We use the STM tip as the tool to manipulate the single sheet of graphene.

• A local strain engineering approach to build nanoscale graphene wrinkles has been achieved by STM tip-directed sliding
• Anisotropic residual tensile and compressive strain remains in the vicinity of the wrinkles
• Artificial kink structure could be created on the wrinkles by controlled tip contact
• Kekulé bond order appears near the kink due to the tensile stress breaking the bond symmetry
