The Boscher is an old-style harvesting knife used for turnip, cabbage, and celery. Germany also became one of the main exporters of this knife to for the Netherlands, where they used it among the colonies for harvesting sugar cane. The silhouette of this knife also influenced another Windmill design, the Grandmoulin bread knife. These knives are carbon steel and handled with a copper beech wood, hand-shaped and sanded.
Robert Herder Windmuehlen knives are hand made in Solingen Germany utilizing old hand work techniques. The fine hand ground blades are extremely light and thin and offer a great cutting feel that is not possible with chunky mechanized ground blades. There is no excess steel on the blades, and the slight convexity makes for reduced friction and sticking during cutting. Robert Herder Windmuhlenmesser have worked hard to establish an apprentice program at their workshop to preserve old techniques that nearly disappeared from Solingen.
Carbon steel requires more care to take care of but gets sharper and holds its edge longer than stainless.
