Features and Uses
The claw is normally curved, and incorporates a 'V' cut-out to draw nails from timber. The claw can be used to lever up floorboards or where other places where a lever is required. Popular head weights are between 455-680g (16 to 24oz)
Note: Place scrap wood packing under the claw to protect the surface of timber or to improve the leverage when longer nails are being extracted.
- 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.
