CRKT 4220 Fidus (Black GRN)

Trust in every cut.

Designed by acclaimed knifemaker Michael Walker, the Fidus™ /fee-dus/ is a modern everyday carry inspired by Walker’s custom designs. Its name—derived from the Latin word fidus, meaning trustworthy and loyal—perfectly captures the spirit of a knife you can rely on day after day.

The stonewashed blade is made from 12C27 steel, striking a balance between edge retention, toughness, and easy maintenance. A textured glass-reinforced nylon handle keeps weight to a minimum while ensuring a secure grip in any condition. A thumb stud paired with IKBS™ ball bearing pivot provides fast, smooth and confident deployment.
