Knives

Unless you are buying one of these to throw in your trunk after opening a package or whatever (even then i would not get one of these), i would:

Skip any Smith&Wesson, especially at that pricepoint. They are not the same Smith&Wesson that make guns etc. The brand has been aquired (well actually just using their name) by Taylor Brands, which is not really known for quality products (a typical how-to-make-as-much-money-possible-without-spending-to-much company).

Gerber has some great ones i believe (the fixed Strongarm for example), but i would skip this brand too in this pricerange.

With these options, the CRKT or Buck would be most trustworthy, but i will still recommend spending 10-20 bucks more and get something like a Spyderco Tenacious, Buck Spitfire, Civivi Baklash/Elementum/etc or anything in that range, which aren't the best, but a whole lot better then anything you suggested.
