LIST OF REFERENCES

Specifies the quality and dimensions of hammers of the following types, together with the dimensions of the handles where appropriate. Joiners\' (or Warrington) hammers, engineers\' ball pein hammers, engineers\' cross pein hammers, boiler scaling hammers, double-face sledge hammers, straight-peined sledge hammers, club hammers, railway track keying hammers, cross and ball pein pin hammers, welders\' chipping hammers, adze eye claw hammers, brick hammers and steel shafted claw hammers. Tests for hammers are also included.
