Thick Washers - 3/16" x 1/16" (4 Washers)

It’s simple as: i hate ball bearings. Because of this company I was able to give my ZT0450 the internal face lift she deserved. The fit of the washers are perfect, and the general quality is high. For those wondering, a flipper is 10x better on washers (less cleaning out crap from the pivot, more hard use applications, much smoother (buttery) action). I highly recommend. Great product and a solution to a major problem.

Fast delivery and very good communication! Excellent quality!

Always a solid option

I bought the following for my Buck Onset as an experiment. I wanted to see how it responded to bronze washers, and ceramic ball bearings.

Thick Washers - 3/16" x 1/16" (4 Washers)
Thick Washers - 5mm x 1/16" (4 Washers)
5mm Ceramic Bearings: 1/16 in (12 ball)

The part dimensions were accurate, and finish was very good.

The Onset has a case lock, and normally comes with a pair of 9 ball cage bearings. The Onset bearing dimensions are: .062 thick x .383OD x .206ID. The Onset pivot pin is just under 3/16". Note that 5mm is just slightly larger than 3/16".

Both 5mm and 3/16" thick washers installed easily. But the washers added a little friction compared to the bearings. That seems to be due to the lockbar which applies significant pressure on the side of the blade. It still flipped open, but not as easily. I ended up installing the Skiff ceramic bearings instead. It flips open very easily. The 12 ball cage is probably an improvement over the Buck 9 bar cage. The 3 extra bearings provide a bit more support.

Got these washers on the spyderco smock because I hate bearings. Thought they would be a little smoother, but i haven't finished the "break in". Good thing they sent me two sets because the first two I put in resulted in blade play. Swapped them, and no more blade play. Time will tell to see how "buttery" the action gets. Still far better than bearings imo.
