The Gerber Obsidian knife has 3.13 inch 440 stainless steel fine edge drop point blade. We knew what you would end up with when you put multi-tools 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 knifetool. Dual thumb studs allow it to be opened with one hand, and a safety lock ensures it stays in the position you need.
