I sometimes fall into the category of "a knife is a knife," and that's not the greatest thing for a board like this. Yes, I know the difference in blade steels and lock strengths and so forth, but when I see people like Massad Ayoob write articles praising certain Spydercos as if they were somehow notably better than other knives on the market used for defense, I just sort of think, "Payola!" And though Spyderco's a great knife company, a knife (unlike a gun) doesn't have to be of premium quality to fill a defensive role like, say, weapon retention. It's like anything else that's hyped. I remember the movie Cliffhanger, where Michael Rooker, dangling from a precarious position with one arm, uses his other hand to retrieve his Spyderco, flip it open and insert it into the leg of his attacker overhead.
Those kind of scenes do a lot for business, just as Dirty Harry sold hundreds and hundreds of people on a huge revolver they didn't really need and couldn't handle. Yet they did want the thing. And want is what drives our economy. It's not a bad thing, but it is fascinating that your wife instantly said, "Spyderco!" when she saw the knife in the movie.
