The pivot point is part of the head itself so I think you need the gap to connect the head to the handle in the first place. Or no gap and hold the head in with 2 screws. Most professional brands (Snap-On, Mac, Matco) use the same gap design though. Not a professional myself, just adding to my collection lol.
That’s still no reason for there to be a gap, all the way down the shaft to the handle. That’s just a potential weakness
Do you actually use tools professionally or just collect them, btw?
If the latter, then yeah that’s pretty cool!
