The firefighters have an impressive arsenal of tools at their disposal, ranging from axes, chainsaws, and many others. Those tools tend to lose their efficienty and sharpness with time, which is why the fire station has a dedicated room for sharpening and storing them.
In the picture, Yannick can be seen sharpening a Halligan bar (named after a New York City Fire Department First Deputy Chief, Hugh Halligan, in 1948). The tool itself serves many purposes, including punching, prying, and striking, among others. In the back, a rotary saw rests on the table.
The tools are sharpened weekly, or everytime after they've been used. Besides sharpening, it is also commong to polish, oil and paint the tools if needed.
And, for all of those wondering, the sparks are indeed real!
