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.

  • 22% 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

Very well made

Put the 6mm 13 ball bearings in a Green Thorn. The action didn't change at all, but it immediately fixed the centering issue. I could not get the blade centered on the stock bearings no matter what I tried, but I popped the Skiffs in and the problem completely went away.

Great quality bearings

I've installed these on my Direware Solo, older 1/4" pivot, 2mm ball, and they make the action much smoother. I'd like to upgrade the rest of my custom knives, however not all sizes are available. Hope more sizes are made available, for instance 10mm pivot opening with 1mm ball. Thank you

Great fit and finish!

I have a plastic caged ceramic bearing and a skiff in the same configuration, test fit both and noted the skiff operated smoother, I didn’t expect I would notice but I did.

Waiting on the knife to install these

Haven’t installed these 6MM-1/16-18 ball yet, waiting on the knife to arrive from overseas. However I did install skiff’s into my TwoSun Ts177 Maverick, same size as all the other 2suns except the TS313.
Also installed skiffs in my Peña mini D and Lannys clip, 5mm- 1/16 11 ball in 2 SOC mini J-capes. The list goes on and on.
Hands down, Skiffs are the best aftermarket bearings on the market! Weather it makes the action a little smoother. Or just adds a little extra lateral stability to the blade on your folding knives… Skiffs are well worth the $10-13 dollar investment for a lifetime of improved performance on your knives!
