`  == Boar Bristle ==  Excuse my ignorance of all things boar, I did a google image search of ``boar bristle`` and came up with endless pages of human hair brushes. There were 3 pictures of wild boars. Are boar bristles simply the hair of a boar, or are boar bristles somehow different from normal boar hair? Are bristles in a certain place on the boar, like on the head or face? Or all over the body? Are bristles very stiff and strong like whiskers? Would it be uncomfortable to ``lay hands on`` boar bristle, maybe even drawing blood perhaps, thus giving the ceremony some significance of pain that makes it more memorable, and shows a strong commitment?   `
