The 2 inch die cutter is 3 rows across and two rows downs... So with a 4.5 x6.5 piece a fabric I can cut 6 sqs.. I too wish they had multiple 'cuts' dies like the 2 inch die.. but for small scraps this is the one I go to first.. I have the 3 size hexagon die but I cant see myself sewing those teeny tiny ones..
the 3.5 tumbler would be another choice it has 3 tumblers in a row..
the Chisel, drunkards path dies are probably less waste as they are pretty much straight edge cuts.. I think you might have false pretense with the GO, as you will never have no waste, if you place it blade edge to blade edge i have no doubt it will be short on the sides;fabric can and sometimes slide as it goes thru the cutter... and therefore you just wasted you fabric..
Take a look at their website.... however they post the die is what it is.. For example, look at the 3.5 tumbler, it will show three in one row..
