One tangled itself in Hermione's hair, and Ron beat it back with a pair of secateurs; Harry succeeded in trapping a couple of vines and knotting them together; a hole opened in the middle of all the tentacle-like branches.
Pruning shears, also called hand pruners (in American English), or secateurs, are a type of scissors for use on plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, farming, flower arranging, and nature conservation, where fine-scale habitat management is required.
