Wasn't that the ZT-0302 brown handled version? They haven't been available for a while... bet he finds another one! I hope Ducky was at high tide - and just had indigestion. Afterall, he survived drowning as the Titanic's assistant radioman Bride in 1958's "A Night to Remember", not to mention years of being Illya Kuryakin in 'Man from UNCLE' and it's re-makes. Oddly, no one ever discusses the knives Ducky uses... and he uses them every episode!

The one hope we have for Ducky is that he renewed his contract with CBS in April! He will be on the show for the next 2 seasons. Last I checked, DiNozo and Ziva haven't finalized their contracts yet, but this is the same thing year after year. What an ending!
