Black Panther Curved Chunker is 7.0" with 18 Teeth and Black Panther Curved 6.5", 39 Teeth Thinning Shear are the perfect pair. Note that they are not the smoothest. They are designed so every tooth cuts precisely. Given the spacing between the teeth and the width of the teeth, you will "feel" each tooth as it makes its cut. They will become smoother with use and break in.
