LongBeachGary,
I had heard previously that the Leaders were indeed fragile. The tubing seems almost airily ("eerily?") thin when you tap it or simply hold it.
However in this incident which involved center punching through a 6-inch thick fallen cedar tree, I have come to the conclusion that they are tougher than they appear.
'Steel's Real' is more than a slogan.
