Knife sharpener stones Stalgast PL32247501 — diamond and ceramic sharpening stones

Set of sharpening stones by Stalgast, model PL32247501, consisting of a diamond stone and a ceramic stone. The diamond stone is designed for efficient material removal when restoring damaged or very dull blades, while the ceramic stone is intended for fine honing and polishing the cutting edge to achieve a smooth, precise finish. The set suits both professional kitchen environments and home use, enabling regular maintenance to preserve blade performance and extend tool life.

Advantages

The combination of a diamond and a ceramic stone provides a two-stage sharpening process: rapid sharpening and material removal with the diamond stone, followed by refined honing and edge polishing with the ceramic stone. Stones are compact and easy to handle, allowing controlled sharpening angles and consistent contact with the blade. Using dedicated stones reduces the risk of uneven grinding compared with improvised methods and supports predictable results across a range of knife steels.

Suitable for

• Restoring very dull or slightly chipped kitchen knives
• Routine sharpening and edge maintenance for chef and utility knives
• Preparing blades for fine slicing tasks that require a polished edge
• Use in professional kitchens, restaurants, catering, and home kitchens

Key specifications

• Includes two sharpening stones: diamond and ceramic
• Diamond stone for efficient material removal and quick edge restoration
• Ceramic stone for fine honing and polishing the cutting edge
• Compact dimensions suitable for manual sharpening
• Designed for use with hand-held knives made of common culinary steels

How to use

Begin with the diamond stone when the blade is very dull or has minor chips: hold the blade at a consistent angle and move it across the stone with light, even strokes to restore the edge geometry. After removing material and forming a new edge, switch to the ceramic stone to refine and polish the bevel; use fewer, controlled passes on each side of the blade until the desired sharpness and smoothness are achieved. Clean the stones and the blade with water and a soft cloth after sharpening, then dry thoroughly to prevent corrosion.

Usage recommendations

Maintain consistent sharpening angles and avoid excessive pressure to preserve blade temper. Use the diamond stone only when greater material removal is required; rely on the ceramic stone for regular maintenance. Store the stones dry and protected from impacts to keep the abrasive surfaces even and effective.
