I have a set of Globals and 2 Tojiro knives, and I want to learn to sharpen these before I start to upgrade to a few good knives. I am just about to buy a Bester 1200 and an Atoma 140 diamond plate as well as a stone holder. I already have an 8x3 Coticule. Will this setup be enough to learn sharpening or will I need another stone, or anything else, for that matter? The Globals are less than a month old, and the Tojiros are over a year old. Never been sharpened.
