Yep, a big problem (and dangerous) in colder climates.
I have a Chinese rework station with the same "feature".
Weller stations (have?) had super flexible silicone cords.
Leo..
And the super flexible cords also have problems. Some assemblers whip the cords around to get them out of their way and one of the 3 wires in the cord eventually breaks. When my company way young, I used to disassemble the irons and shorten the cords so they would work again. After two times, the cords were too short.
The really tiny wands have the same cords, but are not fixable by shortening the cords.
The problem becomes bad when the plastic strain relief gets brittle and brakes, leaving sharp edges.
now we just order new wands.
