In real life you could chop, pry and bash a fence, shed or deck into pieces. Common enough use, I imagine. You could probably cut through the roof of a car to extract somebody if the doors were smashed in. I suppose it might come up. But I've never in my life needed to put something in a vice and beat it to death with a sledge hammer. Not in the back yard. Not camping. Not even when Odin bade me bring bagels to the Fire Giants. They can take a great deal of hard use and even abuse. I think you would have to try to break one. I mean really try. I'm not worried about the strength of my big WWII. Or even the strength of my little siru.
