Question: is the course/fine India combo Stone the way to go, or does the medium stone basically do the work of both? (Ie, do I really need all three, or can the combo or medium just do it all, given how tight the grit range is from course 140 to fine 400 with medium in the middle). I did just pick up a cheap soft Arkansas to cover that next 600-800 range and figure, for learning, India(s)—>soft ark—>strop could be a winner. I ordered each India grit and am thinking I really don’t need them all. (For now, stainless kitchen knives, pocket knives, chisels). Advice appreciated. Thanks.
