Fits well the professional hand and many well known knife brands. Please notice the whetstone grinds the threats away.
When the blade doesnt't feeling smooth anymore, grind the stone in slightly higher angle, as you were carving shavings off the steel.

Remember to moisten the whetstone with water before using.
