The CRKT MinimalX is a killer Darriel Caston design (from D Rocket Designs) that was commissioned for the crew of a SpaceX launch. There's a lot of toughness and durability built into this compact knife. The chisel blade has a complex flat grind that's perfectly made for slicing, scraping, and—in a pinch—prying. The handy flipper keeps deployment one-handed, and the frame lock provides stellar strength. A lanyard hole increases carry options, and all these features add up to an excellent EDC knife that's ideal for an on-the-job tool.
