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

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!

Best bearings period

6mm fit my CKF Evo 2.0 perfect and made the action feel even better.

Awesome product

I bought a couple sets of bearings for my knives, and these are great! Smooth. I will slowly replace the bearings or washers in my knives with Skiff bearings. Thank you!
