Folding knife Boker Plus The Escort with 8,9cm blade. The ball-bearing, satin-finished straight-back blade made of Nitro-V is always ready for action, asserting its sovereign right of enforcement by activating the flipper. The blade is constantly protected by the reliable framelock, while pronounced jimpings on the thumb ramp and the gently curved silhouette of the grey stainless-steel handle ensure an exceptional feel and a high level of safety at work.
