Tree Climbing Spurs
Hooks, climbers, spurs, and irons, are all general terms for a pair of climbing spurs. "Gaff" refers to the spike of the spur only. Spurs are useful in removals, especially spar work. Spur climbing damages trees, piercing their protective layers and opening pathways for disease and insects to further damage the tree. Don't use your spurs on a tree unless you're removing it.
