Grinding Stone / Sharpening Whetstone Dedra Owalna 230×35×13 mm K180

Dedra Owalna 230×35×13 mm K180 grinding stone is an oval-shaped sharpening whetstone designed to restore and refine metal edges. With a K180 grit, it provides medium-coarse abrasive action suitable for reshaping, deburring and removing roughness from knives, hand tools and metal parts. The compact oval form offers comfortable manual handling and allows bench mounting for more controlled abrasion and repeatable results.

Advantages

The K180 abrasive grain balances material removal and surface finish, enabling efficient reshaping and rapid burr removal without excessive metal loss. The oval profile improves access to curved or contoured edges and reduces slipping during freehand sharpening. The stone’s dimensions make it easy to handle and store while offering a working length suitable for most common blades and small tools.

Suitable for

• Sharpening kitchen and pocket knives
• Restoring edges of hand tools such as chisels and plane blades
• Deburring metal parts and removing rusted or rough surfaces
• Workshop maintenance and hobby knife care

Key specifications

• Shape: oval
• Dimensions: 230 × 35 × 13 mm
• Abrasion grade: K180 (medium-coarse grit)
• Primary use: sharpening, reshaping, deburring
• Suitable operation: manual freehand use or bench-mounted use

How to use

Use the stone on a flat, stable surface or secure it in a bench fixture for consistent angles. Clean the blade and remove any large particles before starting. Move the blade across the stone with steady, even strokes following the intended bevel angle; for curved edges, use the oval profile to maintain contact along the curve. Periodically inspect the edge and remove metal filings from the stone surface to maintain cutting efficiency. Finish with finer abrasives or a strop when a smoother, keener edge is required.

Usage recommendations

Wear appropriate hand protection when working with sharp blades. For best results, pair the K180 grinding stone with progressive finer stones or strops to achieve the desired sharpness and edge polish. Store the stone dry and clean to avoid contamination of abrasive surfaces.
