"It's called a 'Mouse Hole'. Cuts through anything, really."
Leo Fitz[src]

The Mouse Hole is a laser-cutting device capable of cutting through almost any material. It was created by S.H.I.E.L.D. agent Leo Fitz, although it was not mass-produced and instead kept for use by high-ranking agents.



"I designed it a year ago and submitted it for testing, but it never reached distribution."
"Top agents always hog the good stuff."
Leo Fitz and John Garrett[src]

Created by Leo Fitz, the Mouse Hole never went to production for field agents, as S.H.I.E.L.D. chose to keep it exclusive for higher ranking agents.[1]
