The CJRB Feldspar is an everyday carry folding knife with a wide drop point blade in CJRB's proprietary AR-RPM9 steel. The high flat grind keeps the edge thin for slicing while the spine stays sturdy, and thumb studs plus caged ceramic bearings let it open one-handed and fall shut once the liner lock is disengaged. This version uses flat textured carbon fiber scales instead of the standard contoured ones, giving a slimmer profile and better grip with gloves. It suits daily pocket carry and light outdoor use; against rivals it stands out for its steel and deep-carry clip, though it is a liner lock rather than a crossbar or frame lock.

Owners of the Feldspar line generally praise the AR-RPM9 blade for taking a sharp edge and holding it through everyday cutting, and like the smooth bearing action. Some find the liner lock and thumb-stud-only opening less convenient than flipper or crossbar designs.
The CJRB Feldspar J1912 is a folding pocket knife with a wide drop point blade made from AR-RPM9 steel. The blade has a high flat grind that keeps the edge thin while the spine stays robust. The steel is intended to balance edge retention, corrosion resistance and ease of sharpening, and the blade has a black PVD coating.
The handle uses carbon fiber, which is temperature resistant, water resistant, non-reactive and non-conductive. This version has flat textured scales instead of the standard contoured ones. They give the knife a slimmer profile and more grip when wearing gloves.
Thumb studs open the blade with one hand, and caged ceramic ball bearings let it snap open with little pressure. To close it, disengage the liner lock and the blade falls shut into the handle. A deep-carry steel pocket clip sits low in the pocket, and a large lanyard hole fits 550 paracord or leather cordage.
