One piece steel hammers have no joint between head and handle, and never come loose. They are the highest cost type of hammer construction.

Hammer Safety

A lot of minor injury is caused by hammers hitting fingers. Either keep the taps gentle while fingers are in the way, or use pliers to hold the nail.

A misstrike can send a nail flying. Use safety eyewear. This is important with masonry nails, which are especially prone to missile-like behaviour, Sledge hammers can also impart huge energy to pieces of debris.

Hammers with a damaged head face tend to push nails sideways in use, increasing work times, increasing finger injuries and launching more nail missiles. Belt sand or replace them.

Hammers have hardened heads, and 2 hammers should never be struck against each other.

Loose heads can be dangerous, and should be repaired with a wedge. A flying head can cause severe injury.

  • Wood handled hammers are very prone to loosening in time
  • One piece metal hammers are immune to loose heads.
