In addition to tree topping, another harmful practice that is considered malpractice by the International Society of Arboricultre (ISA) and the Tree Care Industry Association (TCIA) is the act of using climbing spikes/gaffs to prune trees.

I only prune trees using advanced spike-less climbing methods that leave your tree completely unharmed when I am done.

Climbing spikes should only be reserved for tree removals as they penetrate through the bark, phloem, cambium, and outer sapwood of the tree - leaving your tree open and vulnerable to disease and fungal decay - which can eventually kill the tree.

This is what happens when a tree is pruned using the old fashioned spiking climbing method:
