Correct, that's why I carry a blast match rod and a small hacksaw blade. I took a blast match to the extreme one day to see where it would fail and after sparking down the rod past where the V blade wouldn't grab much anymore I split the case and I use the rod with a hacksaw blade. I love the materials they use with the rods, I don't care to much for how bulky there items are but i do like the one hand bit. I can see how easy it would be for the sparky to fail for durability but the blast match held up well for a long time before I wore it out. I would trust my life on a blast match but that was after I abused it to a failure point to see the capabilities.
