Today's PAD Challenge from Poetic Asides relies upon titling the poem with the name of a tool.  Here's my attempt at this prompt:

Heidegger’s Hammer

The carpenter swings his arm

Slamming its metal into the nail

Our tools are our bodily extensions

Engaging in the world

Ready-to-hand

Until they break

And we become aware of them

As they are present-at-hand

Beckoning us to question their

Essentiality to our projects
