It really doesn't matter if it is a lightweight knife for $0.95, a single edged razor blade, a Becker BK-9 Bowie, a Derma-Safe Knife or a SOG Jungle Primitive.
Folder or fixed blade, it is only important when it gets right down to what you need the knife to do for you in the field.
As Mike said, "...depends on what you're using it for ..."
I've hiked 100 miles in a two week stretch when a pair of scissors would have been all that I really needed.
That being said my EDC habit is to always have at least two "blades" with me. One is a decent sized folder and the other is the blade on a "small" multi-tool.
That little folder with the carabiner clip that you purchased would have served me well for everything that I needed a knife for on my two week hike. ;-)
I've long been looking for the perfect knife that does everything that anyone would ever need a knife for and IT DOES NOT EXIST!
That being said, I keep on looking and I keep on buying them. L O L
Had I been with you in Frys I would have spent the 95 cents.
It has a lot of advantages. It is inexpensive, light, easily stored within reach and I assume sharp enough to do what you need it to do.
It won't clear brush on a bushwacking expedition but it looks good to me.
