Bicycle wheels and spokes.
So, I picked up a bike and nex thing you know, I've got three bikes. So I start looking into what it takes to break one down, and I decide I want to split the spokes/hub off from the rim because the rim is aluminum. Problem is, spokes are ferrous. I cut about three or four with handheld cutters before deciding I didn't want to do that anymore. I took a sawzall to a few more, that was slow. Then I found out, much to my chagrin, these things are threaded and held on with screw caps. An electric screwdriver made this way less painful, if not faster.
So, there's your tip for the day that I learned the hard way. If you're thinking "I already knew that," then you're ahead of the game. Some of us learn this stuff the hard way, and I'm envious of those who have the benefit of an easy break.
