Sly 2: Band of ThievesEdit
Jean Bison, with his abilities as a lumberjack, was able to use them to great effect in Canada to "tame the wild North." Since the talons could cut through steel, they drove through even the hardest of trees like a knife through butter. In a recon job that Sly Cooper pulled off, he overheard Jean Bison talking to himself, saying that to entice his workers to tame the wilderness faster, he'd put the Clockwerk Talons as first prize in their annual Lumberjack Games.
The Cooper Gang competed in the Lumberjack Games to win the Clockwerk Talons off of Jean Bison. They cheated, but Jean Bison figured it out and knocked them all out by throwing his staff at them. After they escaped, they learn that they were inside of an old sawmill. When Bentley escaped, he found Jean Bison in the sawmill. He called Bentley "stew-pid," and revealed to him that he and his men ransacked their hideout, stole all of the Clockwerk parts and sold them to Arpeggio, including the talons.
