The Gerber Obsidian knife has a 440 stainless steel fine edge drop point blade. We knew what you would end up with when you put multitools and knives together in the same drawer. A knife with tools on it of course! The Gerber Obsidian has a file, bottle opener, and both flat head and cross point screwdrivers thus making it a handy, ahem, knifetool. Dual thumb studs allow it to be opened single handedly and a safety lock ensures it stays in the position you need.
