## Summary description

Kasumi Japanese sharpening stone (model 4316-uniw) is a whetstone designed for sharpening and honing cutting tools and knives. As a traditional Japanese sharpening stone, it serves to restore blade edge geometry, refine sharpness and maintain cutting performance. Suitable for kitchen knives, woodworking tools and general edge maintenance.

## Long description

The Kasumi 4316-uniw Japanese sharpening stone is a traditional whetstone intended for restoring and refining the cutting edges of knives and tools. Designed for controlled abrasion and consistent wear, this honing stone helps bring dulled blades back to a precise geometry and produces a refined edge suitable for regular cutting tasks. The stone is appropriate for kitchen knives, woodworking tools and general edge maintenance where a reliable, repeatable sharpening surface is required.
Advantages
The Kasumi whetstone delivers stable abrasive performance and a predictable cutting action that supports uniform edge restoration. Its surface allows removal of metal to re-establish bevel angles and then to refine the micro-bevel for improved cutting performance. The stone is easy to position and use on a flat work surface and is compatible with standard wet-stropping or water-based sharpening workflows. Materials and finish are selected to balance cutting speed with a fine, controllable finish.
Suitable for
 Kitchen knives of stainless or carbon steel that require edge restoration or finishing
 Woodworking chisels and plane blades in need of regrinding and honing
 General workshop and household cutting tools maintenance
Key specifications
 Type: Japanese whetstone / honing stone for wet sharpening
 Function: Restores blade geometry and refines edge sharpness
 Compatibility: Suitable for kitchen knives, woodworking tools and similar edged instruments
 Surface behaviour: Predictable abrasion with capacity for both edge setting and finishing
 Usage method: Designed for use with water as lubricant and for controlled, manual sharpening strokes
How to use
Before use, soak or wet the stone according to standard wet-stone practice until bubbles stop appearing, or keep a thin, consistent film of water on the surface during sharpening. Place the stone on a stable, flat surface or a non-slip base. Hold the blade at the desired angle and move it across the stone with even pressure, maintaining a consistent angle and stroke length. For edge formation, use coarser passes to remove material and re-establish the bevel; follow with finer, lighter strokes to polish and refine the edge. Rinse and flatten the stone periodically to maintain a true surface.
Usage recommendations
Use the Kasumi whetstone with clean water and moderate pressure. Maintain consistent sharpening angles and alternate strokes evenly between sides of the blade to avoid uneven bevels. After sharpening, wipe the blade clean and, where appropriate, apply light oil to carbon steel edges to prevent corrosion. Store the stone dry and flat to prevent warping.
