Which tool assists in retrieving a patch that may be lodged in a firearm's barrel?

The tool specifically designed to retrieve a patch that may be lodged in a firearm's barrel is the patch puller. This tool is equipped with hooks or a gripping mechanism that allows the user to grasp the cloth patch snugly, making it easier to pull it out without damaging the barrel. Proper use of a patch puller is essential for maintaining a muzzleloading firearm, as a lodged patch can impede the firearm's function or create safety issues.

In contrast, a bullet puller is typically used for removing a bullet that has been improperly seated in the bore rather than for patch extraction. A nipple wrench is designed for removing and tightening the nipple on a caplock firearm, and a priming tool is often used for converting powder to the pan or charge in a flintlock firearm, which does not relate to patch retrieval. Understanding the specific use of each tool is crucial for effective firearm maintenance and safe operation.
