I’m not alive, yet hold you tight, and keep you warm all through the night.

I build no house, yet shape every trade, In workshops and battles, my purpose is made. Some cut, some measure, some tighten with care, Without me, skilled hands get nowhere.

I make deliveries no one requests, usually addressed to castle guests.

I have a hard shell but no bones inside, I am a snack where healthy fats hide. I can be a tool to tighten a screw, Also a slang term for someone acting crazy around you.

I am the main ingredient in many shirts, socks, and under garments. To grow my crop, be ready to hunt some varmints.
