1. On principle I believe a person should be able to buy a Light Saber (assuming they ever exst)if that's what you want.
I also believe that an auto/assisted opener is just one more moving part to break. I don't see any practical use for one and it's highly unlikely that I will ever buy one.
My question is "Is there something I'm missing?" "Is there a practical reason to pick an assisted opener over a similar knife that isn't an assisted opener?"
Say for instance a Benchmade Barrage V. A Griptilian.
What advantage does the assisted opener give me?
The question you ask comes across kinda off-kilter to me, as if this method might be considered "wrong".
The point of this is to "assist" in opening the knife one handed. As you, and others, have stated, there are more than one way to do this.
There are advantages and disadvantages to each particular method. Some will be better suited under certain circumstances, and many are well suited for a diverse set of circumstances.
And let's not forget simple preference, because that's important as well.
I can open my three bladed Old Timer with one hand...but that involves a bit of digital dexterity, a smidgen of time, and a potential compromise on safety when handling a sharp tool. I have a greater chance of cutting myself this way than opening via a normal two handed means. And certainly more so that I would with a knife designed to be opened one-handed. Plus there's a greater than zero chance I could fumble and drop it in the process.
The whole point of a folding knife in the first place is to be able to safely and conveniently carry around a bladed tool in a more compact form, in a safe condition, but which can be readily deployed for some task at hand. This, in itself, offers many advantages...but at a compromise in knife strength and durability.
Likewise, the many means of opening provide options which people can pick and choose from to best suit their needs and desires.
