I think that the axis part of the soldering iron is tightly fitted and the small tip is floating in the air and there is no stress of the small tip and the partition balance of the central part of the 2 part is also very good.
I have used this series (ST - 76, 77 ~) for over 30 years, but I think that it is done well. It will be continued in the future (laugh). There was a long time ago, a version that can be clamped at the edge of the desk = even a solder sucker can be inserted; still used.
