From my understanding/internets 'research' (to decide whether to ditch the stem on my PX-10) the main failure point was at the top of the cut in the vertical tube for the expansion slug. The end of the cut was often hard squared-off, which became a stress riser point. If the cut was rounded (or was made to be so) the risk of failure is greatly diminished. At least that's the info I came up with, and as the end of the cut in mine
is rounded I decided to keep it (but will check regularly for signs of cracking....).
