The saw isn't anything special really, they're usually just a pretty big Stihl or Husky with some bolt-on mods like an oversize pull handle you can use with big fire gloves and a guard that covers up part of the bar, then a carbide chain. Cut quality on metal is terrible and the cutting process is amazingly loud. It can only cut thin metal, like roofing or siding. There's a reason nobody uses them outside of rescue applications. If you want to cut metal or concrete then the abrasive disc saws are the way to go, all the big chainsaw companies make those too. The one advantage the chainsaw has is that it can cut a combination of wood and thin metal simultaneously so it's good for cutting ventilation holes in walls or roofs.
