These are stainless steel double sided blades, about 3.5 inches in length, with a plastic comb handle/brush - the item in total is 6.5 inches in length. This is a tool for when you need a weapon in your hand, but drawing attention to that would escalate a situation, so this is for you to protect yourself on a hidden in plain sight basis.
 
This is meant for self defense ONLY and must be kept out of reach of children, as these do not look like knives, they look like hair combs. Available in black and pink, limited supply.
