MULTI AWARD WINNING BRITISH DESIGN - Signature knife block set with integrated knife sharpener provides a beautifully engineered solution to kitchen knife storage. The ABS block features a simple and functional design, organising your kitchen workspace whilst protecting knife blade edges. COMFORT AND BALANCE - Knives are made from a single piece of steel (full forged) which runs the entirety of the knife (full tang). This means each knife is perfectly balanced, while remaining lightweight for ease of use. An angled, fully forged bolster allows for full use of the cutting edge for precision control. SUPERIOR SHARPNESS AND EDGE RETENTION - Knives feature a hand applied Japanese 15° edge for superior sharpness. When tested by CATRA, Signature knives were found to be 21% sharper on the first cut, 48% sharper in use and 135% greater edge retention than the nearest competitor. The German steel is very resistant to corrosion and is easy to sharpen (Rockwell 56).
