Well, a safety pin is a lot thinner than a sharpened stick and a lot less likely to do damage ;-)

(I've actually heard this from a number of sources, and it was mentioned in our WFR training as well; I carry safety pins and blanket pins in my pocket FAK as they have a number of uses, including creating improvised slings.)

As for the video, excellent - thanks for posting it.

Note that it provides the same answer as noted in our Sawyer Extractor discussion as well - don't use it; she says your best snakebite kit is "a set of keys" so that you can get to a hospital asap after you hike out of the wilderness.

Lots of other solid, if not novel, information in the video, and well-presented.
