The only reason I'm giving it a 4 star is that after the first cut the cable threads have started gouging into the mating surface of the cutting shear surface. After about 20 cuts the grooves have gotten bigger but it is still cutting clean enough for fitting into the crimp ends. Time will tell if this will still work after 500 cuts. But I do think the shear portion could have been slightly harder. But for the price it will work.
