Forged chef's knife nitrogen steel 20 cm Signature 32 Dumas

Forged chef's knife 20 cm Signature by 32 Dumas

The chef's knife from the special Signature series is the ultimate expression of the know-how of 32 Dumas, one of the oldest and most prestigious cutlery houses in Thiers, the French capital of cutlery. With origins dating back to 1532 —hence the "32" in its name— this manufacturer, today part of Rousselon Dumas Sabatier, has spent almost five centuries perfecting the art of kitchen cutlery. The Signature collection brings that legacy together in a 20 cm knife designed for professionals and lovers of good cooking who seek precision, balance and elegance in every cut.

100% forged: a single piece of steel

Each Signature knife is forged entirely from a single steel billet that shapes the blade, the bolster (mitre) and the tang. This traditional construction, far more demanding than simple stamping, guarantees a perfectly balanced knife in the hand, strong and durable. The process follows the classic stages of Thiers fine cutlery: drawing out the billet, stamping, trimming the final shape, drilling the tang, grinding and hand-polishing, and a careful final sharpening.

Technical features

• 20 cm blade in French 4116N stainless steel reinforced with nitrogen, with a hardness of 58-60 HRC that combines edge retention, strength and ease of re-sharpening.
• Hand-sharpened at a combined 25° angle. The hand-sharpening technique of 32 Dumas has been certified as «very good» by the independent CATRA institute for cutting power and abrasion resistance, which translates into an edge life longer than that of conventional sharpening.
• 4 mm stainless steel rivets, discreet and elegant.
• Faceted mitre extended by a concave guard and an oblique handle end, giving a contemporary design, finger protection and a firm, comfortable grip.
• Made entirely in France (Thiers).

Two handle finishes to choose from

The Signature knife is offered in two handle versions, each with its own character:

Recommended use

The 20 cm chef's knife is the most versatile tool in any professional kitchen. Its wide, rigid blade lets you chop, mince, carve and cut all kinds of ingredients with precision: vegetables, herbs, meats and fish. The height of the blade makes rocking cuts on the board easier and protects your knuckles, while the fine tip allows detailed work. It is the go-to knife that no cook's kit should be without.

Care of the knife

To preserve the edge and the beauty of the blade and handle, we recommend washing the knife by hand with warm water and drying it immediately, avoiding the dishwasher. Periodic sharpening with a steel or stone will keep its cutting performance for years.

French quality and heritage

Choosing a Signature knife by 32 Dumas means acquiring a piece with almost 500 years of history behind it, forged in the cradle of French cutlery. Tradition, noble materials and a modern design come together in a tool of excellence, balanced and durable, worthy of the most demanding professionals.
