It's a US made Allen, I guess Danaher era. I can tighten the philips on the side and it helps a bit.
Maybe the Snap-On is awesome, but honestly the Carlyle is all I need, and checks all the boxes for me. 72T, small/thin head, flush quick release, locking flex head, long handle, comfort grip. It has already paid for itself this same year I bought it, and that's at the pedestrian pace of a homeowner/car maintenance hobbyist.
