I have only had a single use for the gauge so far. It worked perfectly and the Skiff bearings fit as well.

Great upgrade tool!
Snagged one to figure out which Thick Washers I need for a knife that's not listed - easy peasy!
If you have any interest in upgrading your knife pivots, this thing is cheaper than a risky set of calipers & dead simple.
