Arcus — Compact Strength. Controlled Precision.

The Arcus is built for the moments that demand control.
Its drop point blade and flat grind bevels strike the perfect balance between strength and precision — designed for versatility across field, outdoor, and everyday tasks. Compact, balanced, and purpose-driven, the Arcus bridges the gap between field utility and everyday carry. Whether it’s tackling the unpredictable or handling fine detail work, the Arcus is built to move with you, not slow you down.

The forward finger ring delivers solid grip and precision for controlled, up-close work — allowing seamless transitions between power and finesse. Pronounced jimping along the spine provides confident thumb purchase, while the deep choil and contoured handle keep the blade secure and natural in the hand under any condition.

Forged from Böhler M390 stainless steel, the Arcus brings form and function together in a refined, purpose-driven design built for the field. Finished in a Dark Stonewash, it carries the same rugged precision and toughness that define the Sinners & Stone lineup.

Available in its skeletonized configuration for maximum weight reduction, or with optional G10 scales in OD Green or Black, complete with matching hardware for a secure, enhanced grip setup. Each configuration is assembled and finished to order.

Comes standard with a custom-fit Kydex sheath and belt clip, designed for both vertical and horizontal mounting (standard vertical or scout carry).
