When is it strategic to strike a window with the sharp end of a tool?

Striking a window with the sharp end of a tool is strategically advantageous when faced with double or thermo-pane glass because these types of windows are constructed with two layers of glass that create an insulating air space between them. This added thickness can make it considerably more difficult to break through with blunt force; therefore, using a sharp tool increases the likelihood of penetrating the glass effectively.

This technique not only facilitates entry but also minimizes the risk of extensive collateral damage or excessive noise that might occur when using a blunt object. In situations where immediate access is crucial, such as a fire or rescue operation, this approach becomes particularly useful, as it enhances both speed and efficiency in breaking the barrier presented by these sturdier window types.
