Even bought a leather belt for my Kalamazoo 1x42 The Shapton pro 2k is a great touchup stone for all kinds of knives. It is very dish resistant a true S&G. Whatever works for your progression. My quality knives use gesshin soakers. Talking about the chosera 400 versatility, another stone like that on the higher end is the gesshin 4K. It an be used as a stand alone on well trained knives.
