It looks to me like something that could be used with pastry dough to make the gashes, three at a time, say in a bear claw, or cheese danish. It would be useful for combining chopped apples into dough to make apple fritters as well.
It would be a good tool for breaking up ground beef in the pan, when making something like taco meat, or browned hamburger for a sauce.
I also think it could be a good device for cutting fat into pie dough.
If all else fails, it's a throwing weapon to quickly remove an errant kitty-cat from the dining room table.
