Need fixed blade help

[Diamond Cut II]

Thought I'd try this in here since I didn't get much info in the other forum .

Hi, all. I'm looking for a fixed blade that I can use for utility purposes and diving(very very rarely). I've narrowed it down to three knives. The Spyderco Temperance, SWKW Rat Tail and SOG SEAL Pup. Here are the pros and cons I have found with each:

Spyderco Temperance
pros: Fully flat ground blade, VG-10 steel, optional black blade for extra corrosion resistance(which is the one I plan to get), Spyderco
cons: Partial tang( I think, someone correct me if I'm wrong), not sure if the tip is thin or not

SWKW Rat Tail
pros: Tough steel, good warranty, good corrosion resistance(?)
cons: Doesn't come with a sheath, getting a kydex sheath will add to the cost

SOG SEAL Pup
pros: Coated for corrosion resistance, dive knife, self-draining sheath
cons: Not really sheeple friendly, steel is soft when compared to the above knives

Since I plan to use this more as a utility knife than a diver, I'd rather go with the Spyderco and the SWKW. These are already too expensive for me and will be the only knife I will get so it will have to last me 'til I'm able to afford another. Thanks for all your time!

EDIT: I'm also considering the Becker Necker. How easy will it rust if I stay in salt water for about 30 min or so? Thanks again.

The SOG isn't bad, a friend of mine has one and used it quite often when we were in Korea together. It won't hold an edge as well as the other two but it won't corrode as easily either. If you ever plan to take it into salt water carbon steel just won't cut it, IMO.

For a divers knife I would look for one made out of H1 alloy like the Benchmade 100H20. It is softer than some stainless, but at least the edge won't corrode off.
