You can not safe proof the world from some morons. You recognize them as the ones who reach for a set of vise-grips instead of a wrench or socket to take a stubborn nut off a bolt. Works OK the first time but chews everything up for the rest of the world for the next time. Next time the bring a larger set of vise-grips and bugger it up more. For those people, no set of tubes are built well enough to survive stupid on two feet. I have lost count on the number of tubed guns, tubed tube set and other choke devices I have on hand. They fill two large boxes of drawers to keep them straight. And I learned 40 years ago how to keep them in a gun and not have them lock up in a barrel. I own a set of vise grips, somewhere in my tool box but have not needed them in a very long time.
