The spear in heraldry is a venerable emblem of knightly service, readiness for battle, and the direct exercise of martial duty. As one of the oldest weapons of man, it represents a straightforward and focused strength, signifying a person who is prepared to stand their ground or lead a charge in defense of their sovereign and faith. Unlike the sword, which carry connotations of justice and high rank, the spear often speaks to the practical valor of the vanguard and the tactical skill of the professional soldier. In family arms, it serves as a testament to a lineage of active military service and a reputation for being the "point" of defense for their community.

Common associations for the spear include military rank, territorial guardianship, and ancestral legend. It is a recurring charge in the arms of various European knightly orders and families whose status was originally founded on being able to provide a specific number of "spears" or mounted men-at-arms to their lord. In civic heraldry, towns situated on strategic frontiers or those with a history of repelling invaders often adopt the spear to symbolize their defensive resilience. Occupational links are traditionally found among soldiers, guardsmen, and hunters, while historical cases of "canting" heraldry use the spear for surnames such as Shakespeare, Spere, or Pike, visually reinforcing the name through the weapon.

The symbolic message of a spear is refined by its posture and physical condition. A spear shown "erect" or pointing upward signifies vigilance and readiness to act, while one placed "in bend" or diagonally suggests a movement toward conflict or a mission in progress. A broken spear—a common motif in funeral and memorial heraldry—represents a life cut short in the line of duty or a final sacrifice made in battle. When several spears are bound together, the charge emphasizes collective unity and the unbreakable strength of a gathered force.
