I think your analysis is way over-thought. Tactical is just a marketing term that can, depending on the knife, actually imply how it might well be used. In other words, some "tactical" knives very well might serve a soldier well on a deployment. It would be sturdy, not shiny, easy to deploy whether fixed or folding, easy to maintain. So it is not indicative of Undesirable Design Features. Some of the features of "tactical" knives can very useful...to a soldier or anybody. Now of course plenty of characteristics may not offer much. For example a 9" Tactical Bowie is frankly not going to be very useful to most soldiers if even permitted. A million of them will get snapped up by civilians.
If we agree that a "tactical" knife is one that is useful to a soldier (and I see nowhere where we do agree on that but just for the sake of argument) probably the most "tactical" of knives in this day and age will be the knife blades on Leatherman and Gerber multitools as most of those on this forum who've served on recent deployments found things like the Leatherman wave the most useful of anything they carried.
Conversely, there are a lot of what would be called tactical knives (whether their mfgrs call them that or not) are some fine knives. Busse on the expensive end, Becker on the affordable end. All very tough, handy useful and "tactical" knives.
Don't like tactical? Get a Puukko!
