Improved my knife

Installed these Skiff ceramic bearings in my Spyderco domino. These bearings are a vast improvement over the original ones that were in the knife. Knife opens and closes a lot easier, no side to side blade play and don't have to keep adjusting the pivot. This is an excellent product,plan on purchasing more of these in the future.

Website compatibility page was very helpful when ordering, items were well packaged, shipping was fast. The bearings are a great upgrade for most knives. Thanks for making these available.

Great Product - Gives Confidence

Excellent product. Have bought and installed several into my nice pocket knives. Always fit and work properly. Provides confidence that the action and centering on your pocket knife will perform optimally.

Works in Drop/Terzuola ATCF

The Drop / Massdrop / Terzuola ATCF is apparently a small batch knife, so I couldn't find it in any of the Skiff compatibility lists. The 1/4" 13 ball 1/16" ball set works perfectly. No difference in assembly, no blade play in any direction. Perfect, would recommend.
