This is another very well made tool with good material. The jagged blades are short, very strong and made from a BigCal recommended product. This is another very well made good tool. The serrated blades are short, very strong and sharp, giving you good control over the cut. The handles are the right size and their ergonomic shape makes cutting sheet metal much easier than the scissors I've used in the past. This tool has a very unique and well-placed blade lock for picture-safe security. After a few uses, I looked for others.
