That’s not how you carve a Turkey. You actually remove each side first, a boning knife works just fine, then you slice it.
I remove the Legs and Wings first then take each Breast off intact. Slice the Breast from top to bottom on the short side and lay them down in the center of the platter. Then separate the Thigh from the Drumstick place them around the sliced Breast meat then the Wings and it looks like a flattened Bird. Kinda like this but so it looks like it was pressed flat.
