Description: South African knifemaker André Thorburn creates an exceptional folder. The action on this folder is silky smooth -- easily opened with one hand using the 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.
The M390 stainless steel blade is meticulously hand satin finished in the grinds and mirror polished on the flats. M390 is 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.
The scales are formed by combining thin alternating layers of carbon fiber with blue G10. The combination is quite enticing -- appearing to be black carbon fiber with a shimmer of blue. This nicely complements iridescent tones in the Zirconium bolsters.
Jimping on the thumb ramp ensures a secure purchase. The flipper allows for a very smooth and fast blade deployment. The scales are rounded for comfort and the handle fills out the hand perfectly. Zirconium bolsters have been engraved by Chris Booyson. Zirconium is a new material to the knifemaking world. It is a transitional metal that is primarily mined in South Africa and Australia. Zirconium is highly resistant to corrosion. Titanium liners have been hand fileworked and differentially anodized with light blue flats and purple inside the bevels. The pierced titanium pocket clip is mounted for tip-up carry.
Exceptional fit and finish throughout.
