Some use the heated pin method. But that can lead to a little more pain than necessary. Also, there is hardly any pain associated with the drill bit method except for the slight pressure you are applying.

finally, you get a satisfying eruption of crimson that, if performed soon after the injury, has a geyser effect. it's quite nice.
