Sharp little teeth, yet no bite from me, I shed your blocks like falling trees. Across my face you push with care, Till tiny strands are everywhere.

I leave, yet always find my way back; swift and spinning, my journey is a loop. In playful hands, I dance with the air, a wooden traveler with a memory.

I keep things equal, left and right, I'm what you need when walking a tight height. Lose me and you'll stumble or fall, find me and you'll stand up tall. What am I?

I once was tall in forest deep, Where birds would sing and squirrels leap. Now polished smooth beneath your feet, I make your home look warm and neat.

In a twist, I bring forth day from night, a glass blossom that banishes fright. Filament's whisper, a spark's delight, casting shadows to dance in my soft, warm light.
