Hi;
I am solid and hard. I am very expensive today. A young fellow once cut up one of my cousins into 12" sections for some kind of tubular ships. Boy, did his DAD get mad. I am usually not used anymore . In the Fifties me and my Square and Triangular relatives, Not to mention Flatheads in the Family got used in the Tool and Die Making trade. Oh that's right, they use computers now!
So do you think you know what I am? Oh, here's a twist, I contain a Lot of Cellulose Naturally! You see many of my family every day. You also sit on me and sleep on me and if you are lucky, you share family meals upon the broad chests of my cousins. Yup, I am useful in Model building and Life .
Only an in depth answer will be the winner on this one ! ! I am only found at Lowes and Home Depot
