Sharpening stone Proline 30012 — single-piece bench whetstone for tool and blade sharpening

Proline 30012 is a single-piece bench whetstone for tool and blade sharpening that provides a flat abrasive surface for manual honing and edge maintenance. Designed for general-purpose use, the stone accommodates knives, chisels, plane irons and other hand tools and is supplied as a single unit per pack. The product integrates multiple abrasive grits in a compact format with a broad working area for consistent contact along the cutting edge.

Advantages

The sharpening stone features a diamond abrasive available in several grit levels to cover coarse shaping and fine honing without the need for additional stones. A large 50 x 150 mm working surface gives stable support for longer blades and reduces the need for repositioning during sharpening. An integrated base secures the stone during use, improving safety and accuracy while keeping the abrasive flat and steady.

Suitable for

• Sharpening kitchen and outdoor knives
• Honing chisels and plane irons
• Edge maintenance for woodworking hand tools
• General-purpose sharpening in home workshops and garages

Key specifications

• Abrasive type: diamond surface (multiple grits: coarse to fine)
• Working area dimensions: 50 x 150 mm
• Single-piece bench stone design
• Includes a convenient base for locking the sharpener during use
• Suitable for manual wet or dry sharpening techniques

How to use

Place the sharpening stone on a stable surface and lock it into the provided base to prevent movement. If recommended for the chosen grit, apply water or light lubrication to the stone surface. Hold the blade at the appropriate angle and move it along the full length of the working area with steady, even strokes, maintaining consistent pressure to restore and refine the edge. Progress from coarser to finer sections of the stone as required, and finish with light passes on the finest grit to polish the bevel.

Usage recommendations

Use protective gloves and keep fingers clear of the cutting edge. Clean the stone surface after use and store it dry. For best results, use coarser grit for damaged or blunt edges and finer grit for regular maintenance and polishing.
