The original Dog Tag Knife is designed and manufactured in the USA. It is perfect for last-ditch self-defense or survival. This knife is made of strong, ultra-light titanium alloy with a unique chisel grind edge. It is easy to resharpen, and it will only cut when pressure is applied. This knife can be safely worn around the neck with the included rubber silencer and chain. Fully engravable with medical information, owners' name, serial number, etc, just like a real dog tag.
