Description: South African knifemakers André Thorburn and André van Heerden create exceptional folders. The often collaborate on knives together -- creating their A2 knives. It has been quite some time since the Andres made the A4 and it's back by popular demand! The compact, pocket friendly size makes this an A2 favorite for EDC.
The blade is perfectly centered with silky 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. Thorburn and van Heerden created this special A4 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 drop point blade is formed from N690 stainless steel, a super-steel created by Bohler in Austria. It takes an incredibly sharp edge and holds on to it. Increased toughness gives it better resistance to edge chipping. The blade is hollow ground for an easy to maintain edge.
The scales are formed from OD green G10. The machined surface of the G10 along with jimping on the thumb ramp provides a sure, comfortable grip. The gently rounded handle feels sturdy and fills the hand perfectly. The handle is completed with bronze anodized titanium liners. The ultra-light pierced titanium pocket clip is mounted for right-handed tip-up carry. The pocket friendly A4 is a knife you will want to carry!
Exceptional fit throughout.
