Clockwerk talons

The Clockwerk talons were one of the Clockwerk parts that helped Clockwerk survive for hundreds of years. The Thievius Raccoonus recorded several accounts of Clockwerk slicing through plates of steel with his razor-sharp grasp.

History
Clockwerk replaced his organic talons with metal ones to stop himself from aging and allow himself to become immortal.

Sly 2: Band of Thieves
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 the first-place trophy 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. He decided to let the Cooper Gang win the competition, and then he threw his staff at them. The talons, which were attached to the staff, obliterated the Cooper Gang on impact, and they were left unable to collect the talons. Bison then imprisoned them in the sawmill's control center. When Bentley woke up and escaped, he was confronted by Bison. Bison 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.

After the destruction of the Hate Chip, the talons disintegrated along with all of the other parts.
