The new bearing compatibility list is now live, check it out here!
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.
I've installed these 4mm 3/64" (13 ball) bearings in multiple Knafs Lander 1 (14C28N + G10), and the bearings have really smoothed out the action every time! Every Lander 1 I've owned has felt mildly gritty out of the box, but Skiff bearings, alongside cleaning and relubricating, have always immediately and dramatically improved the action.
These bearings are very slightly smaller than the OEM Lander 1 bearings, but they have 13 balls to the OEM's 7, so the blade should be well supported. At any rate, once I torqued the pivot just to the point of centering the blade, I found that the blade moves very freely without showing a hint of side-to-side play.
I am very happy with these bearings even though they cost nearly a quarter of what the Lander 1 in 14C28N does!
