3-Blade Lockback Knife features Leymar™ handle, honed blade, saw blade, half-serrated blade with gut hook, and sheath. A Lockback knife is built for safety. Opening the blade on a Lockback knife causes the "rocker" to lock against the blade, locking it open for ultimate security. Locking systems are essential for folding knives because they prevent the knife from closing on your hand during use. Measures 4-3/4" closed, 8-1/4" open. Limited lifetime warranty.
