## Long description

The KAI AP-0304 Black Grey single-sided sharpening stone provides a compact, workmanship-focused solution for maintaining blade edges. Designed for precision sharpening of kitchen knives and other cutting tools, this stone offers a stable, single working surface with a balanced grit suited to regular maintenance and edge refinement. Its black and grey finish identifies the stone visually while keeping the toolset uncluttered.
Advantages
The single-sided design concentrates abrasive material on one flat face, allowing consistent contact and simple handling during sharpening. The stone's construction supports even wear and reliable edge results without complex setup. Its size and finish make it easy to position on a countertop or sharpening base, and it is appropriate for routine upkeep of blades to extend service life and preserve cutting performance.
Suitable for
 Kitchen knives of various steels and profiles
 Small hand tools such as paring knives and utility blades
 Home sharpening tasks where a single flat abrasive surface is required
Key specifications
 Single-sided abrasive surface for controlled sharpening
 Black and grey color finish for easy visual identification
 Compact form factor suitable for countertop use
 Suitable for routine edge maintenance and refinement
How to use
Place the stone on a stable, non-slip surface or use a dedicated holder to prevent movement. If the stone requires lubrication, apply water according to the manufacturer’s instructions and allow the surface to absorb it briefly. Hold the blade at a consistent angle and move it across the single abrasive face using controlled strokes from heel to tip, maintaining steady pressure. Repeat the process on both sides of the blade until the desired sharpness is achieved, then finish with light, alternating strokes to refine the edge and remove burrs. Rinse and dry the stone after use and store it flat to preserve the working surface.
Usage recommendations
For best results, assess blade condition before sharpening and start with moderate pressure to avoid over-grinding. Use consistent angles and equal passes on each side of the blade. After sharpening, hone the edge with a leather strop or fine finishing stone to achieve a smoother, longer-lasting cutting edge.
