Swapping to Skiff Workshop bearings is one of the most noticeable upgrades you can make to a folding knife — more blade support, less pivot tightening required, and a smoother feel from the first open. Designed and made in the USA.
Skiff Workshop cage bearings are CNC machined from solid phosphor bronze, an alloy valued for its strength, corrosion resistance, and naturally self-lubricating properties. Each cage is designed to hold more balls around the pivot than standard bearings, distributing load evenly and keeping the blade stable under use.
The balls are Grade 5 silicon nitride ceramic, made to within 5 millionths of an inch of perfect roundness. Harder and lighter than steel, ceramic balls generate less friction and maintain consistent performance over time. The balls are captured in the cage and remain free-floating inside for smooth, consistent rotation.

Bought these for my vosteed porcupine (original). They turned out to be a 1:1 size i really appreciate skiff bearings and love upgrading my knives with them. After re-assembling the knife i noticed a slight wobble in the blade but it's probably just the knife.
Bought these for my vosteed porcupine. The ceramic balls are slightly too thin and now the blade wobbles slightly. These are supposed to be compatible. I think I can fix it by adding 0.2 mm washers because the original bearings have a thickness of 1.6 mm.
Well built, solid construction and fit as expected
Quick and easy way to bring life to your knife! Easy install, immediately noticeable, quick delivery, and only $15. Super happy with all of it. Will probably order again for a couple other knives soon.
