I think the ergonomics of the knife are really bad. The cavity for the firesteel causes a bad form for the handle that will make the use of the blade very uncomfortable. I doubt that the whistle will be easy to use and effective.
I think youīre better off when you get the gadgets when you can afford them. Gadgets that pack a lot of features always require some compromises. This will compromise the use of every feature (thatīs why I carry a multitool and a folder).
