BWhy

Until an axe with a handle exists, this is the heavy tool: a sharp-edged stone the size of the hand that chops saplings, splits bone, butchers large animals and digs. It is one stone doing the work of five tools.

CYou need

  • A flattish lump of flint, chert or fine basalt, a little bigger than the hand
  • The knapping kit (02.01)

DSteps

  1. Choose a lump shaped roughly like a flat pear. A large thick flake struck from a boulder is even better.
  2. With the medium hammerstone, strike a flake off one face near the edge. Turn the stone over and use that scar as the platform for a flake off the other face. Work round the stone this way, turning it after each blow, so the edge zig-zags all the way round.
  3. Leave the wide end thick and rounded. This is where the palm pushes.
  4. Change to the antler hammer. Rub the edge, then take long thin flakes off both faces to thin the piece and bring it to a pointed pear shape.
  5. Straighten the wavy edge with light blows that clip off each high point.
  6. Finish the cutting edges with the pusher. Leave the last hand-width near the butt blunt.
  7. Hold it with the thick end in the palm and the point forward. Chop with the side edge in short blows; do not swing it like a hammer.

EIt worked if

  • It cuts through a green sapling as thick as the wrist in a few minutes.
  • The edge runs all the way round the pointed end without a break.

FWhat goes wrong

  • It snaps across the middle while thinning. The blow was too hard or the piece was held unsupported. Rest it on the padded thigh and strike lighter.
  • A thick lump is left in the middle of one face. The flakes are stopping short. Rub the edge and strike closer to it, at a flatter angle.
  • The edge crumbles in use. It was left too thin for chopping. Blunt it slightly; a chopping edge is a strong edge.

GSafety

  • Wrap the butt in a scrap of hide or a wad of grass for heavy work. A bare flint butt opens the palm.

HIn the story

Bjorn has been breaking poles between two trees for a week and hating it. Hiro hands him the first hand axe without ceremony. Bjorn turns it over for a long time, says it is the wrong shape for wood, and uses it every day until he has something better.
