Spikes

Arborist climbing irons, also known as tree climbing spurs or spikes, are specialized tools used by arborists, tree climbers, and tree surgeons to ascend and traverse trees safely and efficiently. These irons consist of metal shanks with sharp, pointed spikes or gaffs attached to the inner side. They are designed to be strapped onto the climber's boots, allowing them to grip the tree trunk or branches securely.
