Kai Combi Whetstone Set Made in Japan AP0305 (#400 & #1000)

The underside of the tray has synthetic rubber ribs, making it non-slip and allowing for stable work. It has a groove to catch the water (rinsing water) on the whetstone, so it won't make a mess in the kitchen. After use, the whetstone can be drained and dried while still set in the holder.
