Cut the curds
From Cookipedia
The curds can be cut with a commercial cutter or with a long knife. Make vertical cuts at the specified width and then repeat at 90 degrees so you have a chess-board pattern. Then make equal sized cuts at 45 degrees to cut the long square blocks into cubes.
Cutting the curds (cheesemaking)
Cheddar cheese
The curd is cut into 0.63 cm to 1.59 cm (1/4 to 5/8 inch) cubes. A smaller cube size means the cheese will be lower moisture whereas a larger cube size will result in a high moisture cheese.
It is important that cutting time is minimised and that the cuts be clean.
