We are ever in pursuit of a faster, easier and more effective way to sharpen kitchen knives. A tool that removes the need for the user to be particularly skilled. We think we found it! This triple stone sharpener has three different shape slots to accomodate different knives each with a specific ceramic whetstone roller to sharpen all of the knives in your ktichen. There is a slot for broad-bladed 'Deba' knives, narrow-bladed 'Yanagiba' knives and even one for stainless steel knives. 

The ceramic whetstones are mounted on a suspension roller system to ensure the entire length of the knife blade is in continuous contact with the whetstone. 

The Process:
Begin by filling the tank with water and put the lid on. Then insert the knife into the slit moving back and forth about ten times pushing to the roller lightly. Please use the optimum slits depending on the type and thickness of the knife blade. The slit closer to the handle is for single-sided blades, such as broad-bladed ‘Deba’ knives and narrow-bladed ‘Yanagiba’ knives. The middle one is for double-sided (thin) steel blades. The top one is for stainless steel knives. The large handle promises a secure grip and stable sharpening. The suspensions on the whetstone rollers make sure the rollers fit the entire blade with a constant pressure. This enables the smooth sharpening with great result.
