Description: South African knifemakers André Thorburn and André van Heerden create exceptional folders at a tremendously high skill level. When they collaborate together, they make A2 knives. This A6 Middi flipper is a midsize framelock version of the standard A6! The size is a great compromise between feeling great in the hand and easy to carry in the pocket!
The blade is perfectly centered and the action is drop shut, silky smooth -- easily opened with one hand using the ambidextrous flipper toggle. The blade 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 A6 Middi 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 blade is hand ground M390 stainless steel, a super-steel created by Bohler in Austria. M390 takes an incredibly sharp edge and holds on to it due to its high concentration of vanadium and chromium carbides. The unique powdered 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.
The handle is titanium inlaid with Blackwood carbon fiber on both sides of the knife. Jimping on the thumb ramp aids grip. The low profile handle feels sturdy and will carry in the pocket exceptionally well. An internal lockbar stabilizer prevents the lock from accidental over-travel. The custom pivot is solid zirconium and features an integral titanium pivot collar. The 3D machined zirconium pocket clip is mounted for tip-up, right-side carry.
Exceptional work throughout!
