And interesting review. I wonder what "hard use" means to the gentleman from Iowa. As far as I know. the failure of the Pivot of a folder, particularly a decent one, is exceptionally rare. G10 really is surprisingly tough stuff.
Consider that the original American Lawman had steel liners, but they found they could make it stronger (at least, as strong) by replacing the combination of g10 and steel with just (thicker?) g10. There's a video on youtube of Andrew Demko showing just how ridiculously tough the all G10 version is.
Back to the SNG, if I recall the blade is a hair thicker than 5/32nds, flat ground, whereas the Sebenza's is over a 32nd thinner at 1/8 inch, or just a hair under, and hollow ground, with a fairly fine tip. This means the blade on the SNG is pretty clearly stronger (except for the hole in it, perhaps, but I haven't seen evidence that THAT is a point of failure on the SNG). Its handle is also, arguably, grippier, and its warranty is far far more forgiving. I'm not knocking the Sebenza, I'm just saying that I really don't think it's quite a fair comparison. Perhaps an Umnumzaan would be a closer comparison, and even that... I've seen evidence that the ceramic interface between the lockbar-face and the blade tang can slip resulting in lock failure. (this was likely an isolated incident, and I'm sure CRK would've fixed it).
I'm just saying that I haven't seen many cases where the material holding the pivot in place, failed, resulting in catastrophic knife failure, when everything else on the knife remained intact, unless the user was intentionally abusing the knife, or testing its limits, in which case, all bets are off...
Just my $0.02, for what it's worth... (At today's rate of inflation, probably substantially less than face value)
P.S.
I writing this as Mr. Ankerson was writing what he posted just above. I hadn't read his post prior to posting this.
