The Wand of Dislocation is a Thaumic Tinkerer research item that, by combining the abilities of a portable hole and a Wand of Equal Trade, are able to completely move a block, such as a chest or a machine, without adverse effects (such as all the items spilling out of a chest, or only getting a machine block when breaking an IC2machine without a wrench). As such, it is especially useful for moving items secretly, or early in the game (though the materials required to make the wand are not necessarily early game items).
Here's a video that explains the wand of dislocation. https://www.youtube.com/watch?v=Cev3jf600mU
