Any Cub Scout who brings a pocket knife to a campout must be able to show the Cubmaster on demand either the Whittling Chip patch earned or the card earned. The Cubmaster or Den Leader may revoke any Scout's Whittling Chip for breach of knife safety rules at any time. Such a Scout will have to re-earn their Whittling Chip.
The scout should sign and carry the Whittling Chip card whenever carrying a pocketknife.
