Oh, no particular specific use in mind. I'm just wondering about quality and durability. I have had the CS SRK since the early 1990's. The 1095, I think my USMC Ka-Bar is made out of this, and I see that the Warthog is. The Spyderco is going to be my new pocket knife, replacing the Buck Alpha I lost last Spring...

! I don't know what the Buck Alpha was made out of, but is must have been a SS, it seems to feel/look like the AUS-6 on the Spyderco. Spyderco will end up as Pocket carry for work. The Warthog Impact (1095 Carbon) I just ordered, that will ride under my car seat, so if I go hiking (on trails where I may encounter others) after work or on my lunch break (I travel quite a bit), I have a small belt knife to strap on. This knife looks small, 8 inches or so O/A length. If I run into someone on a busy trail, I dont want to scare them...LOL! If I was out in the deep woods, away from my fellow man, I would take one of my Bowies or a Hatchet. But on a trail in southern Maine I WILL run into people, and one must take steps not to upset the Granola crunchers out there...LOL!!!! So I figured the Ka-Bar Warthog with it's 3 5/8 blade is not too scary looking.
I'm just wondering out of the three (Warthog, SRK, Spyderco Endura) which had the BEST overall steel?, Ease of sharpening, edge retention, strength, etc.
