Ok so in order to do this click see inside and backpack the three lines of code. Then go to this game https://scratch.mit.edu/projects/285425354/editor/ and insert the three scripts in the Knife Select sprite. Once you have done this press the flag and you will have every knife. You will know this works because when you go into the knifes you will own every single knife.
