There is a huge difference (well just times it by how far out you put your hands)
Between hauling on the thing next to the root and pulling at the tips.
One hand either side of the hub and close in won't do any damage.
The further your hands are out away from the hub the more chance you have of damaging something. Also as well pulling only one side ain't to bright either.
And that goes for metal, wood and any other material that takes your fancy.
