Considering that the DS would have to be made of strofoam or some other type of lightweight material, and yet it's supposed to crush through all that armor and apostle and what not (Come on, you can't really believe the the DS is actually sharp after all those fights, the armor and pillars and crap, being as thick as it is, and Guts not being the blacksmith that Godo is and not having access to a forge to fix it. The force in which Guts swings the massive thing is what does the damage.). I seriously doubt it could be pulled off credibly. Well, I suppose they might try CGing it.
yay for parallelism!
