I use tools on a small scale (Dremel set, pliers. wire cutters, files), mostly for making jewelry. I'm pretty good with knitting needles, too. I keep a Leatherman multi-purpose tool in my purse. It's come in handy many times.
As for house maintenance, I can change lightbulbs, unblock a toilet, and hang pictures and curtains. Everything else is done by my husband. He's got a wood shop in the garage. I'm afraid to touch that equipment even when it's turned off.
