Donât mess with me, or Iâll
knock shock you down. Well, thatâs what this Blast knuckle is all about. This device is capable of stunning your counterpart with a massive 950,000V of power, incapacitation him for atleast five to ten minutes. Meanwhile, you can contact the police, or call your neighbor for help. It sells for $50 (approx), but check out if legal where you live. I like it!
