Long Skinny Dexter Spatula; What Purpose?

The carbon-steel blade is ~10" long, straight as a string. It tapers in width from 1/2" at the ferrule to ~5/16" at the radiused tip, an' in thickness from 0.070" at the ferrule to 0.025" at the tip. The grip is ~1" diameter max, 4 1/4" long; its ferrule is carbon-steel as well.
I've shown it to various folks for several years, many with enough age an' deep kitchen experience to be reliable witness to its possible purpose. Aside from the obvious acknowledgement that it is, indeed, a spatula...no person has had an answer to the question. Lots of guesses...almost all having to do with frosting distribution on a cake. I'm not convinced. Perhaps a few of you good folks can shed some accurate illumination on this wee puzzle. Thanks for lookin'!

 

Maybe for marrow ?

 

That's as good an idea as I've heard, Johnny...thanks!

 

Cake splitter? Dexter makes professional kitchen ware, so odds are this wasn't made for home use.

 

Another good suggestion...an' I hadn't considered the commercial cookery aspect. Thanks, Evely!

 

Looks more like for frosting a cake, the metal ones are better for a smooth surface.

 

It's long enough for wedding cakes if you need to smooth off the top. The bottom layers can be 16 inches (about 40cm) if not even wider.
