Honestly dejay, I would suggest that you have it honed by a pro or a fellow member if one is nearby. That way you will have a shave ready reference point for future comparison.
Later, when you feel that the edge is beginning to lose a little, you can touch it up with that 12K SS. Now if you really want to dive into honing, the bevel on a factory edge is usually sound so you can start with the touch up. I'd try 10 or 15 X strokes on plain water with little or no pressure - just the weight of the razor - then strop carefully & shave test. If it seems to pull/shaves poorly, you can try the touch up again.. if it's still not up to snuff the bevel needs to be reset and, once again, you really should send it out. I know that you want to jump right in with both feet, we all do but trust me, you'll be better served by sneaking up on the shave. Baby steps!
BTW, if you do send it out to be honed, shave with it the first time without stropping. Then strop for the second shave. That way you will know if your stropping technique is good (it's easy to ruin a good edge while stropping if your technique is way off.)
