Pickaxe

Pickaxe

Brief description

A T-shaped hand tool used for prying, digging, and breaking hard surfaces. It typically has a head with a pointed end and a flattened end (chisel) mounted perpendicularly to the handle.

Use / Function

  • Primary use: Breaking up hard soil, rock, and concrete.
  • Secondary uses: Mining, prying out roots/stumps, agriculture (mattock), weapon.
  • Scale: Individual.

Operating principle

  • Concentrated Force: The pointed tip concentrates the swing’s energy into a tiny area, shattering hard materials.
  • Leverage: The curve of the head and the long handle allow the user to pry apart rocks or soil.
  • Momentum: The heavy head at the end of a swing builds significant kinetic energy.

How to create it

  1. Head Creation:
    • Primitive: Use a deer antler (tine serves as pick) or a sharpened hard stone lashed to a handle.
    • Metal: Forge a bar of iron/steel. Point one end and flatten the other. Punch an eye in the center for the handle.
    • Hardening: Quench and temper the tips to prevent them from curling or dulling.
  2. Handle: Shape a strong, straight piece of hardwood (hickory, ash, oak).
  3. Assembly: Slide the handle through the eye. The eye is often tapered so the head slides down from the top and gets stuck (slip-fit), meaning centrifugal force tightens it.

Materials needed

  • Essential:
    • Head: Iron/Steel (best), Bronze, or Antler/Stone (primitive).
    • Handle: Durable hardwood.
  • Tools:
    • Forge/Anvil: For metal heads.
    • Grindstone: For sharpening.
    • Knife/Rasp: For shaping the handle.

Variants and improvements

  • Mattock: Has a broad adze blade instead of a point, used for cutting roots and digging in soft soil.
  • Ice Axe: Specialized for climbing ice.
  • Miner’s Pick: Often shorter for tight spaces.

Limits and risks

  • Safety: The sharp points are dangerous to the user and others nearby. Watch your backswing.
  • Fatigue: Heavy to use; requires good technique to let gravity do the work.
  • Eye Protection: Breaking rocks sends flying chips; eyes are at risk.
