A Peening Hammer (aka Peining Hammer) has a flat face at one end and a Cross Pein (or Peen) at the other.
Features and Uses
Peening (aka Peining) is a process of hammering metals to improve some mechanical properties (e.g. Work Hardening). The process was traditionally used by Blacksmiths to thin out the blades of Scythes, for example, prior to Honing them with an abrasive stone.
- 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.
