Hi Schtik,
Krizzard's response is excellent. This knife will serve its "master" without reservation. Though any knife can has its limits, I finding the limits of this one will be difficult.
As SOG forum regulars know, part of what I oversee here at SOG is the returns department (including warranty concerns). People send back their knives for sharpening, refurbishing, fixing, or replacing--whatever might be needed for their knife. Needless to say, Ive seen a lot of knives in a lot of varying conditions.
You were wondering if anyone had put there Tigershark through hell. Any knives visiting hell get to visit SOG upon their return. In all honesty, I cannot remember a significant failure of a Tigershark (such as a significant broken tip of more than 1/2, a broken blade, or a handle failure) in the five years Ive managed Consumer Services for SOG. Ive seen some sent in for refurbishment that have been beat up like theyve seen three world wars and we give them the respectful TLC they deserve and returned them to fight another day.
Of course, this is my perspective as the one who sees more used and abused of SOGs tools than anyone else alive.
