When cutting a mirror away from a surface, what cutting tool is recommended?

When cutting a mirror away from a surface, using piano wire is particularly effective because it allows for a smooth, controlled cut. Piano wire is thin and strong, making it suitable for slicing through adhesive that may be holding the mirror in place without risking damage to the glass itself. This method provides precision when removing the mirror, especially in tight or challenging spaces where larger tools might not fit comfortably.

Utilizing other tools such as a glass cutter can lead to the risk of shattering or damaging the mirror, as glass cutters are designed primarily for scoring rather than cutting through adhesive. Hacksaws and wire cutters also lack the finesse needed for this type of job and might apply too much pressure or create jagged edges, making them less ideal for safely detaching a mirror from any surface.
