Safe Edge

From DT Online

Description

The edges of thin sheet metals can be extremely sharp and dangerous, especially when cut, so often need to be made 'safe'. The simplest way to achieve this is to fold the metal over on itself along the edge. This is known as making a Safe Edge (or Hem).

Note: Use a Mallet and not a Hammer to avoid stretching the metal as it is struck (this would cause the edge to curl and distort).
