Hello, I just received the production version of the HEST folder and am very pleased with it. I am still trying to figure out what the various parts in the accompanying skull tool are for. Someone earlier pointed to me that one of the eyes can be used to remove the glass breaker; what are the uses for the two 'hairs' sticking out at the top of the skull? Also, the edge along the chin -- is it meant to be a cutting tool? Thanks.
