4) Ka-Bar Becker Knife Series
There are, I believe, nine of these survival/tactical/military knives, all made of expoxy-coated 1095 CV steel, with a distinctive black handle, the brainchildren of designer Ethan Becker. Not only are they first-rate knives, not only can you get them very, very, very sharp, but they are cult objects. The only thing that gets chopped and channeled as much as a Becker is a '55 Chevy or an AR-15. People re-grind them, re-finish them, bolt on fancy aftermarket handle scales, etch them, engrave them, shove them into sheaths that cost twice and three times what the knives themselves do.
