Extracting Braum's classic skin (.skn file)

Hello,

I am well aware of the fact that this is my very first post but after 12 consecutive hours of trying I am tired to tears.

Does anyone know how to extract Braum's classic skin file (Braum_Base.skn) PROPERLY so that it can be opened and edited in a 3d renderign software like Maya or Blender? I've already used Wooxy and Skin Installer Ultimate with the same result- upon opening by the aforementioned software I always encounter an error message and fail to open the model itself. I have also tried converting it to an ".obj" using some simple tools but they produced 0 KB files all the time (probably because of the same reason).

The point is that I want to separate Braum's shield so that I can convert it later to CorelDraw, the format necessary for cutting it out of polistyrene.

I will appreciate any help and provide you with my progress making this awesome prop :)
