When it arrived (on time) it was in a small padded envelope. I immediately thought I had ordered a toy. When I opened it, my thoughts didn't change: the thing is small. Nevertheless, I continued the installation. My last blade was 3/4" and this is 3/8". Small saw blades can make it difficult to align band saw wheels, so more care is required. After a few manual spins I was set. I had to make 3 cuts on a .250 inch 3 x 6 aluminum elbow. Each cut took 20-25 seconds, maybe less. It was like cutting a 1 x 2 strip of wood. I was surprised. I get the femurs for dogs Yes, child's play. You also get two blades. Yes, some of the black came off the bones, but I always brush the bones with a toothbrush after cutting to remove any splinters. I recommend.
