Description: South African knifemaker André Thorburn creates an exceptional folder. The blade is perfectly centered and has incredibly smooth action -- easily opened with one hand using the discreet and ambidextrous flipper toggle. The blade uses the IKBS (Ikoma Korth Bearing System) pivot system. This mechanism, which was originally designed to fit balisong knives, 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. Andre is a master of the IKBS pivot and this is as smooth as a knife gets!
The blade is formed from M390 stainless steel, a super-steel created by Bohler in Austria. It takes an incredibly sharp edge and holds on to it due to its 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 silver strike carbon fiber that have been nicely domed and polished. This variation of lightning strike carbon fiber uses silver toned wire (rather than copper) woven through the carbon strands. Jimping on the thumb ramp provides a comfortable, secure grip. The gently rounded handle feels sturdy and fills out the hand perfectly. Engraved, anodized zirconium bolsters provide a steadfast grip that is also very beautiful. Zirconium is a transitional metal that is primarily mined in South Africa and Australia. It is highly resistant to corrosion and scratching. Titanium liners have been fileworked and differentially anodized. A black G10 backspacer helps keep the knife light, yet strong. The 3D machined titanium pocket clip with ceramic retention ball is mounted for right-handed, tip-up carry.
Excellent fit and finish throughout!
