Well, I wouldn't worry so much about scuffing the powder coat. That will occur anyway with repeated use. If you want to keep it looking factory new buy another one and leave it in the box, keeping the one you have as a user. Whenever I find a commercial blade that I really like I end up accumulating several: one NIB, one that I carry and use, and a beater that I carried and used until it became a beater.
I cannot sharpen knives well due to my disability, so I've accepted my limitations and have other folks who are really good at that sort of thing do it for me.
Now, what I'm going to say next is probably close to blasphemy here at this forum: I am going to recommend that you check out an overpriced and inferior sharpening system. Experts will tell you all sorts of reasons why you should avoid this POS, but it is easy to use and gets your knives sharp and I've used it in the past on cheap knives with factory grinds (do not use it on a custom). Thing is called a "Warthog" and they do not seem to have a website. The only place I've seen them sold is at gun shows, and occasionally one pops up on eBay. Thing consists of a frame that holds a pair of spring loaded honing rods together that give way to resistance as you pull the blade through. A brother of mine had one in his store for customer use and it worked great . . . for some things. Certain grinds will not sharpen properly with this system.
Is this the system you were talking about?

There are a number of sharpening systems available which would be called "guided", which simply means that the angle is fixed in some kind of mechanical form, and you the user are only left to concentrating on rubbing the entirety of the blade on the stone. Some of these systems are extremely simple, one-piece setups that are sort of "training wheels" for free-hand sharpening, to ones that are just meant for a cheap precise way of sharpening, on up to some of the more expensive professional setups. Here are the ones I know of:
Razor Edge Systems Angle Guide:

This is simply a clamp that you put on to the back of your knife blade which keeps it at a fixed angle while you pass it over the stone. This one uses screws, there are other versions of this style guide available.

The big disadvantage with guides of this style is that the guide itself will wear on the stone, so overtime it becomes impossible to preserve the angle you sharpened your knife at. Otherwise, it requires marking of where exactly you put your knife into the clamp/clip at in order to get the same angle each time.
Someone already posted a link to the Lansky guided-rod setup, but DMT also makes a similar product called the "Aligner" and another "Magna guide". These products work very similarly to the Lansky, and the great thing about them is that you can set your own angle. However, they also have the problem of needing to be marked in order to put them back in the clamp correctly and get the right angle.

There are some more expensive and extensive guided sharpening systems if you want to get really precise. EdgePro makes several systems, the most popular of which I would say is the Apex. There is also a system called the Wicked Edge Knife Sharpening system that some users here like.

There's also this sharpener being discussed in the Maitenanace section called the "Work Sharp Knife Sharpener" which is basically a hand-held belt grinder. It seems to do a fairly good job from what I've read.
