420A is a corrosion-resistant stainless steel with a lower carbon content than higher alloy knife steels. Its strengths lie in corrosion resistance, toughness, and ease of maintenance.

Three key characteristics of the steel: Edge Retention, Rust Resistance, and Sharpenability

Edge Retention: low to medium
★★☆☆☆
The lower carbon content limits hardness and wear resistance.

Rust Resistance: high
★★★★☆
The chromium content provides good corrosion resistance.

Sharpenability: very good
★★★★★
The comparatively low wear resistance allows for easy resharpening.

Areas of Application

Everyday knives: The high ease of maintenance makes 420A suitable for simple cutting tasks.

Knives with moisture contact: Corrosion resistance is a significant advantage of this steel.
