The new bearing compatibility list is now live, check it out here!

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.

  • 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

Cage Bearings - Pivot: 5mm<br>Ceramic Bearings: 3/64" (15 ball)

Perhaps not world-shattering, but quite nice nevertheless

[This review was originally submitted under the wrong product page]

I ordered Cage Bearings - Pivot: 5mm Ceramic Bearings: 3/64" (15 ball) to replace the stock bearings in my Kizer Sparrow (OD: 9.6mm, ID: 5mm, thickness: 1.2mm for both the micarta and Ti versions according to Kizer support). I found this set of Skiff bearings to be a good fit, though for anybody who cares about the nitty gritty, I'll note that 1. the Skiffs leave a ~0.55mm gap around its outer edge and the edge of the bearing cutout and 2. the balls of the Skiff bearings sit roughly 9% closer to the center than the balls of the stock bearings. I am not an expert on bearings, but I would guess neither significantly affects the function of a pocket knife. Also, each Skiff has 5 more balls than the stock; I'd guess this lends the blade more support.

I installed the Skiffs into a brand new Kizer Sparrow and was pretty impressed with their performance. Take the following with a grain of salt since two knives of the same model may have significant variance in detent strength, etc., but whereas my older Sparrow could never fully deploy when "push-buttoned" despite being broken in and having smoothed bearing and detent tracks, my brand new Sparrow with Skiffs easily deploys regardless of the method I employ. I believe I lubricated both knives the same way (drop of mineral oil on the pivot and detent ball plus dry bearings) and torqued both equally, but again, grain of salt. So far, the action with Skiffs has felt wonderfully smooth and maybe even floaty, and I only expect it to improve as things wear in.

I highly recommend this set of Skiff bearings! I would also like to take a moment to commend Mr. Steven Skiff for his patient support: in a haze of illness, I managed to order the wrong set of bearings *twice*, but Mr. Skiff sorted me out with an easy return for my first order and an extremely prompt modification to my second order, even going so far as to apply a small discount since the bearings I needed were slightly pricier than the set I had paid for. Thank you!

2 down 17 to go.

I’ve only installed 2 sets of the 19 I ordered one on a $100 civivi and one was a $1000 Microtech both made a noticeable improvement.




Great addition!
