This is a vintage Waterford Crystal letter opener with a stainless steel blade. I have seen this letter opener called the Lismore pattern, but Replacements calls it WTO1. This pattern began production in 1990 and is now discontinued. It is in the original store box where it was purchased, the store was called Kruckemeyer and Cohn, in Evansville, IN. The letter opener is 8 1/4" long including the blade and handle. It is in excellent condition. MBR.
