I have two long teeth but no mouth to speak, I move heavy loads all days of the week. What am I, that helps to stack crates to the highest peak?

In experienced hands I can join the band. Beginners beware, ear bleeds may occur.

I'm a hurried flurry, a bustling shove, A constant motion, pushed from above. I rhyme with muscle, but lack its brute force, Instead, clever tactics chart my swift course. What am I?

Flesh and bone, a mind that roams, masters of tools, yet builders of homes. From dust to dawn, stories we weave, in laughter and tears, our essence we leave.

Behind COVID's sealant for the face? You can bet on me.
