Silver Spoon Edge

My wife asked me to refinish four of her silver serving spoons to give to our daughters-in-law and grand daughters for Christmas. One of the spoons has an odd edge. At first I just thought it was wear, but it is too regular. Please take a look at the picture and let me know if anyone can tell me the purpose of this edge. Thanks…Rob

To get the last of the goodies of sweet confection. Think ice cream or pudding.

I considered grapefuit, but hadn’t thought about other semisolids. Thanks…Rob

Ice cream.
Whats the pattern Rob?

Don’t know. Probably came from Mom for a Christmas long ago…Rob
