I just got back from a trip to japan whilst at cutlery tsubaya i made a last minute/rushed decision to by my first stones. I am very new to knife sharpening so i understand its not too crucial what i use to learn at this stage. Does anyone have experience/advice or criticisms of these? Do i have to soak before use? Etc NANIWA - Kagayaki Professional Series #1000 & #3000 Shapton ceramic #120 I mainly bought the #120 to finish/set bevel on knives i make myself.
