Columbia River 2075 Shrill 4.77" Fixed Plain Dual-Edge 8Cr13MoV Gray TiN Black/Gray Resin Fiber Overlay Handle

The Columbia River 2075 Shrill is a purpose-built tactical fixed-blade boot knife designed by Matthew Lerch. The 4.77" double-edged dagger profile is cut from 8Cr13MoV stainless steel with a Gray Titanium Nitride (TiN) coating for corrosion resistance and a low-reflectance finish, hardened to 58-60 RC.

Full-tang construction runs a continuous steel backbone through the handle, where polished resin-infused fiber overlays provide grip security in a black/gray two-tone look. The blade measures 0.15" thick, keeping the knife slim and discreet for boot-top or belt carry without giving up usable working edges.

At 8.69" overall and just 4.30 oz, the Shrill is a lightweight companion suitable for utility, outdoor, and defensive roles. The plain dual-edge geometry sharpens easily on both sides.

A leather sheath with an integrated boot clip is included for secure, low-profile carry. This is a New production CRKT knife ready for everyday carry, field work, or collection display.
