This tool is good value. Unfortunately I would rather pay for a higher quality tool like this. I was dismayed at the edge quality of the reamer blades. They were roughly chopped and then crushed. To hide tool marks, the inside of the grooves have been blackened. I was surprised by the jagged edges, but when I sharpened the edges the blackening went away and I understood why the quality of the edges was poor. The handle also slides in and out too easily during use, so I had to heat the end of the handle. Hardness removal tool, drill, tap and insert a set screw to prevent the handle from slipping off. Labor cost $50 for a $15 tool. I think General might change their manufacturing process for this tool.
