I had someone else fixed it!
I bought several eyelets and tried to install them by myself, but I just can't make it right without the right tools. So I decided to take it to a local shoe store. As I requested, the guy put a piece of thick leather on the sheath for 10 bucks and now I can have either horizontal or vertical carry with My AS.
Here are some pictures (sorry the speed may be very slow, I would appreciate if someone can repost them for me).
