Where did heck tate get the switch blade?

He got it from bob ewell. He was going to use the knife to kill the kids. Heck tate took it to cover up that boo radley killed bob ewell.

Actually he got the kitchen knife from bob ewell. He got the switch blade from someone on the street.

No, I think the first answer is right, though. You have to actually combine the context clues together to get the right answer.
