Quick verdict
The Herman Dragonfly is one of the broadest and most substantial folding platforms in the Herman lineup. Depending on production generation, documented examples carry approximately 3.82–3.94 in (97–100 mm) of blade, measure 8.86–8.94 in (225–227 mm) overall, and weigh from roughly 5.3 ounces in some titanium builds to more than 6 ounces in heavier configurations.
Its size is both the primary advantage and the main compromise. The wide blade provides room for an efficient primary grind, while the long, contoured Grade 5 titanium handle gives medium-large and large hands more support than the Sting, Slim, Ishtar, or Mantis. The heavier blade also produces a forceful detent break and the deeper acoustic response associated with large Herman folders.
The Dragonfly is not a discreet or lightweight EDC. It is intended for buyers who deliberately want a full-size titanium flipper with a broad blade, substantial grip, strong mechanical feedback, and a choice between practical user builds and elaborate collector configurations.

Editorial basis
This review uses current Noblie inventory specifications, exact-piece photographs and handling footage, official maker documentation, and published independent reviews from multiple production periods. Where measurements or internal components differ, those differences are identified rather than combined into one universal specification.
Dragonfly specifications have changed more than a single generic model table suggests. Published examples differ in blade length, overall length, blade width, stock thickness, weight, grind, hardness, and internal bearing construction.
The ranges below describe documented production rather than one current configuration.
| Specification | Documented Dragonfly Range | Current Noblie Examples |
|---|---|---|
| Blade length | 3.82–3.94 in (97–100 mm) | Commonly 3.82 in (97 mm) |
| Overall length | 8.86–8.94 in (225–227 mm) | Commonly 8.86 in (225 mm) |
| Closed length | 4.96–5.04 in (126–128 mm) | Commonly 5.04 in (128 mm) |
| Blade width | 1.18–1.22 in (30–31 mm) | Commonly 1.18 in (30 mm) |
| Blade thickness | About 0.154–0.205 in (3.9–5.2 mm) | Commonly 0.157–0.161 in (4.0–4.1 mm) |
| Weight | About 5.29–6.46 oz (150–183 g) | Commonly 5.43–5.93 oz (154–168 g) |
| Handle | Grade 5 titanium | May include titanium or carbon-fiber inlays, Timascus, engraving, or coatings |
| Lock | Nested Grade 5 titanium liner lock | Not a frame lock |
| Deployment | Manual flipper | Not automatic, spring-assisted, or OTF |
| Pivot | Herman custom pivot | Current production uses TORX T20 adjustment |
| Bearings | Ceramic ball bearings | Current production uses retained caged bearings |
| Country of origin | Poland | Designed and overseen by Bartosz Herman |
A note on unit conversions
This article uses direct metric-to-imperial conversions. A 97 mm blade equals approximately 3.82 inches, not 3.74 inches.
Some product listings use inconsistent or heavily rounded conversions, so the metric figure and the certificate for the exact knife should take priority.
The current Dragonfly M390 with purple titanium handle uses:
The current Dragonfly M398 Bubbles uses:
The Dragonfly MagnaCut weighs approximately 5.43 oz (154 g), making it one of the lighter current user-oriented configurations.
Earlier Dragonfly listings document larger combinations such as:
The heaviest widely cited figure, 6.46 oz (183 g), belongs to a documented M398 example built on 0.201 in (5.1 mm) blade stock. It describes that specific heavy configuration rather than the expected weight of a current titanium Dragonfly.
The buying rule
Check the exact product page, certificate, grind, hardness, and weight. “Dragonfly” identifies the platform, not one fixed specification.
The Dragonfly is not merely a longer Herman. Its character comes from the relationship between blade width, handle volume, blade mass, and internal titanium structure.
Four features define the platform:
This combination gives the Dragonfly more physical and mechanical presence than Herman’s slimmer models.
Dragonfly was historically promoted as the largest Herman model. That description is no longer sufficiently precise because Morpho, Ovium II, and other later models exceed it in certain dimensions.
A more accurate description is that Dragonfly is one of Herman’s broadest, heaviest, and most hand-filling conventional folding knives.
Other models use similar overall length differently:
The buyer is not choosing Dragonfly to minimize pocket space. The appeal is the confidence and physical feedback of a large titanium folder.
For an overview of the lineup, see our Herman Knives model guide.
The Dragonfly blade looks heavy, but broad blade stock does not automatically mean poor cutting geometry.
Cutting behavior depends on:
The Dragonfly’s approximately 1.18–1.22-inch blade width gives the primary grind enough distance to transition from a substantial spine to a relatively thin edge.
This is one reason reviewers have described well-ground examples as much better cutters than their dimensions suggest.
Some current M390 Dragonfly knives use a large-radius hollow grind.
A hollow grind removes additional material behind the edge while preserving more thickness near the spine. Because the radius is large and the blade is wide, the hollow can be shallow rather than visibly concave.
Potential advantages include:
A hollow grind is not automatically fragile. Durability depends on how thin the edge is, the sharpening angle, steel, hardness, and intended use.
Many current M398 configurations use a flat grind.
A flat grind creates a continuous wedge toward the edge. On the Dragonfly, it generally provides:
The Dragonfly M398 Entropic combines a flat-ground 0.161 in (4.1 mm) blade with a very bright stonewashed finish.
The wide profile provides:
It performs well during:
The trade-off is increased drag if a specific example is ground thick behind the edge. Steel alone cannot compensate for poor geometry.
Dragonfly examples are variously described as drop points, slight clip points, or hybrid profiles.
Most share:
The tip appears more robust than the narrow point of the Mantis, but it is still intended for cutting—not prying or twisting.
For a broader explanation of point profiles, see our knife blade shapes guide.
Published reviews from different production periods report different factory-edge experiences.
An early reviewer praised the thin grind but found the apex less sharp than expected and improved it with stones and a strop. A later reviewer praised a clean, hand-finished M398 edge produced with a fixed-angle system and diamond abrasives.
The defensible conclusion is not that Dragonfly edges are consistently dull or consistently perfect. Factory edge quality has varied by exact knife and production period. Inspect the individual edge rather than extending one review to the entire model.
Dragonfly uses a small sharpening notch, sometimes called a choil cutout.
This should not be confused with a full finger choil such as those found on some Spyderco models. The Dragonfly notch is intended to separate the cutting edge from the plunge grind and give the sharpening stone clearance near the heel.
One reviewer identified a valuable ownership issue: on some examples, the sharpening notch leaves only limited space between the edge and the plunge grind.
After multiple full sharpenings, the stone may begin contacting the plunge before it reaches the entire heel. This can create:
This is not an immediate problem on a new high-wear blade, but it matters on a knife expected to remain in use for decades.
Our knife sharpening angle guide explains bevel angles, thinning, abrasive selection, and guided-system setup in more detail.
Ergonomics are the most consistent strength across published Dragonfly reviews.
Even reviewers who normally preferred the thinner Slim or Ishtar described the Dragonfly as unusually comfortable.
The reasons are structural:
For medium hands, Dragonfly provides more space than strictly necessary but remains controllable.
The handle fills the palm rather than disappearing into it. Users who prefer compact knives may find the extra volume unnecessary.
Dragonfly makes its strongest ergonomic case for larger hands.
It provides:
The handle also resists rotation better than a narrow profile when the edge encounters dense material.
The scales are externally contoured rather than left as flat titanium slabs.
Internally, extensive pockets remove unnecessary material. This reduces weight and allows Herman to influence balance without reducing external handle volume.
Without that internal milling, the Dragonfly would be significantly heavier.
The long sculpted clip generally spreads pressure across a larger section of the palm instead of creating one concentrated hot spot.
Herman also machines relief under the clip so thicker pocket fabric can pass beneath it without excessive spring tension.
This combination helps explain why a large knife can remain comfortable during both carry and use.
Published reviews have noted:
These features do not improve steel performance. They improve the tactile and visual coherence expected from a premium knife.
Weight varies significantly across Dragonfly configurations.
| Configuration | Weight |
|---|---|
| Dragonfly MagnaCut #0450 | About 5.43 oz (154 g) |
| Dragonfly M390 Purple Titanium | 5.51 oz (156 g) |
| Dragonfly M390 Puzzle | About 5.75 oz (163 g) |
| Dragonfly M398 Entropic | 5.91 oz (167.5 g) |
| Dragonfly M398 Bubbles | 5.93 oz (168 g) |
| Heaviest documented M398 example, 5.1 mm blade stock | 6.46 oz (183 g) |
The 6.46-ounce figure comes from a heavy M398 build on 0.201 in (5.1 mm) blade stock. It should not be treated as the normal weight of current plain-titanium stock.
Variables include:
A heavy backspacer shifts the balance rearward. A thicker blade shifts it forward. Strategic internal milling can remove material from one area while leaving another intact.
A well-balanced Dragonfly should feel stable around the index-finger area rather than strongly blade-heavy or handle-heavy.
This stability helps during:
A minimalist will consider even the lightest Dragonfly heavy. A buyer accustomed to full-size titanium folders may consider the lighter configurations well balanced.
The Dragonfly’s broad blade creates more opening inertia than smaller Herman folders.
When the detent releases, the blade accelerates with a deeper and more forceful sensation than the Sting, Bee, or many Slim configurations.
Current product listings may describe the detent as medium, while reviewers often describe it as strong or forceful.
These descriptions are not necessarily contradictory. “Medium” is relative to Herman’s own production, while an owner comparing it with lighter mass-produced folders may perceive the same detent as strong.
A properly tuned Dragonfly should:
One later M398 review described the action as extremely difficult to fail: pressure builds against the detent ball before releasing decisively.
Dragonfly often sounds lower and more forceful than Slim or Ishtar.
Its acoustic character is influenced by:
The sound is often more of a resonant metallic “thunk” than the lighter ring produced by slimmer Herman models.
For a broader comparison of high-end flipper action, see Herman Knives vs Shirogorov.
Several reviewers preferred Dragonfly examples that begin falling under their own blade weight but remain controllable at intermediate positions.
With a large blade, controlled closing is safer and more useful than an excessively loose guillotine action.
The relevant quality checks are:
An early reviewer criticized a hooked flipper tab as uncomfortable and intrusive in the pocket. Later reviewers did not repeat that complaint.
Possible explanations include:
The criticism remains relevant when evaluating an older secondary-market Dragonfly, but it should not be applied automatically to current production.
Dragonfly uses a nested Grade 5 titanium liner lock, not a frame lock.
Current examples add a tungsten-carbide lock insert, tungsten-carbide stop pin, ceramic detent ball, custom T20 pivot, retained ceramic bearings, and hardened M390 bearing washers.
The carbide insert provides a hard lock interface and reduces direct titanium-on-steel galling. The hardened washers create dedicated bearing raceways rather than allowing ceramic balls to run against the softer titanium scales.
Earlier Dragonfly knives may use loose ceramic balls, different washers, and older pivot tools. Current caged bearings retain and space the balls, making routine service less hazardous.
The detailed engineering and production evolution are covered in our Herman ceramic bearing system guide. Cleaning and adjustment procedures are covered separately in our Herman knife maintenance guide.
Before you disassemble
Identify the generation first. An older loose-bearing video does not describe a current caged-bearing Dragonfly, and following it can release ceramic balls that are difficult to recover.
Dragonfly carries better than its dimensions suggest, but it never becomes pocket-neutral.
A typical current example is:
The long titanium clip is one of the model’s more consistently praised components.
Its length:
Relief milled under the clip helps it pass over:
The clip is not necessarily deep carry, so part of the handle may remain visible.
For minimalist carry, yes.
For an owner who prefers full-size titanium folders, not necessarily.
A 5.43-ounce MagnaCut configuration is materially different from a 6.46-ounce heavy M398 build. The exact configuration determines whether Dragonfly feels like a large daily user or a collector object that can be carried.
Dragonfly is a manual bearing flipper.
It is not:
The user must apply pressure to the flipper tab and overcome the detent before the blade rotates.
A decorative Dragonfly can look appropriate as a high-end dress knife, but its physical size remains unchanged.
For conservative or low-profile carry, Slim, Sting, or Bee is generally easier to manage.
Dragonfly is better suited to buyers who are comfortable with a visible, full-size folder.
The broad handle and long cutting edge work well for controlled outdoor tasks such as:
It should not replace a fixed blade for chopping, prying, batoning, or repeated dirty work around the pivot.
Steel should not be chosen independently from grind and edge geometry.
A hollow-ground M390 Dragonfly can cut differently from a flat-ground M398 version even when both are equally sharp.
MagnaCut uses a comparatively fine carbide structure and avoids the large chromium-carbide population found in many high-wear stainless steels.
At Herman’s typical 63–64 HRC, it offers:
This makes MagnaCut the strongest general recommendation for a Dragonfly that will be carried and used regularly.
Its advantage is not superior abrasive wear resistance. M390 and especially M398 can outperform it in controlled edge-retention tasks. The advantage is a better balance when the edge encounters impact, twisting, or unpredictable daily use.
See our CPM MagnaCut steel guide for the complete metallurgy and heat-treatment discussion.
M390 provides:
Earlier Dragonfly examples are often listed around 61 HRC, while current Noblie M390 examples may be specified at 62 HRC.
The current hollow-ground M390 Dragonfly is a particularly useful combination because the grind reduces cutting resistance while the steel provides long edge life.
Read our Böhler M390 steel guide for more detail.
M398 increases vanadium substantially over M390—approximately 7.2% vanadium—and develops a very high carbide volume.
That produces:
Earlier Dragonfly M398 examples may be listed around 61 HRC. Current Noblie examples are commonly specified at 62–63 HRC with deep cryogenic treatment.
M398 is best for:
It is a poor choice for twisting cuts, impacts, staples, or casual prying.
See our Böhler M398 steel guide for composition, carbide structure, and sharpening requirements.
| Configuration | Main Advantage | Main Trade-Off | Best Buyer |
|---|---|---|---|
| MagnaCut, well-supported edge | Toughness and corrosion balance | Less abrasive edge retention than M398 | Regular mixed-use EDC |
| Hollow-ground M390 | Low cutting resistance with strong edge life | Less toughness than MagnaCut | Slicing-oriented collector/user |
| Flat-ground M398 | Maximum controlled slicing wear resistance | Lower toughness and harder sharpening | Cardboard, rope, and high-wear cutting |
| Patterned steel or San Mai | Visual depth and collector value | Higher price and finish sensitivity | Collector or selective carry |
Dragonfly changes significantly when decorative materials are added.
A practical build generally combines:
This is the better choice for regular carry, boxes, workshop cutting, and daily maintenance.
Collector builds may use:
An archived Dragonfly M390 Puzzle demonstrates how engraving and patterned titanium can increase visual complexity while retaining a usable M390 blade.
The premium paid for a full-dress Dragonfly reflects:
It does not automatically buy better action or cutting performance.
A plain MagnaCut Dragonfly may be the better tool. A Timascus or patterned-steel version may be the more desirable collectible.

Secondary-market listings use labels such as:
At least one published owner review documents a Dragonfly Gen 2 marking inside the scale. However, sellers do not always apply generation terminology consistently.
Differences across Dragonfly production include:
Before purchasing, verify:
This is particularly important on the secondary market, where descriptions may combine current specifications with an older knife.
Our guide to buying Herman Knives in the USA explains exact-piece verification, inventory, shipping, and dealer considerations.
Published reviews from different years provide a useful view of recurring strengths and generation-specific weaknesses.
The most consistent positive observations are:
The repeated conclusion is that Dragonfly does not merely feel like a larger Slim or Sting. Its broader handle and heavier blade produce a different physical experience.
Later reviewers frequently praise a crisp, strong detent break with no detectable lash.
Exact-piece listings may still describe the detent as medium. Buyers sensitive to detent strength should request an action video rather than rely on a generic model description.
One early reviewer found the hooked tab uncomfortable. Later reviewers did not repeat the criticism.
This should be treated as a potential concern for an older exact piece, not a universal defect.
One early example arrived below the reviewer’s sharpness expectations. A later M398 example was praised for its hand-finished edge.
The evidence supports individual or generational variation, not a model-wide conclusion.
The limited clearance between the edge and plunge grind on some examples is a credible long-term concern. It will matter most after repeated full sharpenings.
Older loose-bearing examples are substantially less convenient to service than current caged-bearing knives.
The buyer should identify the mechanism before following an old disassembly video.
| Feature | Dragonfly | Mantis |

Choose Big Sting for:
Ovium II uses a longer blade and emphasizes blade-to-handle efficiency.
Dragonfly prioritizes blade width, handle fullness, and broad-platform control. Ovium II prioritizes maximum reach, a more efficient folded package, and lower weight in some configurations.
Ishtar is lighter, narrower, and more Persian-inspired.
Dragonfly is broader and more stable during general cutting.

Dragonfly is best suited to:
Consider another Herman when:
| Pros | Cons |
|---|---|
| Excellent ergonomics for larger hands | Heavy compared with most EDC folders |
| Broad working blade | Large pocket footprint |
| Choice of hollow and flat grinds | Not discreet in conservative environments |
| Strong and repeatable flipper deployment | Specifications vary substantially by generation |
| Deeper Herman acoustic response | Older knives may use loose ceramic balls |
| Controlled closing action | Some early flipper tabs may feel uncomfortable |
| Effective sculpted titanium clip | Sharpening-notch clearance can be limited |
| Extensive internal weight reduction | Factory edge reports vary |
| Nested titanium liner lock | Decorative finishes show carry wear |
| Current caged ceramic bearing system | Heavy configurations can exceed 6 ounces |
| Choice of MagnaCut, M390, M398, and patterned steels | Exact pivot tool should remain with the knife |
| Available as both user and collector configurations | Premium price partly reflects materials and artistry |
| High level of machining and finishing detail | — |
The Herman Dragonfly should not be purchased merely because it is one of the larger Herman folders. It should be purchased because the buyer specifically wants what its broad platform provides: more handle volume, more blade width, stronger in-hand stability, deeper mechanical feedback, and a more forceful acoustic response.
Its size creates real advantages for large-handed users and for cutting tasks that benefit from a broad blade and long working edge.
The compromises are equally real. Dragonfly is heavier, wider, and less discreet than Sting, Slim, Bee, Ishtar, or Mantis.
The exact configuration also matters more than the model name. A hollow-ground M390 Dragonfly is a different cutting tool from a thick, flat-ground M398 example. A 5.43-ounce MagnaCut user is a different ownership proposition from a 6-ounce-plus collector build.
The Dragonfly is therefore not the universally best Herman. It is the best fit for a buyer who has already decided that a substantial full-size titanium folder is an advantage rather than a compromise.
Compare current exact-piece Dragonfly configurations, steels, grinds, and weights in our Herman Knives inventory.
Documented examples range from approximately 3.82 to 3.94 inches (97–100 mm) of blade and 8.86 to 8.94 inches (225–227 mm) overall.
Current Noblie titanium examples generally weigh about 5.43–5.93 ounces (154–168 g). A documented heavy M398 build on 5.1 mm blade stock reaches 6.46 ounces (183 g).
Yes, for users who deliberately prefer large titanium folders. It is not a minimalist or discreet EDC.
Yes. The long, broad, contoured handle is one of the model’s main advantages for large and extra-large hands.
No. It uses a nested Grade 5 titanium liner lock.
No. It is a manual flipper operating on ceramic bearings. The user must overcome the detent with the flipper tab.
It depends on the exact knife. Current M390 examples may use a large-radius hollow grind, while many current M398 versions use a flat grind.
MagnaCut is the best balanced user choice. M390 works well for collector/user crossover. M398 is suited to maximum abrasive edge retention during controlled slicing.
Herman has revised blade dimensions, thickness, bearings, washers, pivots, flipper geometry, and handle construction over multiple production generations.
Current production does. Earlier examples may use loose ceramic balls.
Some knives have internal generation markings, but secondary-market terminology is not always consistent. The certificate and exact mechanical specifications are more reliable than the generation label alone.
It is designed, machined, assembled, and hand-finished in Poland under Bartosz Herman’s supervision.
