1) Use 0.8 mm boards if you don't need 1.6 for rigidity reasons. They are a breeze to score once with a blade on each side and then just break apart.
2) Remove the top/bottom soldermask so the substrate is base on an about 0.25 to 0.5 mm high rectangle between the sub-boards. This will make the cutting easier since the blade gets an indentation to follow - and you don't need to cut through the mask either.
