I would have separated his head from his torso...I cannot even begin to tell you the number of Moccasins I have dispatched in my career... Surveyors in Florida run upon these very often... My machete fixes them right up..... a snake can strike 1/3 his body length... I just use my 24" machete...(that's blade length) I have killed a rattler over 7' with a folding knife...just because I ran my mouth...I do not recommend this...
