Description: South African knifemakers André Thorburn and André van Heerden create exceptional folders. When they work together, they create A2 knives.
The blade is perfectly centered with silky-smooth, drop-shut action -- easily opened with one hand using the ambidextrous flipper toggle. The blade uses IKBS (Ikoma Korth Bearing System). This mechanism, originally designed for balisong knives, uses ball bearings to deliver exceptional action with no blade play. Thorburn and van Heerden created this special A7 with ceramic ball bearings. Generally, IKBS bearings are made from either tool steel or stainless steel. Stainless steel can wear away, resulting in uneven action over time. Tool steel bearings can oxidize, causing the action to become rough. Ceramic bearings are the best of all worlds. Extremely hard and wear resistant, they are also inert and will not oxidize.
The harpoon blade is hand ground M390 stainless steel. M390 is a super-steel created by Bohler in Austria. It takes an incredibly sharp edge and holds onto it due to a high concentration of vanadium and chromium carbides. Its unique powder metallurgical process also promotes a uniform carbide distribution and clean steel properties, making M390 a popular steel used in surgical cutting instruments and in applications requiring a high finish. It offers excellent corrosion resistance due to its high concentration of chromium. The blade is hollow ground for an easy-to-maintain edge.
Handle scales are carbon fiber with presentation grade curly koa inlaid into each side. The gently rounded handle feels sturdy and fills your hand perfectly. Anodized titanium liners surround a carbon fiber backbar. The custom pivot and collar are heat colored zirconium. The matching 3D machined zirconium pocket clip is mounted for right-side, tip-up carry.
Excellent work throughout!
