I started with a Norton 4k, 8k also. However I added a Naniwa 12K & a 1K and honed with . those for a year or so. I found out that the 4K got to feeling very gritty so I moved on and I predict you will also. For the time being they will serve you well as they did me. I would use the 4K to set the bevel if you cannot afford a 1K. That 600 is pretty course. I use a 600K on knives only
