Ceramic Razor Blade

This minimalist single-edge razor blade goes with you anywhere, and one day just might make all the difference.  It's manufactured from zirconia ceramic, which is extremely hard, maintains a very sharp edge, and is highly wear-resistant. It will also last up to 100 times longer than conventional steel blades.  Measuring just 25mm x 8mm, it can be hidden or packed away almost anywhere, such as being sewn into a shirt placket or tucked into the tongue of your shoe. You're only limited by your imagination. The blade can easily cut through nylon rope, plastic zip ties, and most any other non-metallic form of restraint. It's a very handy addition to any survival or emergency kit.  Make sure to pick up several so that you always have one at hand when driving, traveling, or just on a casual walk in the woods. Don't leave home without it.
