Nitrogen cooled for enhanced hardness, flexibility and corrosion resistance Featuring exquisite, Feather blade pattern for striking, stand-out beauty. Precisely tapered blade minimises surface resistance for buttery smooth cut through. Bolster provides a perfectly engineered balance and gently encourages a comfortable and proper pinch grip. Meticulously constructed, ultra-premium handle made with burl wood and blue resin. Highly impervious to heat, cold and moisture with military-grade strength and life-long durability.
