Unusual Royal Ruby Amberina Embssed Kitchen Fruit Knife

We're not sure how old this glass fruit knife is. We've never seen a royal ruby amberina one before, so we assume it is newer. The color is outstanding! A Fenton dealer told us this was made by Fenton for a vendor. It has a 3 flower embossed pattern on it and it has traces of amberina showing through the edges. It has not been stone ground. Usually these glass knives were used to cut fruit or cake and pie before stainless steel was invented. This has such a deep red color it must have been made for a collectors piece. No damage!
