Abstract
A downhole system and a method of performing an operation downhole. The downhole system includes a string, a downhole tool, and a release device. A downhole tool is coupled to a string via the release device. The release device includes a shear member therein having a first shear axis that has a first shear resistance and a second shear axis having a second shear resistance less than the first shear resistance, wherein the first shear axis is aligned with a longitudinal axis of the string and the second shear axis is aligned with a circumferential axis of the string. The string is conveyed through a borehole to place the downhole tool at a selected location of the borehole. The downhole tool is secured within the borehole and the string is rotated to release the release device.
