Well, if price is not an issue...
Here are some knives to consider:

Just click on the thumbnail to see the larger image of:
A 5" drop point hunter made of 3/16" Talonite (r), full exposed tang, linen Micarta scales. The ideal 'desert island' knife, as it will absolutely, positively not corrode, and Talonite (r) will hold an edge a VERY long time.
Next, the ATAK2; full size Advanced Tactical Assault Knife with serrations. 7" blade, and like the rest of these Mad Dogs, composite handle, 1/4" thick 01 Starret steel, hard chrome finish. Even Mike Turber couldn't break one of these!
Next, the Mako; a drop point hunter with a 6" blade.
The K2K knife is below the Mako; this is also a 6" blade, but with the profile of the ATAK series.
Below the Mako, the pATAK2 and pATAK, or the pATAK with and without serrations. These are 5" blades, and very handy. I find it difficult, even with a high ride scabbard, to wear a knife longer than a pATAK, as the tip tends to dig into the seat. The pATAK2 is my daily carry. The serrations make it possible to go through light sheet metal or seat belt fabric, and it is sturdy enough to be able to pry a jammed auto door with.
At right is a Rob Simonich Talonite Cetan; this small knife is perfect for a back up knife, and can actually handle most of your daily cutting chores. Remember that the best knife in the world will not do you any good if you left it behind you as it was too bulky, uncomfortable, heavy, etc.
Hope this helps, Walt
