I'm actually a fan of the package opener as well. For years I've been using: a sharpened Wenger can opener, pruning blade on the models that have it, orange peeler on the executive and 58mm models; all as makeshift package openers for clamshell packages or avoiding tape gunk from boxes on the blade.
My personal 3 favorite tools on a SAK are: Scissors, cap lifter, fingernail file/cleaner. I've long held the opinion that a dedicated package opening tool would be my 4th, so I welcome the attempt at least. This one has been fairly useful in my experience thus far. Even works sufficiently as a Philips driver in a pinch.
Another thing I'm pleased with on some of the recent models (including this one) is the 93mm fingernail tool. Considering the fact that I'm almost always carrying a larger folder, the main blade on my SAK is already my secondary blade, so the extra tool is more useful to me. I need to clean my fingernails and temporarily make a jagged broken fingernail functional much more often than I need yet another blade beyond what I am already carrying.
That's why the Companion has become my go-to, especially since they recently (FINALLY) released it in red at standard pricing. I bought the initial wood-scaled release and sanded the design off, and now I'm getting the red to do scale swaps with my other 93's. It has already replaced my compact. And I DO like the corkscrew. You might not need to open a bottle of wine on the beach too often, but when the time comes to open a bottle of wine on the beach, don't you wanna be the guy that's got us covered?
I guess all of this is just a long winded way of saying, I appreciate the attempt at innovation, even if it's not always for me. I'm not sure if I'll find an excuse to "need" one of these, but I'm happy to have the option. Sure I wish it had scissors, sure I'd love screws, but perhaps this a step in that direction.
