The outdoor special Leatherman SIGNAL also includes a whistle combined with a fire starter. You can use the signal whistle in situations when you need to make yourself noticed, communicate with others, or draw attention to yourself. With the fire starter, you can make a fire even in tough conditions.
The separate component can be easily replaced. It is good to have a spare one in case of loss, but also because the fire starter naturally wears out with frequent use.
