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.

You make a great product and have wonderful customer service. Thank you very much and keep up the good work!
I reached out to ask what bearings would fit my real steel knife. Customer service responded within hours with a link to the bearings. Fit is perfect and she is so smooth now. I will be buying more . Thanks Skiff!
I have over 50 knives. 90 percent of them run on skiff barrings or skiff washers!!
Great experience as always with Skiff. There was a slight mixup with USPS making a shipping error and Steve was on top of getting me squared away very quickly.
Great business that cares about its customers, and no better source for your knife bearing needs!
