In conjunction with Martin Knives, Boker has developed a hollow handled survival knife worthy of bearing the Boker name – the Boker Plus Apparo. An ultrathick, 6mm 440C stainless steel blade easily withstands extreme bending tests without failing. Its hollow handle is completely waterproof so you can store essential items. The handle is wrapped with cord for a secure grip and it can also be unraveled for use in an emergency. Prominent handguard protects your fingers from slipping over the blade when in use. Includes a high-quality black leather sheath. Blade length: 7". Overall length: 12-3/8". Weight: 19.2 oz.
