Input: Consider Input: I bought this knife December 2018 and has been great thus far. The only downside is that the clip used to attached the knife to a pocket or belt is held by 3 small screws. With time and the weight of the knife one of the screws stripped and no longer held the clip in place. I remedied this issue with a drop of gorilla glue. Now it doesnt move and holds the clip and the knife in place.

Output: 5

Input: Consider Input: Love these excellent quality and my kids love them, but wish they made a truck or car to pull them with! Also the only complaint is that because they are close when attached, when turning curves the magnets will sometimes catch each other and mess up the creation!
