How can I effectively remove a stuck lead from a mechanical pencil?

To effectively remove a stuck lead from a mechanical pencil, try gently tapping the pencil on a hard surface to dislodge the lead. If that doesn't work, use a small tool like a needle or a paper clip to carefully push the lead out from the tip of the pencil. Be cautious not to damage the pencil or injure yourself while attempting to remove the stuck lead.
