Today I used it for sweet summer oranges, but as soon as I lost or bent in the center, I could not complete opening and closing. There was a similar thing also in the item before purchase, which was the same, although I purchased it this time again. Recent things appear to be weak blades. I want you to use solid steel. Buy 2 pieces and spill the central part blade. How is the situation of the other person? Unfortunately we do not believe that the operation technology is bad because we have been doing for decades.
