You should consider investing in a norton 4k/8k combo or a coticule. 6K isn't high enough to get a good edge. It can be done, but it's dubious at best for a newbie. For years I honed 1K - 8K, and I figured out a system that worked well for me, but for a long time I suffered with sucky edges until I figured it out.
If you insist on sticking with the 1K 6K setup, I would start heavy slurry on 1K, then water only, then heavy slurry on the 6K and dilute it down a few times (sorta like a coticule, but maybe only twice, and then polish the tar out of it with water only - AND doing so under a running stream. Then you MIGHT get a shave worthy edge...
A coticule on the other hand, once you learn how to use it, will replace that 6K immediately AND give you a finished edge.
If you got a Norton 4K/8K, you would also be set for a long time. Although I think a coti will get you an even better finish.
