The swapping washer/bearings thing was just taking an opportunity in the design I was guessing, since many others went down that path before however I had not seen it done like this in hand before. Only methods like Hinderer's tri-way, or makers like Skiff providing drop in washer alternatives.
I only found out I could swap them around because I had both their flipper and non flipper and wanted to see if I could get the washers in the flipper variant
When it comes to the collaboration side, I wasn't making the claim, Messer Depot were, as below from their website. Me personally, not at all worried how it happened, just super glad it did
Translation / local interpretation of the flipper tab name was interesting as being 'pinball'. Turns out even with this change, they say it isn't carry compliant which makes sense given how easily I can spydie flick mine
