How about the carbon 5-6 with sharpened top edge or teeth for versatility?

I'm partial to the Model 5. Doesn't have to be an 8", but a 6" would work just fine.

I normally like a blade 41/2-5 inches, but for this I'm thinking maybe a model 14 with saw teeth, model 18 guard, border patrol handle.

Being creative here:

Okay, for something for general utility, how about a carving set? Knife for fileting fish, cutting almost anything; fork for serving, general chores; sharpener to keep everything ready.
And for defense, just use the old Randall .45

How about a pair or trio of Model 10's? Unique handle material or each one having a different handle material.

A Battle Buddy would be cool! However, I don't believe they can be ordered with teeth anymore.

A #1, 5 or 6 inch with ST/STN grind would be cool.

Here is a late "A".

I have been looking for an excuse to try and build a #15 CDT. It's small enough to conceal, large enough to be useful in many ways.

The CDT gives some great grip configuration options, especially if it is made from a weather-resistant material like say, micarta.

I also like David's suggestion that a Randall 1911 would be a good companion if the need to bug out occurs.

Teeth no longer doable on a #CC, then how about a #15 with Teeth.
