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

Improved blade deployment

I bought a Giantmouse Biblio when the knife was first launched. I liked everything about it except the blade action. Over time, I disassembled, cleaned and oiled the knife several times but I couldn't get the blade action I was hoping for. A Facebook poster mentioned Skiff Caged Bearings, pivot: 5mm, bearing: 1/16 in (11 ball) that worked for him in his Biblio. I gave it a shot and they work like a charm.

SOC Nemley

I install these Skiff bearings on all my knives and will continue to do so with every knife I purchase. These bearings are top notch and top quality when it comes to caged bearings.
These fit perfectly in my Something Obscene Compamy Nemley. They have improved the overall quality and performance of my knife. I will definitely buy more!

Let them improve your knife too!!

Excellent upgrade

The 11-ball bearings added to my GiantMouse Biblio further enhanced the action, making it just that much smoother throughout deployment. Definitely worth the money.

Pivot Hole size inconsistent

Got these in for a Kizer feist. Only one bearing fit over the pivot. The other's interior opening was too small. I had to file down the interior opening of the bearing with a diamond rod for 5 mins before it would fit, and it didn't work in the feist, the cages are too wide.

Ended up fitting in a Ganzo, for what it's worth, but that pivot thing bums me out.

Pena Mula, Berg Iron Pup, Olamic Whippersnapper

Man these bearings are a sweet upgrade over the stock ones. They fit all these knives. I noticed a big difference in the Pup, a decent difference in the Olamic, and the Mula was about the same, maybe a tad smoother. But for the price, you can’t go wrong.
