There is something called Blender Source Tools that you want to use:

Install that plugin and configure it like this. You find all of this in the component it adds to the Render panel.

Export Path: C:\Program Files (x86)\Steam\SteamApps\common\Blade Symphony\workshop\models\76561198025021719\YourSwordName\

Engine Path: C:\Program Files (x86)\Steam\SteamApps\common\Blade Symphony\bin
[Jester : corrected the engine path as you stated]

Game Path: C:\Program Files (x86)\Steam\SteamApps\common\Blade Symphony\workshop

QC File Path: C:\Program Files (x86)\Steam\SteamApps\common\Blade Symphony\workshop\models\76561198025021719\YourSwordName\*.qc

Obviously you need to change that number to your 64 bit steam ID (the directory should be created for you already), and change the install location if you hapen to have steam instaled somewhere else.

If you have the source SDK installed right then you can just click the button to compile the QC files.

I'll write up a Blender tutorial, and maybe even record a video, at some point. Until then just ask if you have any questions.
