Hey MitiKoki,
Definitely looks like "sandstorm" G10 as John said, and also not a standard offering. As the guys said, for pricing advice go for the gold membership. It will move.
Now for some totally unsolicited advice. What you have there is a hell of a knife. Will preform forever. If you're going to trade it because it's not comfortable for you, which is totally cool, trade it for another busse-kin blade in the same size range. You wont get better performance.
I have a "skinny" ASH, which is INFI, with magnum handles, curtesy of an old hog who will probably read this shortly, much appreciated D by the way, and I wouldn't hesitate if it were my only tool in a difficult situation.
Anyway, good luck dude, try beating it for a while. I found that some of the larger handle blades I thought were uncomfortable actually were fine with use because they don't slide as much. Maybe use thin gloves. My "Tankbuster" is a beast, and actually very comfortable doing small work even though it's thick, but when chopping it hurt's my hand a bit, as the thiner CG handle doesn't always sit right.
