The worst thing you can hit with a saw

I managed to get about half way through a brick that was in the middle of s sycamore once

Had concrete in a limb before about 20 feet up but not from people. Termites at the base of the tree had chewed up the concrete footpath and used it to make a nest in the limb cavity. For about 6 feet along the limb was a network of tunnels all made from concrete.

I also had one. First thing I knew about it was when I blunt my saw 20ft. From there down it was entirely full of concrete, rubble, you name it. It wasn't a fun day. Fortunately I had good money on the job and didn't lose out too much. I remember I had really sore blisters on my thumb and palm of my hand from all the filing I had done.

We had a nightmare with it. Ended up cutting around and breaking it into a few big lumps with a digger. Did a fair amount of sharpening though.
