Whetstones

Whetstones are essential sharpening stones used to restore and refine the edge on professional chef knives and food prep blades. This range includes dual grit stones and combination sharpening kits suited to the demands of commercial kitchens, restaurants and catering operations. Ideal for maintaining razor-sharp edges, whetstones help improve cutting accuracy, speed and safety on the line. Durable construction and carefully selected grit levels ensure consistent results service after service.

• Dual grit whetstones offering coarse and medium or fine sides for shaping and honing blades in one compact stone.
• Combination sharpening kits with multiple grit options to handle everything from dull knives to final polishing.
• Ceramic and synthetic stones designed for reliable performance with professional chef knives and specialist blades.
• Models suited to both home enthusiasts and high-volume commercial kitchens needing frequent edge maintenance.
• Compact stones that store easily in busy prep areas while providing a stable, safe sharpening surface.

How to choose the right Whetstones

• Match the grit range to your needs: use coarser grits for repairing dull or damaged blades and finer grits for honing and polishing.
• Consider stone size so it comfortably fits the longest knives in your kitchen while still suiting your available counter space.
• Choose between ceramic and synthetic stones based on how often you sharpen and the hardness of your knife steel.
• For busy restaurants and hotels, opt for dual grit or combination stones to save time and reduce the number of tools needed.
• Think about user skill level; select stones that offer stable, forgiving surfaces for staff with varying sharpening experience.

Care and maintenance

• Soak or lubricate your whetstones as recommended by the manufacturer before sharpening to prevent glazing and uneven wear.
• Clean stones after each use to remove metal filings and residue, helping maintain consistent cutting action.
• Flatten stones periodically with a lapping plate or conditioning stone to keep the surface level and safe.
• Store whetstones fully dry in a cool, ventilated area to avoid cracking, mould or structural damage.
• Avoid dropping stones or using excessive pressure, which can cause chips, uneven wear or reduced sharpening performance.
