Welcome to the forum.
In essence, you have asked about the big misconception: there are no tools that magically enable the creation of a highly polished edge, except for the proper grit compounds. The rest is all time and technique; as a novice (even as an experienced sharpener), depending on your goals, you can easily spend 9-10 hours per knife. It's like polishing any other metal, especially jewelery.
I'm not at all clear about any dangers involved in sharpening to a mirror finish which are not involved in general sharpening.
Which version of the WorkSharp did you buy? I use a WorkSharp Ken Onion with the Blade Grinding Attachment; this gives me a little miniature belt grinder that does OK on my personal knives. The nice thing is that it will easily produce a highly polished edge - if you use the finest belts, the cloth strop, and some of the right compound.
Honestly, I'd just use that - that way, you only have to learn one sharpening system, and it pretty much does everything.
There is a place on the web which sells good compound at a good price; however, they are not forum sponsors, and I can't name them. If you want to drop me an email to find out, go ahead. I will say that the green compound is not the most effective on the "supersteels" which are so popular; essentially, the "super" in "supersteel" means vanadium, which is too hard for the green compound to actually work.
Also, a work of encouragement: many of the edges people refer to as "mirror" are not truly mirror edges. As an example, I had a Brous Blades Raven in my hands for a couple days. It was factory new; Brous advertises this blade as having a mirror finish.
Honestly, I would have been ashamed to call that finish a "mirror" and sell it as such. It's going to take a lot for me to ever own a Brous knife; if the truth about the edge is stretched so far, to my mind that means the truth about other facets of the knife will be stretched. Maybe the heat treatment isn't as good as claimed? I have no way of knowing that, except that I might end up spending a lot of time resharpening and not know why.
So, out of the gate, you will most likely have to put in a lot of time to get a true mirror finish.
I can tell you as well that I can take a knife which clearly does not have a mirror finish; it has plenty of scratches, however. If I position that blade just so, and have the light catch the blade at the angle I want, it will look pristine. Like the best mirror you have seen. That trick works well for photo shoots, and I'd bet it is used at least now and then.
Once you're ready to move away from the Work Sharp, and consider other products, I would take a look at the Wicked Edge. I find the WE to be quite intuitive, and think that it is a natural way to go.
Best of luck with your project!
