I didn't leave it on a living room coffee table or really anywhere in the open. It was my girlfriends room on a nightstand tucked into my sweatshirt. And I will certainly try to sharpen the knife (like I said it's not a skill I've honed in on just yet). If I really screw it up in the process I'll probably do a blade replacement or send it to get sharpened elsewhere. I have a sharpmaker and I can use it fairly well but I need ultra fine rods for it. And as for the relationship....it won't affect my attitude toward him or my girlfriend. He saw a knife and needed to use it so he did. It is a little to ride in my opinion to grab/use something without asking but what's done is done. I'll move on and things will be fine. Life is too short to cause any raucous over something like this!
As others have said, now that you are buying nicer knives, learning sharpening skills/techniques is a must (especially since you've already shared that you like a clean pristine edge). If you want to learn to freehand sharpen, do it. It will take time and patience. There are many here generously share their time and knowledge (like jasonb and many others).
But I still highly suggest starting out on a "system" as it will greatly speed the learning curve. Just think of it as the cost of "just one more nice knife". It's no secret here that I'm a big fan of the KME Sharp system, but if money is not an issue, the Wicked Edge does get some wicked results.
But.....lets go back to the Sharpmaker that you already have. My 450 no longer carries the factory edge, but looking at other zt's, the Medium (brown) rods that you already have will probably give a more refined edge than your factory edge, let alone the Fine rods that come standard also. But "sharpness" is the biggest issue long before "refinement". The issue you have is matching the factory grind angle. Which, by the way, is often difficult to impossible as they usually "average" a target angle from heel to tip.
The SM is really just a freehand method, but with two clever popular built-in orientation angles to assist the average joe (if and only if the user can hold the knife perfectly vertical through the entire stroke AND the knife bevel is absolutely perfect and consistent ). But any edge angle can be achieved if the operator can adjust the cant of the blade and hold it throughout the entire process.
In your case, the easiest and fastest way to clean up your edge is to follow the standard SM process by using the 30 degree side and to buff out the bevel scratches, then add a micro bevel on the 40 side. Won't be perfect (especially with chips), but may get you back to the working edge.
Sorry about being a little long winded, but the op sounds a little like myself. I like to have and use nice knives (all subjective, I know), but I'm crazy ocd about my edges. In fact probably 70% of the factory edges I receive don't make the cut and go straight to the KME for a reprofile.
Time to go to the "Maintenance, Tinkering, and Embellishment" forum and read until your eyes bleed. [emoji2]. Of course if I read into the OP's personality all wrong (not withstanding original incident), I apologize. In that case, send your blade to one of the many amazing sharpening pro's here on the forum and move on.
But if you have the blade bug as bad as many of us.....it's time to learn a new skill. Either way, buy your GF's dad a $10 knife. Then sit down with him allowing him to handle both the cheap and nice knives. He will get it, unless he just hates you for touching his daughter, then you have an entire different subset of problems.

Good luck.
