I am thinking of buying the Norton Waterstone kit that has the 220/1000 and 4k/8k and flattening stone. I have a couple of questions about this. To start I am just entering the world of straight shaving and addictions and have never honed. Will I even use the 220/1000 combo or am I just waisting money. My intent is to learn how to hone on a couple of cheapo straights I have. My other question is whether the flattening stone will work for lapping or do I need a DMT?
