Thanks for sharing - great video! I recently bought a Domino that I believe had the EXACT same problem. (Luckily, the retailer let me return mine.)
Very disappointing as that seems like something that would be really easy for QA to check before shipping -- and absolutely SHOULD be checked on knives as expensive as the Southard and Domino. Makes me wonder if there is a weather/humidity/temperature variable to it which causes some of the washers to swell/warp ever so slightly between the time they leave the factory and the time they get to the customer. I mean, it's hard to believe nobody tried flipping it at the factory!
If there is a higher than average instance of issues with these ball bearing washers though, it sort of makes me question whether they are worth the added complexity. I guess I haven't had a chance to handle a knife with ball bearing washers and "perfect" tolerances, but I do know that my Chokwe and Sage 3 are pretty doggone smooth without ball bearings!
And in fairness, I should also add that the bad Domino I got was the ONLY Spyderco I've purchased in 10 years or so that has had a defect serious enough to want to return it...that's a pretty amazing track record for any manufacturer.
