Pretty simple. First off, create a single shadow clone! Now that you two are standing next to each other, you both create a lightning blade in opposite hands; therefore if you create it in the right hand, he'll create it in the left and vice versa.. once you've done that, connect the blades through a "chain" of lightning and run that ass across the battlefield, slicing anything that touches the chain. You two are able to go mid range from each other and still maintain the chains connection.

Description: This technique requires the user to firstly create a shadow clone. Then, each of them will activate the Lightning Cutter on opposite hands to one another. Connecting the two techniques together, forming a chain of sorts, they are then able to use the resulting beam to slice through objects with great ease.
Note: Must first have a shadow clone in the field.
