The reason I opposed the Spyderco Moran (based on appearance), is because Ireed in his original post said he was looking for a "backup weapon/tool", so I figured the most emphasis should be on the knife's suitablity to use as a weapon. IMO this means a knife with a very secure grip, and ideally, double guard for hand protection and forward stabing leverage (an advantage of double guards often overlooked).
Of course, double guards are almost impossible to find on small knives. Some of the small daggers have them, and the New Model Blackjack Trailguide III has a good double guard. When I was looking for the same sort of knife as Ireed, I chose the Trailguide III. However, it has a blade of around 4 1/2 inches, which may be larger than Ireed had in mind.
The only other small (non-dagger) knife with a double guard I have ever seen is a Swedish boy scout knife, which has a four inch blade, stamped double guard, and smallish handle.
That leaves knives with single guards and/or pronounced finger grooves, which the Emerson knife has.
