Long hair and beards
Long hair and beards are liabilities when attacked. In a knife fight, the beard may be used to pull the chin up for a throat cut. When fighting, a long beard or long hair may be grabbed and used to gain an advantage. When on the ground, kneeling on the long hair will help keep vitims under control.
Clothing or accessories used as weapons
A belt may be used as a chain whip or a garrote. A metal pen may be used as a spike or knife. A scarf may be used for blocking, grabbing, and choking. A hot cup of hot coffee may be thrown at an attacker’s face. A purse, briefcase, laptop computer, or table may be used can be used as a weapon or shield.
Most fighting knives or other non-firearm weapons are illegal to carry, so you carry them at risk of becoming a criminal yourself. Concealed firearms are illegal except for those who have state issued permits and who are in carrying them in accordance with state law. Unless prohibited by law, almost any weapon may be openly carried but usually there are local laws that limit or control carrying them.
