Answer:
What gets sharper the more you use it?
I am in the past never in the future. I don't exist but have existed. I saw what you saw and that is what I will ever see.
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
I get paid when I drive away my customers. What am I?
I am seen in the water. If seen in the sky I am in the rainbow a jay's feather and lapis lazuli.
A town has only two barbers. One of the barbers has a nice, tidy haircut, and the other has a shaggy, messy haircut. Which barber should you go to?
