01PUTTY KNIVES, SCRAPERS & CHISELS
Precision grinding for keen edges
A quiet companion to the kitchen counter, this Lanboshi whetstone sits ready for the ritual of maintaining your blades. Its substantial presence signals a tool built for patience and precision rather than speed.
The dual-grit surface allows you to move from repairing damaged edges to polishing them smooth. It suits chefs, woodworkers and enthusiasts who value a sharp, reliable edge on knives, chisels and gouges alike.

MATERIALS
Premium corundum construction
The stone is constructed from premium grade corundum, a material trusted by professionals in commercial kitchens and dedicated knife enthusiasts for years. This composition provides the necessary hardness to abrade metal consistently, ensuring that each pass over the stone contributes to a uniform, durable edge.
IN USE
Two stages of refinement
Begin with the 3000 grit side to repair damaged edges on blunt knives, holding the blade at an angle of ten to thirty degrees. Then switch to the 8000 grit side for ultra-fine grinding, using gentler pressure to eliminate burrs. This two-step process transforms a dull blade into one that is smoothly and keenly finished.
PRACTICALITY
Stable and easy to maintain
Soak the stone in water for five minutes before placing it on a steady platform. The included anti-slip base holder keeps the stone secure during work. After sharpening, simply wipe the surface with a wet cloth or rinse it with water, then dry it in a cool place to keep it ready for next week's session.
