I start with T, I end with T, and I hold T within.

With teeth I grin but never bite, a flexible spine, locked up tight. My dance begins with a pull or tug, I part and join with perfect snug. I walk no path, yet run a track, once closed, I never leave a crack.

I come I various colours You can even build a house from me Just don't step on me

I have a graph, but not from math or science, You may see a familiar face, but they will sit in silence, If you return me just five cents, you might hear a song, I committed no crime, I've been framed all along!

I am used to measure and conquer, but I am not used to cut bread or make butter. You can find me in in a castle, a pencil case and a parliament .
