Sorry RD I didn't notice that you'd written that the most course stone you have is a 4K. I think you can hone out a tiny ding with that but it's going to take some real time. If you go for it, just be patient - it'll get there eventually but will probably not be a quick 15 minute process. Might even take a few days. Definitely use the tape so that you're not trying to cut a completely new bevel (really tough to accomplish on a 4K stone). If it starts to make you nuts just walk away from it for a few hours. If it makes you want to do bad things to the blade walk away for a few days. If you start to go stark raving mad then send out some PMs for a honemeister. There are a few guys in PA and southern NY that can do it, many more within another day's shipping time.

Good luck!
