These Irwin aviation snips are nicely made and have been working well for my needs. I use them for trimming and notching various gauges of flat sheet metal stock, duct and metal hanger strap. They also work well for trimming off recessed light frame rails for rough-ins when they are too long to fit between joists or strapping. Same thing for metal studs and device box rails. The snips are approximately 10-inches long overall will make nice smooth straight cuts for trimming edges and corners of flat stock. I can also smoothly cut back 4-inch metal duct on dryer vent and bath fan vent hoods if I unsnap the seam and lay it out semi-flat while cutting. Overall, these snips are decent and holding up to regular use so, I would buy again when needed.
