Kai Shun whetstone combination - 1000/6000
When using a whetstone to sharpen a knife, you are reshaping its cutting edge by grinding away tiny amounts of the blade. Learning the right way to use a whetstone may take a bit of practice, but once you get the hang of it you'll be able to keep knives razor sharp.
Since you won't want to let your Shuns get too dull before sharpening, this stone is a good choice because it lets you put a keen edge on your Shun with the 1000-grit side, then polish it to perfection with the 6000-grit side.
