This is a self adjusting wire stripper, wire cutter and crimper. A quality product WITHOUT any instructions. Here is how it works. Irwin makes one that is identical- perhaps they are made by the same company. Appears to be a quality product from Taiwan. UPC 837013019244 if you need to search. I haven't used the crimper part, just the stripper and cutter. I am strictly a home handyman and not a pro but I like this product.
