I used to use it for art projects and measure things all over the house back then. I used it throughout Jr. High and High School for my advanced art and drafting classes and various school projects. I didn't bring it with me to college, but I would use it for projects I would build when I'd go back home for the summer. I've continued to use it around the house throughout my life for various projects and measurements around the house. I've always loved the reliable straight edge, flexibility and the ability to make precision measurement in 10ths or 100ths of an inch. About a month ago, I looked into the drawer where I normally keep it and was saddened to find it missing. I was happy to discover this evening that my 13-year old daughter had been using it for projects of her own. I'm very glad to see Starrett is still in business and they're continuing to make the world's best ruler.
