Today’s invention is two pairs of scissors in one. The frame of the scissors would be sprung apart, by default.
Different blade combinations could be slotted into the frame as desired.
Here, a set of ordinary straight blades is combined with pinking shears. Turn the scissors around and a different form of cutting tool is immediately available…no more searching for that other pair among the folds of material.
Each end of the frame might be coloured differently to ensure the correct set was about to be used at any time.
