Cage bearings that allow more balls to be placed around the knife pivot than standard cage bearings. Which provides more support for the blade and decreasing stress on each ball. The ceramic balls are captured in the disc but are still free floating to prevent binding.
Includes Grade 5 ceramic bearings pre-installed.
- Increased blade support over caged bearings of same size
- Improved ball pathing around pivot
- Less pivot screw tightening required
- CNC machined from solid phosphor bronze

10/10
I ordered several different sets of skiffs to upgrade several different knives from the standard bearings they came with. I could tell a difference immediately. The action was smoother. The skiffs made the knives feel more sturdy. It is definitely worth purchasing this upgrade for your knives.
