How'd he expect to get away with that?
How many bloody burglars carry a spirit level around with them?
"Right, I'm off burgling tonight. Lets check my kit. Stripey top. Check. Swag bag. Check. Face mask. Check. Torch. Check. Crowbar. Check. Spirit level. Check"

& in answer to the original question asked....clawhammer.
Better leverage when getting the eyes out.
