Sledge Hammers are used by Blacksmiths working in pairs where one holds the tool (e.g. Hot Punch, Fuller, Swage or Flatter) in position whilst the other, the Striker, swings the hammer to strike the blow and shape the metal.
Features and Uses
Common weights are between 4lb and 16lb and all have long handles to generate the force required to strike heavy blows. They are also used to break up Concrete and drive in stakes or fence posts for example.
- 12oz Hammers (0.45kg) are a good useful size for general work in Design and Technology.
- Larger 2lb hammers (1kg) are used for heavier work such as Blacksmithing for example.
- Smaller hammers (e.g. 4oz and 8oz) are suitable for jewellery work and model engineering applications.
- Brick Hammers between 1lb and 1.5lb weight (450g to 700g) are suitable for school use and are available also with a Scutch Comb Chisel at one end which can be used for shaping brick and masonry.
- A 2lb Lump Hammer (0.9kg) is a good useful size for general work in Design and Technology and home maintenance tasks.
- 2lb to 4lb Sledge Hammers (1-2kg) are a suitable size for general forge-work in Design and Technology since hammers heavier than 4lb would be difficult for students to use.
