CR4300: Michael Walker 4300 Fidus - Blue Titanium/Polished Flats

Columbia River (CRKT)

Designed by the legendary Michael Walker, the CRKT Fidus - named after the Latin word for "trustworthy" - is a sophisticated everyday carry that brings the artistry of custom knifemaking to a production-ready tool. This iteration features a striking Damascus steel clip point blade with an acid-etched finish, providing a unique visual texture that complements its high-performance edge. Deployment is exceptionally smooth and reliable, utilizing titanium thumb studs and an IKBS ball-bearing pivot to deliver the glassy action expected from a Walker design. The handle is precision-machined from titanium with a refined brushed finish, supported by a matching titanium backspacer and a decorative pivot ring that reinforces its premium construction. Every detail is engineered for long-term loyalty, including a signature titanium pocket clip equipped with a roller for effortless and secure pocket retention. Combining a minimalist aesthetic with top-tier materials, the Fidus stands as a reliable, high-end companion that embodies the precision and innovation of one of the industry’s most influential designers.

Cons: Ease of Opening, Handle Feel
Extremely stiff detent AVOID known issue!
As the description states "smooth operation" was expected. However when I received the knife and tried to open it, via the thumb stud it was extremely tight. The detent is just too stiff. I tried deferent methods and non allowed smooth operation due to the stiff Detent.
