These automatic knives are Clones of popular Italian knives and other popular brands. More will be added. Please keep in mind these are made in China and are in no way represented to be originals. We hare quite impressed with the quality. There will be some blade play and that is to be expected. If you decide to return these items you have 5 days and they must be returned in the same box as received and in the same condition, however, we feel you will be pleased. Shipping is non-refundable.
