Quick Verdict
The CJRB Riff J1928 is a rugged button-lock folding knife designed for heavier EDC use. Featuring a 3.47" AR-RPM9 steel blade with stone wash finish and flat grind, it offers solid edge retention and durability. The oversized button lock, full steel liners, and chunky Micarta/G10 scales provide confident handling. Smooth ceramic ball bearings ensure snappy deployment via flipper tab. At 150g, it's a substantial but capable work knife that fills the gap for users wanting a hard-use button-lock folder.
What We Like
- Durable AR-RPM9 powder steel with HRC59-61 hardness
- Reliable oversized button lock with steel liners
- Smooth ceramic ball bearing pivot action
- Versatile drop point blade profile
- Dual handle options (Micarta or G10) for grip preference
Considerations
- Heavier than typical EDC folders at 150g
- Larger 8.19" overall length may limit pocket carry
- Button lock not ambidextrous-friendly
Overview
Description:
As our recent button-lock models have become increasingly popular we’ve noticed a lack of harder-use models on the market that feature a button-lock. Enter the Riff, a rugged reliable tool with an oversized button lock and a blade designed to tackle the jobs that a regular EDC knife may struggle with. The Riff features a 3.5” clip point blade in our proprietary AR-RPM9 steel, full steel liners, and chunky scales in either OD Micarta or Black G10. This knife snaps open on smooth ceramic bearings and can be actuated using either the flipper or the large fuller that runs the full length of the blade, making this knife easy to operate, even in cold weather or with gloves.
