Zusammenfassung:A shear device for a well service tool which is suspended from a sandline into a producing well and which device includes a plurality of shear rods which can be interchangeably connected between coupling members at opposite ends of the shear device and an outer stabilizing sleeve disposed in sealed relation between the coupling members in such a way as to stabilize the rod and assure that tensile loads are applied directly to the shear rod. Each shear rod is weakened along a shear section intermediately of the rod, or which is offset toward the upper end of the rod in order to reduce the overall length of the rod.
