A Herman knife can be the same model and still be a very different purchase depending on the blade material. A Sting in CPM MagnaCut is aimed at a different owner than a Sting with a mirror-polished Damasteel blade. An M398 Slim emphasizes wear resistance and long slicing life, while a Damacore Full Dress Slim combines a dedicated cutting core with patterned outer layers and far more collector-oriented finishing.
Current Herman Knives inventory at Noblie includes CPM MagnaCut, Böhler M390, Böhler M398 and several Damasteel patterns, with higher-end configurations also appearing in Damacore. These materials do not form a simple good-better-best ladder. Each one solves a different problem, and the exact piece matters more than the alloy name.
Noblie is an authorized Herman Knives dealer working with individual exact pieces rather than generic stock examples. This guide combines steelmaker data with specifications from knives currently in our inventory, and keeps measurable material properties separate from collector preference.
For a Herman that will actually be carried, CPM MagnaCut offers the broadest overall balance of toughness, corrosion resistance and edge performance in the current lineup. Choose M390 for proven premium stainless performance and very high polishability. Choose M398 when abrasive edge retention outranks toughness and sharpening speed. Choose Damasteel when the blade pattern is meant to be a central part of the knife. Choose Damacore when the layered construction itself is what you are collecting.
| Blade material | Construction | Main reason to choose it | Trade-off | Typical Herman buyer |
|---|---|---|---|---|
| CPM MagnaCut | PM stainless monosteel | Best balance of toughness, corrosion resistance and edge performance | Does not maximize abrasive wear resistance | Owner who intends to carry and use the knife |
| Böhler M390 | PM stainless monosteel | Wear resistance, corrosion resistance and very high polishability | Less tough than MagnaCut; slower to sharpen | Premium EDC or dress-folder buyer |
| Böhler M398 | High-wear PM stainless monosteel | Highest abrasive edge retention among these monosteels | Lower toughness and slow material removal when sharpening | Experienced user prioritizing slicing life |
| Damasteel DS93X | PM stainless patterned steel | Functional stainless blade with a pattern in the material itself | Cost reflects material and finishing, not only cutting performance | Collector who still wants a usable blade |
| Damacore | Cored PM stainless patterned construction | Dedicated cutting core inside patterned outer layers | Cost and complexity rise sharply; usually a Full Dress build | Collector seeking a material-focused flagship |
This is a buying guide rather than a laboratory ranking. Heat treatment, hardness, blade geometry and edge angle change real-world results substantially, and the sections below explain why.
Herman does not assign one permanent steel to each model. A Slim, Sting, Bee, Ishtar, Mantis or Dragonfly can appear in different materials across individual builds and production periods. That is one reason the exact piece matters so much with this maker, and why our Herman Knives model guide separates the platform decision from the material decision.
Conventional blade steels in current inventory:
Patterned blades in current inventory:
One point causes constant confusion: Fafnir, Rose, Jörmungandr and Odin’s Eye are pattern names, not steel grades. Two blades with different pattern names can be the same steel system. The underlying material has to be identified separately from the pattern, in the same way that Puzzle, Tesseract and Oerlikon describe handle treatments rather than a single manufacturing process.
Damasteel gives a Herman blade something MagnaCut, M390 and M398 cannot: a pattern that runs through the blade material and becomes visible after grinding and etching. That visual character suits Herman’s Half Dress and Full Dress builds, where the blade may be paired with Timascus, Fat Carbon or engraved titanium.
It should not be described as expensive decoration, though. The material is a hardened stainless steel engineered for cutting.
Damasteel DS93X is a powder-metallurgy stainless Damascus patterned steel built from two hardenable martensitic stainless grades, RWL34 and PMC27. Damasteel describes it as combining corrosion resistance with high strength and superior edge properties, and lists it as suitable for edge tools such as knives.
For the buyer, the practical implications are:
If you want the wider context on how this differs from forged and canister Damascus, see our guide to types of Damascus steel.
Availability changes constantly because Herman produces limited combinations rather than a permanent catalog. At the time of writing, our inventory includes Damasteel examples across the Sting, Slim and Ovium II families, in Jörmungandr, Fafnir, Svavner and Rose patterns. Current examples are typically listed at around 61 HRC with deep cryogenic treatment, mirror-polished flat grinds being common on the dress builds.
Those figures describe current exact pieces. They are not a universal hardness rule for every Herman Damasteel blade ever produced, so check the individual listing.
Not in the way buyers sometimes assume. A Jörmungandr blade is not inherently a better cutter than Fafnir, Rose or Svavner because the visible pattern differs. Within the same steel family, pattern generation changes how the constituent alloys are arranged visually. Grinding, heat treatment, edge geometry and sharpening have far more influence on how the knife cuts.
This matters commercially, because pattern can move price and desirability a long way while moving edge behavior very little.
Yes. The steel is corrosion resistant and holds an edge well, and a Damasteel Sting with a Grade 5 titanium handle is entirely usable. The steel does not become fragile because the knife is attractive.
The real question is whether the complete configuration suits daily carry. A mirror-polished Damasteel Slim on a full Timascus handle cuts perfectly well, but most owners handle it more carefully, because cosmetic wear on a collector configuration is harder to live with and far harder to reverse than a scuff on a stonewashed user.
The premium does not come from edge retention. It comes from several directions at once:
That last point is why calculating the whole price gap as a “Damasteel surcharge” is misleading. Damasteel pieces usually arrive as Half Dress or Full Dress builds rather than as otherwise identical knives with a different blade. You are comparing two configurations, not two steels. Our note on whether Herman knives are worth it covers the same reasoning across the rest of the lineup.
Damacore is often grouped casually with Damasteel because both come from Damasteel AB and both show a Damascus pattern. Structurally they are not the same thing.
Damacore is a cored powder-metallurgy stainless patterned steel. Rather than carrying the same construction through the blade, it places a distinct steel core between patterned stainless outer layers. Damasteel currently produces two grades:
The outer layers create the visible pattern. The central steel becomes particularly relevant at the cutting edge once the blade is ground.
A Herman Slim Full Dress currently in stock uses a Damacore DC18N blade in the Odin’s Eye pattern: N11X core, RWL34 and PMC27 outer layers, 61 HRC, deep cryogenic treatment, flat grind, mirror-polished finish. The knife pairs that blade with a Black Timascus handle, clip and backspacer.
That configuration shows why Damacore should not be read as a steel upgrade in isolation. It is being used as part of an entire Full Dress material concept.
| Feature | Damasteel DS93X | Damacore |
|---|---|---|
| Construction | Patterned PM stainless made from RWL34 and PMC27 | Dedicated core surrounded by patterned RWL34 and PMC27 layers |
| Separate cutting core | No | Yes — N11X in DC18N, RWL34 in DC21R |
| Where the pattern sits | Through the blade material, revealed by etching | In the outer layers surrounding the core |
| Current Herman examples | Sting, Slim and Ovium II in Jörmungandr, Fafnir, Svavner, Rose | Slim Full Dress, DC18N in Odin’s Eye |
| Typical role in the lineup | Premium, Half Dress and Full Dress | Highest-end material-focused Full Dress builds |
Damacore is not simply better Damasteel. It is a different construction. For a buyer who wants the strongest visual Damascus identity, standard Damasteel already does the job. Damacore becomes compelling when the layered metallurgy itself is part of what you want to own.
If the goal is to use a Herman regularly rather than maximize visual rarity, MagnaCut is the most rational starting point. Its metallurgy avoids chromium carbides in the heat-treated structure and relies instead on smaller vanadium and niobium carbides, which is why it delivers high corrosion resistance, strong toughness and useful wear resistance at the same time. Our MagnaCut, M390 and Vanax comparison covers that metallurgy in detail.
Herman folders are precision cutting tools rather than impact-oriented survival knives, but toughness still matters. A thin, efficient edge benefits from a steel that supports fine geometry without relying on extreme carbide volume. Sweat, humidity, food residue and routine pocket carry all reward high corrosion resistance as well.
Current Herman MagnaCut examples include blades hardened to 63–64 HRC with deep cryogenic treatment. Read that hardness together with the grind rather than as a standalone quality number.
Choose MagnaCut if you intend to carry the knife regularly, value edge stability and toughness, want very strong corrosion resistance, and prefer balanced performance over maximum wear resistance. For most buyers this is the most practical steel in the current lineup, and the Bee in MagnaCut is a good illustration of the pairing.
M390 has been a defining premium-folder steel for years and remains relevant. Böhler describes M390 MICROCLEAN as a powder-metallurgy corrosion-resistant martensitic chromium steel with very high wear resistance, good corrosion resistance and very high polishability, at a nominal 1.90% carbon, 20% chromium and 4% vanadium.
Those characteristics fit Herman particularly well. The workshop frequently combines precise blade work with polished or visually refined finishes, and polishability is directly useful in that environment. Current Herman M390 examples are commonly listed around 61 HRC.
Choose M390 when abrasive cutting life matters more to you than toughness margin, when you want a highly refined polished blade, or when you already know and like how M390 sharpens. There is no reason to reject an otherwise ideal Herman because it uses M390 rather than MagnaCut — the complete knife still matters more than the alloy name.
M398 is the specialist of the group. Böhler developed it as a higher-wear relative of M390: carbon rises from 1.90% to 2.70%, while vanadium increases from 4.0% to 7.2%. Böhler also states directly that M398 offers higher wear resistance than M390. In independent knife testing, Knife Steel Nerds found very high slicing edge retention but very low toughness in its test protocol, and noted that M398 is more difficult to grind and sharpen than M390.
A high-wear steel is most useful when the knife is designed to cut efficiently, and Herman pairs M398 with refined geometry rather than thick hard-use construction. A current M398 Slim runs 62–63 HRC with deep cryogenic treatment, a large-radius hollow grind and 3.3 mm blade stock. A hollow-ground premium folder working through cardboard, packaging and rope takes real advantage of that wear resistance without being asked to do impact work the alloy was never optimized for.
Is M398 better than M390? For wear resistance, yes. As an overall knife steel, not automatically — it trades toughness for carbide volume and it is slower to sharpen. The useful question is whether you want what M398 is optimized to provide. If you cut abrasive materials often and already own diamond or CBN abrasives, it is compelling. If you want a more forgiving premium folder, M390 or MagnaCut make more sense. Our dedicated M398 steel guide goes deeper into the heat treatment and testing data.
Blade-steel discussion tends to overweight alloy selection, because the steel name is the easiest thing to put in a specification table. A finished knife does not cut with a composition chart. It cuts with an edge geometry made from heat-treated steel.
At minimum, weigh six factors together: blade steel, actual hardness and heat treatment, primary grind, thickness behind the edge, sharpening angle, and blade finish relative to intended use.
Current inventory makes the point. An M398 Slim at 62–63 HRC uses a large-radius hollow grind. A Damasteel Sting at 61 HRC uses a flat grind. A MagnaCut Bee uses a flat grind at higher hardness. These knives cannot be ranked accurately by steel name while ignoring very different blade platforms. The steel sets the performance envelope; the geometry decides how much of that envelope reaches the material being cut. Our knife steel chart compares the alloys directly, but the same caveat applies there.
High corrosion resistance, strong toughness, good edge retention, fine-edge stability and reasonable maintenance. If two otherwise comparable Herman knives appeal equally and one is MagnaCut, that is the one I would point a using owner toward.
Relevant for cardboard, fibrous packaging, rope and repeated utility slicing. Use it as a cutting steel, not as license for prying or lateral loading.
A middle ground between MagnaCut’s balance and M398’s wear emphasis, and especially attractive when the exact knife has a polished or dress-oriented finish.
Choose it when the blade pattern should form part of the knife’s identity. You are paying for visual and manufacturing value that does not translate linearly into more cardboard cut per sharpening.
A DC18N blade with an N11X core and RWL34/PMC27 patterned sides has a materially different architecture from both a monosteel and standard Damasteel. In a Full Dress build, that difference is the point.
Blade steel and blade finish are related but separate choices. A conventional MagnaCut, M390 or M398 blade may be stonewashed, shiny stonewashed, satin finished, mirror polished or coated. Damasteel and Damacore need additional surface work, because the patterned structure has to be revealed and presented deliberately, which is why current patterned pieces so often arrive mirror polished.
Finish affects more than appearance. A stonewashed user hides minor wear easily. A mirror-polished patterned blade emphasizes the steel and the pattern, and shows handling marks in return. In daily ownership that difference usually outweighs a small theoretical gap in edge retention. Our knife blade finishes guide covers the trade-offs finish by finish.
All five material categories can be sharpened and maintained as working knives, but not with equal ease.
Measure the factory bevel rather than guessing at it, particularly on an expensive Half Dress or Full Dress configuration. For pivot, detent and lock care alongside edge work, see our Herman knife maintenance guide.
Yes, on selected premium and collector-oriented folders. Current examples include Sting, Slim and Ovium II models in patterns such as Jörmungandr, Fafnir, Svavner and Rose.
Availability changes, but current inventory includes Damasteel examples in the Sting, Slim and Ovium II families. Other models and patterns appear in later production, so the exact-piece listing is more reliable than assuming a permanent steel option per model.
Yes. Damasteel DS93X is a functional stainless patterned knife steel rather than a display-only material. The greater practical concern is protecting a costly mirror-polished or Full Dress configuration from cosmetic damage.
You are paying for more than the steel. Patterned material, additional finishing, polishing and etching all add cost, and Herman frequently combines Damasteel with expensive handle materials in Half Dress and Full Dress builds.
Damasteel DS93X combines patterned RWL34 and PMC27 throughout the blade material. Damacore places a separate central core inside patterned RWL34/PMC27 outer layers: DC18N uses an N11X core, DC21R uses an RWL34 core.
Yes, and more specifically a cored stainless Damascus patterned steel. The core-and-outer-layer architecture is what distinguishes it from standard DS93X.
MagnaCut is the better all-around choice for most owners because it combines toughness, corrosion resistance and useful edge retention. M398 is better when maximum abrasive wear resistance and long slicing life are the priority.
M398 has higher wear resistance, confirmed by Böhler’s own material data. It also gives up toughness and is more demanding to sharpen, which makes it more specialized rather than universally better.
MagnaCut, taking ownership as a whole rather than sharpening speed alone. It combines excellent corrosion resistance with comparatively strong toughness and manageable maintenance.
Among MagnaCut, M390 and M398, M398 is the edge-retention specialist for abrasive slicing. Actual edge life still depends on hardness, edge geometry, sharpening angle and what is being cut.
It can raise collector interest, particularly when the pattern is paired with Timascus, engraving or unusual titanium work. It does not guarantee higher resale value: condition, model, rarity, completeness and current demand all still apply.
There is no single best Herman blade steel, because these materials serve different owners.
Choose CPM MagnaCut for the strongest overall balance and a Herman you expect to carry. Choose Böhler M390 for proven premium stainless performance and excellent polishability. Choose Böhler M398 when long abrasive edge retention outweighs toughness and sharpening speed. Choose Damasteel when you want a functional stainless Damascus blade whose pattern is central to the knife. Choose Damacore when the layered construction itself is part of the appeal.
Above all, do not choose a Herman from the steel name alone. Pick the model and blade geometry first, then compare steel, heat treatment, grind, finish and exact configuration. A well-chosen MagnaCut Herman is not a lesser knife because an M398 or Damacore version costs more, and a Damasteel or Damacore Herman is not just a more expensive route to the same cutting performance. They are different interpretations of the same premium folding platform.
