i've actually seen one in action at this little get together. i think you must have a pretty high pain threshold for it. i was eating chicken wings when i heard this swoosh, i don't think i even heard the impact since i was so shocked at the results. it broked the boy's skin in one swing, not the little trickle of blood either. kind of like a gash. he was screaming bloody murder and i instantly lost my appetite. 2 lessons learned: avoid that thing at all costs and never play with someone who never handled one before.
