Robert Herder kitchen knife, walnut handle 14 cm

Traditional Solingen Windmill knife. This knife is regarded as the superior deluxe version of the renowned Lignum 3, another top-quality knife by Robert Herder. This superb kitchen knife is handcrafted by Rudolf Broch, the master knife maker. His traditional expertise and workmanship guarantee that this kitchen knife is crafted using techniques that have almost become obsolete. The blade is made of carbonic steel with a percentage of 1.1 carbon. The blade is therefore not stainless steel and must be maintained and protected with special care. This means that this knife needs to be cleaned well and dried thoroughly after each use. Its thinly ground blade has a hardness rating of 60-61 HRC. The blade is polished blue in the traditional way, which is something that is only done to top-of-the-range knives of outstanding quality. All this special treatment and processing does result in a knife that can in fact become rusty, but which is particularly sharp and which sharpens itself as it were during usage. All you have to do to ensure that your knife remains razor-sharp for life is to use a sharpening steel from time to time.
