There is a mute who wants to buy a toothbrush. By imitating the action of brushing one's teeth, he successfully expresses himself to the shopkeeper and the purchase is done.
Now if there is a blind man who wishes to buy a
hammer, how should he express himself? Think about it first before
scrolling down for the answer...

kookie says: ohhhhh shuttttt...
He opens his mouth and says, "I would like to buy a hammer."
If you got this wrong - please turn off your computer and call it a day. I've got mum's shutting down right now...
