I’ll make one instead!

“All I need is a nut driver…”
The Grinch looked around.
But, since nut drivers are scarce, there was none to be found.
Did that stop the old Grinch…?
No! The Grinch simply said,
“If I can’t find a nut driver, I’ll make one instead!”
So he filed some hex rod. Then he took some scrap sheet
And he soldered it into a nut-driving heap.
