As it seems to be strong, you probably will not break during work so much, I think that it will be hard to become "work break because the spring hook broke." It seems likely that you bought this more cheaply than folding cheap articles many times.
Previously, I purchased about half the price of this product, but the tip was damaged by several times use. This product, the material itself seems to be robust and safe. Also, although the construction is similar to that of a certain tool maker, it is easy to put power because the part of the hand is vinyl coated.
