: South African knifemaker André Thorburn creates an exceptional folder. The blade is perfectly centered with silky-smooth, drop-shut action. The flipper opening is tremendously easy to use for quick deployment. When combined with the IKBS ball bearing system, the action is exceptional! The Ikoma Korth Bearing System (IKBS) was originally designed to fit balisong knives and uses ball bearings to create exceptional action with no blade play. This special folder is made 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. Thorburn is a master of the IKBS pivot and the action on this flipper is as smooth as a knife gets!
The blade is hand ground M390 stainless steel, a super-steel created by Bohler in Austria. M390 takes an incredibly sharp edge and holds onto it due to its high concentration of vanadium and chromium carbides. Its 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.
Handle scales are Uni-layer Copper FatCarbon. Jimping on the thumb ramp provides a comfortable, secure grip. The gently rounded handle feels sturdy and fills your hand perfectly. Heat colored zirconium bolsters provide an elegant accent. Zirconium is a transitional metal that is primarily mined in South Africa and Australia. It is resistant to corrosion and scuffing. The custom zirconium external pivot is surrounded by a zirconium pivot collar. Fileworked titanium liners are anodized and surround a black G-10 backbar. The 3D machined TiAlN titanium pocket clip with ceramic retention ball is mounted for right-side, tip-up carry.
Excellent work throughout!
