I have also used a battery-powered recip saw doing storm damage work, where it's hard to tell if it is a tree mixed with a house, or a house mixed with a tree, Used a 'carbide, nail embedded, demolition blade' (all those words are important; there are so many variations) to separate building materials from tree stuff, before the chainsaws come in. I once kept a single blade going for 3 days, and lots of battery charges! Cut up to 8-inch oak limbs with it, along with studs, plywood, particle board, corrugated metal, wiring, conduit, . . . . Not a place where you would want to use your Silky Sugoi. I do have a folding Silky hand saw for trail work, which is nice when you don't want to drag out a saw, PPE, etc.
Again, different tools for different applications.
