the very first mechanical i ever tried. callled PUNCHCUTTER. it just would not penetrate. i knew riley puckett as he was developing his bloodtrailers at the time. he is actually the person who sold me the puchcutters. his wife told me that if i didnt like them(punchcutters), she would let me exchange them for another broadhead. after a boar hunt in which i got 1 inch of penetration at point blank range w/ a 70 lb golden eagle- i returned them. that biotch would not exchange them. needless to say i never purchased another item from them. he had a heart attack right after that and died. she moved the operations to west va. she remarried and named one of the models of bloodtrailers after him(austin wedgehead). heck, if i would of married her there might be a mdel named "johnny wedgehead".. LOL.
