"Chef Knives To Go .com" is where I have bought most of my Japanese kitchen knives and they also sell just about any type of sharpening equipment and bench stones you would need. They also have videos on how to sharpen.I have many stones and even a KME sharpener but if I had it to do all over again,I would keep the water stones that I use the most now,Shapton Pros,they are splash and go and handle any steel you may want to sharpen.I would get the 320 grit,1000 grit and even the 2000 grit and call it a day.Well,not actually,you will need a diamond plate for lapping the stones from time to time to keep them flat.Sharpening equipment can get pretty involved.If you own knives,you need to lean how to sharpen and maintain them. Like I said,I have many stones and of different grits but now I find I usually don't go beyond 2000 grit and the Shapton Pro is as good as they come.The 320 grit will allow you to fix your edge providing you don't have some really big chips in the edge.I actually find a sort of Zen in sharpening,so much so,I don't even use my guided systems anymore.Also,Jon,from "Japanese Knife Imports",also has some great instruction videos on how the sharpen along with there stones and knives to sell.
