Disposable - OpticsPlanet Exclusive OpticsPlanet Spring Assisted Folding Knife, 7.5in Overall

At first, I thought it was a fine little knife, but it completely fell apart without abuse in less than a month of regular use. I've had a lot of pocket knives at all price points, but this has been the worst so far. The pin holding the blad in place gave out, and it flops back well past 180 degrees and is generally pointless.

I got it for free, and I wish that I had spared the environment the cost of producing a knife this bad.
