Blackie's Blend Power Putty Bait has a deep, heavy crustacean-type odor. Have you ever had a set location where a proper lure holder was non-existent? Use power putty in those hard to lure places like a bridge abutment, inside the lip of a steel or concrete culvert, or maybe on a no-bark water slicked log jam or any number of places your liquid lure makes a fast exit on you.
