It seams as if both of these stones have a following of there own. I have been at this str8 thing for about 2 mounths with good results. But it's getting time to touch up my razor. And would like to get into natural stones. I dont know where to start.Coticule or J-nat I know whear to buy a coticule but what is a good sit to buy a J-nat. How much do they differ from one another? I'm looking for a good stone to maintain my razor? I don't want to buy a lot of stones so witch one is more versitial? Thanks
