A set of floor panels provided with a mechanical locking system, wherein:
- a first edge of a first panel comprises a displacement groove and a flexible tongue in the displacement groove;
- and
- a second edge of a second panel comprises a tongue groove,
- wherein the flexible tongue is configured to cooperate with the tongue groove for vertically locking the first edge and the second edge,
- wherein a protrusion of the second panel is configured to displace and bend a tongue section of the flexible tongue into a cavity of the displacement groove during locking,
- wherein the cavity extends to an outermost edge of the displacement groove, the cavity has a first extension from the outermost edge of the displacement groove to an innermost surface of the displacement groove, another portion of the displacement groove has a second extension from the outermost edge of the displacement groove to an innermost surface of the displacement groove, and the first extension is greater than the second extension, and
- wherein the flexible tongue is essentially straight.
