L'Alios - registered design & Trademark

Alios takes its name from the mineral-rich alios layers found in the Arcachon Basin.
Developed in collaboration with Robert Beillonnet, two-time Meilleur Ouvrier de France, this elegant folding knife features a rounded tip inspired by the traditional blades used by fishermen at sea.

What truly sets Alios apart is its ingenious rear rocker lock mechanism — a rare and intuitive system that combines safety, precision, and mechanical elegance.

Discover how the locking system works here.

Each knife is presented in a custom-designed cardboard box, complete with a calf leather sheath and a certificate of authenticity.

🇫🇷 100% handcrafted in our workshop in Bidart, in the heart of the Basque Country.

Fabrics

Handle

Each Alios knife is available in a selection of nine noble woods, carefully chosen for their beauty, character, and durability:

Juniper, Ebony, Morta (fossilized oak), Douelle (oak from wine barrels), Wenge, Olivewood, Birch, Pistachio, and a Juniper model with ebony bolster.

These natural materials are shaped and finished by hand to highlight their unique patterns and tactile warmth. Over time, the handle will develop a rich, natural patina, making every Alios knife truly one of a kind.

Blade Options

Choose from five exceptional steels, each offering a unique combination of performance, aesthetics, and tradition:

12C27 Sandvik Stainless Steel
A premium stainless steel, rich in chromium and carbon, known for its excellent cutting edge, corrosion resistance, and easy maintenance.
XC75 Carbon Steel
The classic steel of past generations. Easy to sharpen and offering a traditional look and feel, it will naturally develop a patina but requires careful drying after each use to avoid oxidation.
RWL34 Stainless Steel
An ultra-pure, high-performance steel produced through powder metallurgy. Durable, resilient, and corrosion-resistant, with outstanding edge retention.
VG10 / Suminagashi Damascus
A VG10 core encased in 33 layers of Damascus steel on each side. Beautifully layered and extremely sharp, this steel offers an ideal balance of strength and finesse.
160-Layer Stainless Damascus
A blend of RWL34 (bright layers) and PMC27 (dark layers), forge-welded at 1220°C, then hammered, folded, and stretched multiple times.
This artisanal steel is among the finest in the world — a true masterpiece of modern metallurgy.

Maintenance

To preserve the beauty and performance of your Alios knife:

Wash the blade only with warm, soapy water using the soft side of a sponge.
Dry the knife carefully with a soft cloth.
Avoid soaking the knife and never use abrasive cleaners.

For wooden handles, occasionally apply a drop of colorless vegetable or mineral oil (never olive oil) to keep the wood nourished and protected.

Not dishwasher safe.
