I have never had a Lionsteel before, so I had a couple of questions. If the knife ever needs repair or warranty work, is there anyone in the US authorized to do so, or would it have to be sent back to Italy? I would anticipate shipping costs to Italy to be fairly expensive. Also, are they easy to communicate with should I have any problems? I was just curious about their customer service should I have any problems. Thanks in advance for your thoughts.
