I work for a company that supports military applications. A colleague once told me, "If you think about, the whole reason our company exists is to help our military kill our enemies more efficiently."
My sense as an engineer is that engineering and design decisions matter. Some designs are more "efficient" for their stated purpose than others. Horse for courses, as the old saying goes.
This said, it's an interesting question and interesting that the OP posted in both the general and traditional forums. People should check out hte responses in the traditional forum for some nice cross-polinization of ideas.
My post in the traditional forum follows...
My sense is that "tactical" and "traditional" have a significant overlap.
My personal (certainly not legal) definition of a tactical knife has the following design characteristics:
- Folding so it can be easily hidden
- Locking blade to allow for stabbing
- Blade length in the 3.5" range - enough to be likely to cause significant internal organ damage
IMO, a knife becomes very tactical when you add the features:
- Finger guard to protect the hand when stabbing
- Double edge
- Fast or near instant deployment
The Spanish Navaja certainly fits my (personal) definition of a tatical traditional knife. It was widely outlawed for this reason.

The Buck 110 was widely used by soldiers in the Vietnam war era and by biker gangs in that time (and to this day).

My understanding is that the Buck 112 Ranger has it's name in "honor" of the aircraft carrier USS Ranger. My understanding (could be urban/internet myth) was that the Ranger was in port in San Diego and a fight broke out in which a sailor was stabbed with a Buck 110. The ship's commander issued an order limiting blade length of utility knives to 3" and Buck responded with the Ranger.
All this said.... I think modern tactical folders are playing a dangerous game of brinkmanship, particular with "flippers". IMO (emphasize, my opinion, it may not be yours) is that there is no functional need for automatic, assisted, gravity or detent driven flippers. IMO, these are just different technical designs to solve the same basic design goal of near instant deployment. These designs are
not about one hand opening. You can one hand open Opinels and Buck 110s, no problem. This is about
fast one hand deployment and really, the only purpose I can think of that that serves is a tactical need.
My concern with flippers and the like is that they'll cause enough of a social backlash that all locking folders get restricted where I live. Switchblades, gravity knives and automatic out the front knives already are and I would have to think that it's a possibility that flippers and the like could end up in the same bucket. That wouldn't bother me but the possibility of all locking folders getting swept up in that would.
