Armstrong-Blum Marvel #5 Solid Steel Rod Shear Cutter. Cuts solid steel 1/8", 3/16", 1/4" 5/16" and 3/8". We purchased new several years ago and mainly cut 5/16" galvanized steel rods with it. Has some wear but still works as it should. Always kept in climate controlled building so not rusty. We added an extension to the pipe for more leverage making it easier to cut the rods.
