An ergonomically-designed, multipurpose tool including a handle, a blade with a shank and a tip, and a fastener for attaching the handle to the shank. The blade has a curved outer edge extending substantially from the shank to the tip, with, preferably, an integrally-formed gut hook positioned near the shank and opening toward the tip. A portion of the outer edge is sharpened to form a cutting edge. The fastener is user-operable for moving the blade from a first operating position where it opposes the handle to at least one next operating position, for example, extending forward of the handle for use as a hatchet. Regardless of the position of the blade, the user can control the length and direction of a cut by pivoting the wrist alone, the forearm at the elbow, the entire arm from the hand gripping the knife to the shoulder, by pushing or pulling the knife with the hand and forearm, or any combination thereof. Range of motion, dexterity and control of the cutting edge are thereby improved, with greater comfort than is possible with a conventional knife. The handle may include a compartment for storing one or more additional instruments for use therewith, such as a saw, a serrated blade, an ice pick, a fish hook, a knife blade, a file, a wrench, and a screw driver.
