PRODUCT DESCRIPTION
Opinel 24cm Natural Sharpening Stone – Lombardy Italian Whetstone for Kitchen and Pocket Knives
Discover the Opinel 24cm Natural Sharpening Stone, a traditional Italian whetstone quarried from the renowned Lombardy region near Bergamo. This natural abrasive stone has been recognized since the 15th century for outstanding sharpening qualities, thanks to its perfectly balanced and uniform composition of quartz and carbonates. Measuring 24cm (9.5 inches) long with a tapered design up to 4cm (1.5 inches) at the widest point, this water stone provides ideal length for easily sharpening Opinel kitchen knives, pocket knives, gardening tools, axes, and spades. The medium-coarse grit (approximately 320-800 range) excels at regular maintenance sharpening and edge restoration. Made in Italy and perfect for both home and outdoor use.
24cm Length – Ideal for Kitchen Knives
The generous 24cm (approximately 9.5-inch) length provides ample sharpening surface for kitchen knives, chef’s knives, and other longer blades. This size allows comfortable, controlled sharpening strokes along the entire blade length without the knife running off the stone’s edges. The extended dimensions prove particularly valuable when sharpening Opinel’s Parallèle kitchen knife collection.
Natural Lombardy Stone from Italy
Quarried from the historic stone beds near Bergamo in the Lombardy region of northern Italy, this natural whetstone comes from quarries renowned for producing exceptional sharpening stones since the 15th century. The geological conditions in this region create stone with unique abrasive properties perfect for blade sharpening. Italian craftsmen have relied on Lombardy stones for over 500 years.
Uniform Quartz and Carbonate Balance
The constant and perfectly balanced presence of quartz and carbonates in the rock provides excellent, consistent sharpening results across the entire stone surface. This uniform geological composition ensures even abrasion without harder or softer spots that create uneven edges. The natural balance creates ideal cutting action for steel removal.
Medium-Coarse Grit (320-800 Range)
This natural stone provides medium-coarse grit, generally falling in the 320-800 range depending on which part of the stone you reference. This grit level excels at regular maintenance sharpening, removing small nicks, and restoring moderately dull edges. The coarseness cuts quickly without being too aggressive for controlled sharpening.
Perfect for Regular Knife Maintenance
Ideal for regular, routine sharpening that keeps knives performing optimally between professional sharpenings. The grit level removes enough material to restore working edges without excessive steel removal. Use this stone for weekly or monthly maintenance depending on knife use frequency, keeping blades sharp without shortening their lifespan unnecessarily.
Excellent for Edge Restoration
When knives become noticeably dull from regular use, this stone restores keen edges efficiently. The medium-coarse grit removes enough material to create a fresh edge without requiring the extended time coarser stones demand. For very dull or damaged blades, start with this stone before moving to finer grits for polishing.
Fast Sharpening Performance
The balanced quartz and carbonate composition ensures quick, efficient sharpening with reasonable pressure. Unlike very fine stones requiring extensive work, this stone cuts relatively quickly, restoring edges in minutes rather than lengthy sessions. The natural composition provides consistent cutting action across different steel types.
Water Stone – No Oil Required
This natural stone uses water as lubricant rather than oil, making it cleaner and more convenient. Simply wet the stone thoroughly before sharpening, and the water creates a slurry that carries away metal particles whilst providing smooth sharpening action. Water stones typically cut faster than oil stones, and cleanup involves simply rinsing with water.
Tapered Design for Versatility
Features a tapered design measuring approximately 4cm (1.5 inches) at the widest point, tapering to a narrower edge. This shape provides versatility: use the wider area for larger blades and the narrower sections for smaller knives or detail work. The taper also makes the stone comfortable to hold during use.
Two-Sided Stone
The stone features two distinct sides: a smooth sharpening surface ideal for knives, and a rougher bottom side. The rough underside provides texture for the stone to grip work surfaces, preventing slipping during sharpening. Always use the smooth, flat side for sharpening to achieve consistent results.
Suitable for All Knife Types
This versatile stone works excellently with all knife types: Opinel pocket knives from No. 6 to No. 12, kitchen knives including chef’s knives and paring knives, carving knives, fillet knives, and knives from other manufacturers. The natural stone composition suits both stainless and carbon steel blades equally well.
Perfect for Gardening Tools
The length and shape make this stone ideal for sharpening gardening tools like secateurs, pruning knives, and garden knives. The tapered design accommodates various tool shapes whilst the length handles longer cutting edges. Keep your garden tools sharp for cleaner cuts that promote plant health.
Excellent for Axes and Spades
The robust construction and shape suit sharpening larger tools like axes, hatchets, and spades. The stone’s length accommodates curved axe edges whilst the thickness withstands the pressure required for these heavier tools. Restore sharp edges to outdoor and workshop tools using the same stone as your kitchen knives.
20-Degree Sharpening Angle Recommended
For optimal results, maintain approximately a 20-degree angle between the stone and blade during sharpening. This angle suits most kitchen and pocket knives, creating edges that balance sharpness with durability. The moderate angle proves easier for beginners to maintain consistently than steeper or shallower angles.
Portable and Lightweight
Despite its generous size, the stone remains relatively lightweight and portable at approximately 11.3 ounces (320 grams). The compact dimensions make it easy to store in kitchen drawers or take camping, hiking, or to outdoor events. Maintain sharp knives anywhere without bulky sharpening equipment.
Traditional Sharpening Method
This natural stone represents traditional sharpening methods used for centuries before synthetic stones. Many knife enthusiasts prefer natural stones for their feedback and feel during sharpening. The traditional approach connects users to knife-sharpening heritage whilst delivering excellent practical results.
Recognized Quality Since 15th Century
Lombardy sharpening stones have been recognized since the 1400s for guaranteeing excellent sharpening thanks to their geological composition. This 500+ year heritage demonstrates the proven effectiveness of these natural stones. Generations of craftsmen, chefs, and knife users have relied on Lombardy stones for maintaining sharp edges.
Made in Italy
Quarried and finished in Italy, maintaining the traditional methods and quality standards that made Lombardy stones famous. Italian craftsmanship ensures consistent quality whilst supporting traditional industries. The stone’s Italian origin guarantees authenticity from the historic quarry region.
Perfect Companion for Opinel Knives
Specially recommended for maintaining Opinel knives, this stone suits both the folding pocket knives and kitchen knife collections. The French knife maker trusts Italian Lombardy stone for their customers’ sharpening needs. Keep your Opinel investment performing optimally with the manufacturer’s recommended sharpening stone.
Durable and Long-Lasting
Natural stone construction ensures decades of reliable service with proper care. Unlike synthetic stones that wear down relatively quickly, natural stones often outlast multiple generations of knives. The substantial thickness provides ample material for years of regular sharpening before noticeable wear.
Care and Maintenance
Rinse the stone thoroughly after each use to remove metal particles and slurry. Allow to dry completely before storage to prevent damage from freezing or mineral buildup. Store in a dry location away from extreme temperatures. Never use the rough bottom side for sharpening – it’s designed only to grip work surfaces. The stone requires no oiling or special treatment beyond rinsing and drying.
