Now in its fourth incarnation, nothing beats the Bosch IXO cordless screwdriver when it comes to quick DIY tasks.

Price: £39.99 | Bosch

The 3.6 volt battery is powerful enough to put screws through wood and plaster in seconds, and remove stubborn ones with ease. An LED indicator tells you how much power is left, and the lithium-ion battery charges in three to five hours.

The holster-like carry case and wall-mountable charger are also neat touches. Just make sure nobody's around if you start waving it around like a gun while bellowing, "Hasta la vista". 

The Bosch IXO is not a glamourous device… but it is an essential one.
