All the holds in this set were shaped a long time ago by Gordon Low, one of Uncarved Block's original and most prolific shapers.  The original shapes were not created in the same method as the rest of the Uncarved Block line and have their own unique feel and appearence.   These holds are in much the same style of Uncarved Block and remain very finger friendly with smooth lines.  

See these holds in action in the short video below; all holds used in the problem, both hands and feet are HD Holds.
