Built with precision by South African custom knife maker Trevor Burger, the TBC Sierra is a large, sleek, titanium frame lock flipper with tactical influence and dress carry style. Features include custom Ti Connector hardware, double row ceramic bearing pivot with ceramic detent, and full titanium spacer and clip. This version comes with a hand rubbed Elmax blade, GR5 titanium handle, and gold hardware.

Brand new, direct from TBC Knives.

Blade: The modified Sheepsfoot blade has a high performance hollow grind and over 3.5 inches of razor sharp cutting edge with a handsome hand rubbed satin finish. Elmax stainless steel provides balanced performance and durability with minimal maintenance on this powerful slicer. A ceramic bearing pivot delivers smooth, snappy flipper deployment with a well dialed detent. The flipper doubles as index guard for added safety.

Handle: Blasted matte gray titanium slabs are internally milled for weight reduction forming a slim yet substantial handle. The ergonomic design is enhanced by chamfered edges for comfort with a deep index choil and jimping near the pivot. The integral frame lock comes with a hardened steel lock face for smooth operation, solid lockup and secure operation for the life of the knife. Custom gold anodized hardware, back spacer and clip add a pop of color. Ships in a zippered nylon pouch with Certificate of Authenticity.

Carries via a right hand, milled titanium pocket clip.

Bohler Elmax: Bohler Elmax is a popular choice for high-end user grade knives. Elmax is comparable to American CPM-S30V/S35VN in terms of edge retention, toughness, and sharpening with a slight improvement in corrosion resistance.
