Naniwa Professional Stone Series This is Naniwa’s highest-quality sharpening stone. There are ordinary sharpening stones, and then there are stones that become your most valuable tools. The Naniwa Professional is one of those. Experienced users seek a stone that not only sharpens well but does so quickly.

With dimensions of 210 x 70 x 20 mm, this stone is nearly perfect for most knives and tools. Its thickness ensures it will last through countless sharpening sessions.

Magnesia Bonding What sets the Professional series apart is the bonding material used between the abrasive grains. Unlike the resin used in the Naniwa Superstone series, this series uses Magnesia Bonding. This results in greater density and cohesion between the abrasive particles, giving the stone the fastest sharpening ability among all
