MNU, my Gerber is fairly recent, so I wonder if they changed the heat treat? I used my wire cutters on some pretty heavy gauge fence wire, and didn't see any signs of damage. As for the knife, I really haven't used it enough to test the edge holding, since I use other knives for most of my cutting chores. But I really like the knife compared to the one on my original Leatherman PST. Steel was WAY too soft on the Leatherman, and I never could get a decent edge on it. The Gerber, on the other hand, took a really nice edge in fairly short order, and is holding it well. Like I said, I haven't used it much, but with the Leatherman knife, the edge would just oxidize away, even without use. Plus, with the Gerebr, you can pretty much get JUST the right combo of tools, whereas most od the other multi-tools I've seen have just one basic "load" of tools that you can't change.
