-lock chassis at 79g, it's the ultralight premium carry.

Bugout 535Best 20CV EDC

Benchmade

CPM-20CV56g$175AXIS locking

Benchmade's S30V gets upgraded to CPM-20CV in the premium Bugout variants. 20CV is M390 under a different name — same crucible, same performance, significantly better than the base steel.

AD-10Best Hard-Use S35VN

Cold Steel

CPM-S35VN170g$180Tri-Ad lock

S35VN in Cold Steel's Tri-Ad lock. If you carry a knife for hard use — not EDC tasks but actual work — the AD-10's lock is in a different category. It will not fail under loads that would collapse most production knives.

Bugout Taiga Green (2026 Seasonal)Best ELMAX Carry

Benchmade

ELMAX52g$180AXIS locking

The Bugout platform with ELMAX — a fine carbide powder steel with exceptional toughness and a uniform structure that sharpens beautifully. Seasonal production means limited availability.

Ultratech D/EBest M390 OTF

Microtech

M390110g$280

M390 in an OTF chassis — the fastest deployment format available. Microtech's machining tolerances are genuinely impressive. OTF legality varies by jurisdiction; check yours.

Mini MaliceBest Premium Compact

WE Knife

CPM-20CV96g$280Frame lock

CPM-20CV in a Spyderco-adjacent small platform. The Mini Malice splits the gap between pocket carry and working knife. Spyderco quality at a price that reflects it.

#10

Sebenza 31 SmallBest Investment Carry

Chris Reeve Knives

S45VN86g$560Integral lock (titan

S45VN (the S35VN successor) in a hand-finished titanium frame from Chris Reeve. The Sebenza is the knife that ends the upgrade cycle for most collectors. $560 for something that improves with a decade of carry.

Steel tier ranking: CPM-MagnaCut > M390/CPM-20CV > ELMAX > S45VN > CPM-S35VN in our internal tier system. Edge retention and corrosion resistance weighted equally. Toughness weighted at 60% for EDC use (you're not batoning). S30V, D2, and VG-10 did not qualify for this list — they're competent, not premium.
