Secateurs

 were a type of scissors gardeners used on plants.

The Eighth Doctor stored his secateurs in the TARDIS library under "B" for Capability Brown. He wanted to use them to extricate himself from a bramble bush. (AUDIO: The Witch from the Well)

The parents of Max and Tommy Collins kept secateurs for work on their garden. (PROSE: Joyride)

Secateurs were commonly found in gardens on Earth. Jack Harkness once used a two-year-old playing near secateurs as a metaphor for humans and alien technology. (PROSE: Slow Decay)
