Dusting off my first sweep brush from twenty years back

I pulled my old chimney brush from a box in the garage yesterday. It was a simple, stiff thing for basic brick flues. Back then, we worked mostly by guesswork and long hours. Now, we use small cameras to see inside without all the mess. That old tool shows how the job has gotten smarter over time. In my view, these updates help us do better work for folks. It's a good reminder of how far we've come in this trade.
