What do you get when you combine the talents of noted knife designer Joel Pirela, the skills of master knife maker Walter Brend and Spyderco’s state-of-the-art production capabilities? You get the Brend/Pirela Mamba Folding Knife. This is one of the advanced factory folding knives. Its gracefully upswept CPM-S30V stainless steel plain edge blade faithfully replicates Brend’s legendary custom grind lines and showcases them with a contrasting two-toned finish of black titanium carbonitride (Tic) coating on the bevels and a satin finish on the flats. Special ball bearing washers in the pivot provide a butter-smooth action and allow lightning-fast openings with the blade’s integral flipper or its Trademark Round Hole. The unique flipper design offers exceptional opening leverage and serves double duty as a rock-solid hand guard in the open position. An impressive synthesis of style and ergonomics, the knife’s handle is built on a foundation of thick, skeletonized titanium liners that also form the basis of its stout liner lock mechanism. The liners are flanked by meticulously machined solid twill carbon fiber scales that are both visually striking and add additional strength to the knife’s structure. To ensure convenient carry and quick access, the Brend/Pirela Mamba includes a contoured, custom-designed pocket clip that supports right-side, tip-up carry. Overall length measures 9.25″ with a closed length of 5.48″ and a blade length of 3.77″.
