01PUTTY KNIVES, SCRAPERS & CHISELS
Precision for the blade edge
A quiet ritual on the bench, this Lanboshi whetstone offers a stable platform for restoring the keenness of your favourite blades. The substantial block sits firmly, inviting a deliberate pace that transforms dull edges into sharp, reliable tools.
Constructed from premium grade corundum, it works with either water or oil to refine steel. It suits professional kitchens and home enthusiasts alike, maintaining the integrity of knives, chisels and other edged tools through consistent care.

MATERIALS
Premium corundum construction
The core of this tool is its composition, utilising premium grade corundum to deliver consistent abrasion. This material choice ensures durability over years of use, trusted by both commercial kitchens and dedicated hobbyists. The stone’s density provides a stable surface that does not degrade quickly, allowing you to maintain high standards of sharpness without frequent replacement.
IN USE
Two-stage sharpening process
Begin with the 2000 grit side to repair damaged edges, holding the knife at a 10 to 20 degree angle. Move back and forth with gentle pressure to establish a new bevel. Then transition to the 5000 grit ultra-fine side to eliminate burrs and polish the edge until it feels smooth and keen. This two-step method ensures a refined finish rather than just a basic point.
PRACTICAL DETAILS
Stable base and care
The package includes an anti-slip base holder, ensuring the stone remains steady on your workbench during operation. After use, simply wipe the surface with a wet cloth or rinse with water, then dry in a cool place. The stone measures approximately 18 x 6 x 2.7 cm, providing ample surface area for most kitchen and woodworking blades while remaining manageable for storage.
