The Mouse Hole is a device developed by Leopold Fitz. It uses laser-like technology to cut holes in almost any material. Fitz said he submitted it to S.H.I.E.L.D. for further testing, but it never reached distribution for some reason.
In Captain America: The Winter Soldier, Black Widow and Director Fury used this gadget to drill a hole in the floor to escape from a team of Hydra agents.
