Glock FM 78

A very capable lightweight, but durable knife for under $30. This knife holds its own against many $100+ fixed blade knives. I would recommend this to all but the most lightweight backpackers and outdoorsmen.

This is a very light but capable (and $30) knife. Be aware the low price tag has no bearing on the quality or capabilities of this knife. With a 6 1/2 inch blade it weighs only 7.8 ounces. This 6.5" spring steel blade holds an edge adequately, is tough, and easy to sharpen. I got the version without the saw back (the 78) as opposed to the 81(saw version). The sheath can attach to a belt or strap. 

At first I was skeptical about its polymer handle but my fears were put to rest by this video.

If you dont want to watch this it is essentially a grown man beating this knife till it breaks (it takes one hour and 15 minutes). The knife finally breaks when he places the blade between 2x4s and stands on the handle. A descendant of a knife-sized bayonet. The Glock knives inherit the narrow blade profile that was primarily designed for the thrust attack. However it is also effective for camp shores, digging, opening things, food preparation, and wood splitting. 

I would recommend this knife to backpackers for its light weight or any aspiring Rambos although it is to light to cut down trees it completely capable of assassinating oppressive dictators and cutting the bindings of captive missionaries.

Only downsides are when it comes it is not very sharp and the sheath is a little hard to open but can be fixed by shaving off a little of the underside of the retention clip.
