SiWi™ Fixed Knife | CRKT®

Canada's Source for Tactical Fixed Blades

Compact Strength, Combat Proven

The CRKT Siwi™ is a tactical fixed blade born from battlefield experience. Designed by retired Sergeant Major Darrin Sirois and refined by knife expert Chris Williams, it delivers compact power and mission-ready reliability for professional use.

Secure Grip and Enhanced Protection

Built with a full tang SK5 carbon steel blade, the Siwi™ offers excellent edge retention and durability. Its black corrosion-resistant coating adds stealth and protection, while the G10 handle provides confident grip in all conditions.

Ready for Duty

The included thermoplastic sheath offers multiple mounting options for belt, pack, or vest carry. Compact enough for everyday use, yet tough enough for tactical environments, the Siwi™ is forged by war and refined for action.
