Description: South African knifemakers André Thorburn and André van Heerden create exceptional folders. When they work together, they create A2 knives.
The A10 Front Flipper is inspired by the iconic Thiers design from France. It is a design that the Andres have been working on and refining for over a year. This front flipper is elegantly simple, yet extremely comfortable and functional. It is among the easiest front flippers to use that I've ever tried.
The blade is perfectly centered with silky-smooth, drop-shut action -- easily opened with one hand using the discreet and ambidextrous front flipper toggle. It runs on an IKBS (Ikoma Korth Bearing System) pivot. This mechanism, which was originally designed to fit balisong knives, uses ball bearings to create exceptional action with no blade play. Thorburn and van Heerden created this special A10 Front Flipper with ceramic ball bearings. Generally IKBS bearings are made either from tool steel or from stainless steel. Stainless steel can wear away, resulting in uneven action over time. Tool steel bearings can oxidize making the action rough. Ceramic bearings are the best of all worlds. Extremely hard and wear resistant, they are also inert and will not oxidize. The inobtrusive front flipper tab is easy to use and won't get caught on things in the pocket.
The 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 Purple Haze FatCarbon. Jimping on the thumb ramp aids grip. The gently rounded handle feels sturdy and fills your hand perfectly. Anodized titanium liners surround a carbon fiber backbar. The custom external pivot is zirconium, surrounded by a matching zirconium pivot collar. The 3D machined zirconium pocket clip is mounted for tip-up, right-side carry.
Exceptional work throughout!
