From Tardis Wiki, the free Doctor Who reference

Secateurs were a type of scissors gardeners used on plants.

The First Doctor used secateurs to prune his roses in his rose garden. (PROSE: The Five Doctors, Roses)

The Gardeners' evolution was directed to make them fit to tend to soil, which resulted in one of their hands resembling a pair of secateurs. (PROSE: The Secret in Vault 13)

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)

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)
