Spearhead

A spearhead is the sharpened tip of a spear, fitted to the shaft to create a pointed weapon designed for piercing targets. Traditionally attached via a tang or socket, it can be made from stone, bone, bronze, iron, or steel. Shapes vary by culture and era, commonly including leaf-shaped, triangular, and barbed designs.

Historically, spearheads have been among the most widespread and durable weapons across many regions, from the Stone Age onward. Stone and ceramic examples show flaked or ground edges, while metal heads are forged or cast. The design of a spearhead balances penetration, durability, and ease of attachment to the shaft, with regional variations reflecting available materials and fighting styles.

Metaphorically, the term spearhead is used to describe the leading element of a campaign, movement, or initiative. To spearhead something means to initiate and direct its development, often coordinating resources, strategy, and execution among participants.

In military usage, the phrase can also refer to the front line of an attack or to a rapid assault unit designated to breach enemy positions and lead a broader offensive. The concept emphasizes initiative, speed, and the ability to shape the course of action through proactive leadership.
