Description: Des Horn is one of the fathers of the South African knife industry. His influence can be clearly seen in other South African's work, but also extends into knives made around the world. Whether put to a daily carry folder or an art knife, his attention to detail and skill is legendary.
The blade on this Model 450 Ultra-Light is Nitrobe 77 martensitic stainless. This powder based alloy represents a revolutionary combination of corrosion resistance and edge strength -- setting it apart from all other knife steels. Nitrogen replaces carbon as the martensite initiator in the hardening process. It is made from Rapid Solidification Powder (RSP) to reduce the sizes and quantities of unfavorable solidification structures. Finally, it undergoes a complicated triple tempering cycle including four cryogenic quenches in liquid nitrogen to give greater strength and a finer edge capability (finer grain structure) than the best high tech steels. The performance of this knife is at a totally different level!
The blade is perfectly centered and has smooth action. It is easily opened using the front flipper mechanism. This style of flipper is not designed to be flicked open, but instead is rotated with the thumb. The lock bar is grade V Titanium with a silicon nitride detent ball (Hrc 93!). The gently rounded handle feels comfortable in the hand, despite being so inobtrusive.
Exceptional fit throughout! The Model 450 is extremely light, stainless and completely WATERPROOF!
