Knife Technology

Forging Process

Arcos forged knives are made from a single piece of NITRUM stainless steel, heated to over 1,000 degrees Celsius and shaped under high-pressure dies. This process creates a dense, uniform molecular structure that gives forged knives their exceptional strength, balance, and edge retention.

Stamping Process

Stamped knives are precision-cut from sheets of high-quality stainless steel using hydraulic presses. The blades undergo the same heat treatment and tempering process as forged knives, ensuring excellent edge performance at a more accessible price point.

NITRUM Steel

Arcos' proprietary NITRUM steel is enriched with nitrogen during the smelting process. This results in a blade that is harder, more corrosion-resistant, and holds its edge longer than conventional stainless steel.

Heat Treatment

Every Arcos blade undergoes a precise heat treatment cycle: heating to the optimal temperature, rapid quenching, and controlled tempering. This process achieves the ideal balance of hardness (typically 55 to 58 HRC) and flexibility.

Edge Geometry

Each knife type features a blade geometry optimized for its intended use. Chef's knives have a curved profile for rocking cuts, while santoku knives feature a flatter profile for push-cutting. Edge angles are precision-ground to ensure optimal cutting performance.
