A slip for use in the anchoring of a downhole tool in the well casing is provided. The anchors include a plurality of buttons and at least one wicker. The slip is positioned about a mandrel and radially expands upon the application of force. The buttons and wicker first engage the casing in response to a first force, and the wicker deformably engages the casing in response to a second force. The second force causes the wicker to cut into and deform the casing, thereby anchoring the downhole tool for high-pressure operations.
