[VFB] Cauteriser advice

[Reuven Segal]

Does anyone here use a cauteriser? I have been looking at some of Oliver
Edwards patterns and techniques and thought they would be fun to do.
What other things can they be used for? I have only come across one that
costs $17at an online store. I understand some
use a hot dubbing needle to do the same thing i.e. burn out dear hair and
shape legs.
Anyone got one to recommend??
Thanks,
Reuven
