Cryogenic Knife Steel Treatment — Does It Actually Improve Performance?
Does cryogenic treatment actually improve knife performance? The science of deep-freezing steel, which alloys benefit most, and what the testing shows.
Knife Steel Comparison: D2 vs 154CM vs S30V
D2, 154CM, and S30V come up constantly in knife forums and product listings, and for good reason — each represents a distinct approach to balancing hardness, edge retention, toughness, and corrosion resistance. None of them is objectively “best.” The right choice depends on what you’re willing to trade off. Here’s an honest look at how…
MagnaCut Steel Explained — Is It Really the Best Knife Steel?
In the knife world, every few years a steel comes along that genuinely changes the conversation. CPM MagnaCut is that steel. Developed by Dr. Larrin Thomas and released in 2021, MagnaCut has taken the industry by storm — but does it live up to the hype? Let’s dive deep into the metallurgy, the performance, and…
D2 vs 14C28N Steel — Budget Knife Steel Showdown
Walk into the budget knife market and two steels dominate the conversation: D2 and Sandvik 14C28N. They’re the default choices for knives in the $30—$80 range, and for good reason. Both punch well above their price class. But they’re fundamentally different steels with different strengths — and picking the wrong one for your use case…
CPM-CruWear in Real-World Use: Why Bushcraft Knifemakers Like It
CPM CruWear didn’t start life as a knife steel. Crucible Industries developed it as a high-performance tool steel for industrial cutting and cold-work applications, where wear resistance under repeated stress matters more than anything else. Custom and semi-custom knifemakers noticed the same properties that made it valuable on a factory floor made it valuable in…
Edge Retention vs Toughness: Picking Between S30V, S35VN, and S45VN for Your Use Case
S30V, S35VN, and S45VN are close enough in chemistry that people often treat them as interchangeable — “a premium Crucible steel” and leave it at that. In practice the differences between them are real, even if they’re smaller than the gap between, say, a budget stainless and a powder-metallurgy super steel. Knowing where each one…
Toughness vs Hardness: Why These Two Knife Steel Properties Aren’t the Same
“That steel is hard, so it must hold an edge and never chip” is one of the most common misunderstandings in knife discussions, and it comes from collapsing two separate properties — hardness and toughness — into one idea. They’re related, but they’re not the same thing, and knowing the difference explains a lot about…
K390 Steel: Extreme Edge Retention for Serious Users
Blade steel is the most discussed — and misunderstood — aspect of knives. Marketing terms like “surgical stainless” obscure more than reveal. Real performance comes down to balancing four properties: edge retention, toughness, corrosion resistance, ease of sharpening. Our Top Picks for This Category We evaluated these options based on blade steel performance, ergonomics, build…
The Evolution of Crucible’s S-Series Steels: From S30V to S45VN
Few steel families illustrate the slow, deliberate process of metallurgical refinement as clearly as Crucible Industries’ S-series. S30V, S35VN, and S45VN aren’t three unrelated products competing for shelf space — they’re three generations of the same idea, each one a direct response to what knifemakers learned from using the last. S30V: Built for Cutlery From…
M390 vs 20CV: Are They Really the Same Steel?
Knife steel is the heart of any blade. Composition, heat treatment, and carbide structure determine edge retention, sharpenability, corrosion resistance, and toughness. Understanding steel helps you make informed decisions. This guide breaks down everything. Our Top Picks for This Category We evaluated these options based on blade steel performance, ergonomics, build quality, and real-world usability….
