Offered here is a genuine Kyoto natural whetstone known as "Kurama", supplied with its original wooden base and presentation box. Unlike modern synthetic sharpening stones, this whetstone is made from natural stone sourced in Kyoto, Japan, a region internationally renowned among knife makers, sharpeners, and collectors for its centuries-old sharpening stone tradition. The Kurama stone is particularly suitable as a finishing stone, producing a refined edge and a beautiful polished finish on small Japanese knives, petty knives, utility knives, craft knives, leather-working knives, and similar edged tools. Mounted on a traditional wooden base, the stone is ready for immediate use and also presents beautifully as a collectible item for enthusiasts of Japanese blades and sharpening tools. Because this is a natural stone, every example is unique. Minor natural imperfections, inclusions, small chips, or surface cracks may be present and are considered normal characteristics of authentic natural whetstones.
