The Cold Steel 12DCST Safe Maker II Push Dagger Knife Satin Plain Edge. The Safe Maker II offers outstanding versatility, especially as a boot knife or back up. Its light weight and with overall length of six inches make it the perfect combination of medium size and big performance. The double edged design of the Safe Maker® II means you can safely "choke up" on the blade for extra fine work, while the false edge provides superior point strength. With only one sharp edge, the Safe Maker® II can double as a rescue knife.
