Glittering points that downward thrust. Sparkling spears that never rust. What am I?
I plow and plow but never sow.
I can bring tears to your eyes, resurrect the dead, make you smile, and reverse time. I form in an instant, but I last a lifetime. What am I?
Face with a tree skin like the sea. A great beast I am. Yet vermin frightens me.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
