Forged Blades: History and Definition

Forging is one of the oldest metalworking techniques. Unlike blades cut from standardized rolled steel, a forged blade is shaped while hot through successive strikes that align the steel’s grain in the longitudinal direction. This process, practiced for millennia around the world, gives the blade superior mechanical properties compared to a simply machined part. The blacksmith controls the temperature, pressure, and pace to achieve precise geometry and a homogeneous internal structure. The result: a living blade, each one bearing the signature of its creator.

Properties and Technical Characteristics

A forged blade stands out in several key ways:

• Optimized metallurgical structure: hot forging aligns the steel grains and eliminates internal porosity, which improves resistance to repeated bending and edge retention.
• Customized geometry: Each blacksmith develops their own blade profiles (Scandinavian, flat, concave), spine thicknesses, and heel designs. No two forged blades are exactly alike.
• Various steels: depending on the blacksmith, you’ll find carbon steel (XC75, XC100, 1084, O1), stainless steel (14C28N, N690), or laminated Damascus steel—sometimes with several hundred layers.
• Expert finishes: the blades in our catalog are delivered polished, sharpened, and deburred. They are ready for assembly without any additional preparation.

How to Choose a Forged Blade for Your Knife?

The choice of a forged blade depends on the project you have in mind and your level of experience with knife-making:

• Intended use: A carbon steel blade is best suited for hunting or bushcraft knives, while stainless steel is better suited for kitchen or marine knives.
• Desired handle style: Check the tang length (or rat tail) in relation to the thickness of the scales or block you’ll be working with. A long tang provides more surface area for gluing.
• Damascus or single-layer steel blade: Damascus steel is as much an aesthetic choice as it is a technical one. The pattern visible after tempering is unique to each piece, but sometimes requires more care to maintain.
• Budget and blacksmith: Our selection includes blacksmiths with very different styles—from sleek Scandinavian blades to intricate Damascus designs. Compare blade geometries and steel types before making your choice.

Mercorne and Forged Blades: A Rigorous Selection

For 34 years, Mercorne has selected its forged blades with the same high standards as its handle materials: each piece is evaluated for its metallurgical qualities, geometry, and finish before being added to our catalog. We work with established blacksmiths—both French and international—whose consistent production ensures uniform quality order after order. The blades are stored and shipped from our workshop in France, with careful packaging to prevent any damage to the cutting edge. Same-day shipping (for orders placed before noon), returns accepted within 15 days, free shipping on orders of €90 or more.

Frequently Asked Questions About Forged Blades

What is the difference between a forged blade and a stamped blade?

A forged blade is shaped while hot by a blacksmith, which reorganizes the metal’s internal structure and improves its mechanical properties. A machined blade (or “stock removal” blade) is produced by grinding the desired shape from a bar or sheet of rolled steel without any prior forging. Both techniques produce very high-quality blades, but forging offers a visual signature and geometric customization that cannot be replicated through machining alone.

Are Mercorne’s forged blades ready to be mounted?

Yes. All blades in our catalog are delivered with the pattern revealed (the metal is cleaned and the damask or steel pattern is highlighted), sharpened, and deburred. All you need to do is attach them to your handle and make any final edge adjustments as needed for your intended use.

Can a forged blade be paired with any handle material?

Yes, in the vast majority of cases. The only technical consideration is adapting the tang (length and thickness) to the material chosen for the handle. Stabilized wood, synthetic materials, horn, bone, or resins all work well with the blades in our selection. For special projects, Olivier can guide you toward the most suitable combination.

How do you care for a forged carbon steel blade?

Carbon steel is prone to rust if left damp. After use, wipe the blade thoroughly and apply a thin layer of mineral oil or camellia oil. A patina will form naturally over time, providing additional protection. Avoid very humid environments or prolonged immersion in water.

Is it possible to order a custom-forged blade through Mercorne?

Our catalog features only in-stock blades, selected from our partner blacksmiths. We do not offer a custom forging service. However, the diversity of our selection—in terms of length, profile, and steel—allows us to accommodate most knife-making projects. Please contact us if you have specific requirements.
