Samura SCS-280/C Universal Combination Whetstone #240/#800

The Samura Kitchen Universal Sharpening Whetstone is a professional-grade tool designed for the maintenance and restoration of kitchen knives of all sizes and shapes. This dual-sided abrasive stone features a coarse grit combination of 240 and 800, making it an essential accessory for heavy-duty blade repair and edge preparation.

Advantages

This whetstone offers exceptional versatility by combining two distinct abrasive surfaces in one tool. It is specifically engineered for intensive metal removal, allowing users to effectively address significant blade damage such as chips, cracks, or nicks. By utilizing the coarse 240 grit side, you can reshape the blade geometry or adjust the thickness of a heavily worn knife, while the 800 grit side prepares the edge for final honing. The stone is designed to create a natural suspension during use, which acts as a lubricant and coolant to protect the blade from overheating during the sharpening process.

Suitable for

• Restoring the sharpening angle of dull blades
• Repairing chips, cracks, and nicks on the cutting edge
• Adjusting the blade thickness of heavily worn knives
• General maintenance of kitchen knives of any size

When it may not be suitable

This whetstone is not intended for fine polishing or finishing a razor-sharp edge, as its grit levels are strictly coarse. It is also not suitable for sharpening serrated blades, which require specialized tools to maintain their unique tooth geometry.

Key specifications

• Dual-sided abrasive surfaces
• Grit combination: 240 and 800
• Material: Japanese abrasive components
• Function: Intensive metal removal and blade repair

How to use

Before beginning the sharpening process, submerge the whetstone in water for several minutes until it is fully saturated. Place the stone on a stable, non-slip surface. Use the 240 grit side for initial heavy repairs or to remove significant nicks. Maintain a consistent angle while drawing the blade across the stone. As you work, the stone will naturally release a suspension that serves as a lubricant; do not rinse this off during the process. Once the desired geometry is restored, you may use the 800 grit side to refine the edge further.

What to consider before purchase

• Ensure you have a stable base or holder for the stone during use
• Verify that your knives are not serrated, as this stone is designed for straight edges
• Consider that this is a coarse stone meant for repair rather than final finishing

Usage recommendations: Always keep the stone well-hydrated during the sharpening process to ensure the suspension acts as an effective lubricant and coolant, preventing damage to the knife steel.
