Mushroom knives are a category of special blades designed for enthusiasts who enjoy harvesting the gifts of the forest. Knives of this kind typically feature short, sickle-shaped blades for cutting mushrooms from the forest floor to leave the mycelium undisturbed, which demonstrates care for future harvests. Often, mushroom knives have brushes at the end of the handle for rough cleaning of mushrooms on-site in the forest. Mushroom knives are available as both fixed and folding blades. They may come with or without a sheath, depending on the brand supplying them.
