Description: South African knifemakers André Thorburn and André van Heerden create exceptional folders on their own right. When they decided to collaborate on knives together they created A2 knives.
The blade is perfectly centered and the action is silky smooth -- 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. Thorburn and van Heerden are masters of the IKBS pivot and the action on this flipper is as smooth as it gets!
The harpoon tip blade is formed from CTS-XHP stainless steel. This US-made steel is an air hardening, high carbon, high chromium, corrosion resistant alloy. The grinds are satin finished while the flats are mirror polished, showing off the crisp, clean grinds. The blade is hollow ground for an easy to maintain edge.
The scales are formed from silver strike carbon fiber. Aluminum wires travel through the carbon fiber weave. Jimping on the thumb ramp aids grip. The gently rounded handle feels sturdy and fills out the hand perfectly. This A7 is completed with blue anodized titanium liners surrounding a marbled carbon fiber backbar. The ultra-light titanium pocket clip is mounted for right-handed, tip-up carry.
Excellent work throughout!
