There is claimed a log splitter comprising means for penetrating a log, a handle pivotally mounted for manual operation, a cam shaped sheave which is rotated by rotation of the handle, a ratchet and pawl assembly which transmits force from the handle to the sheave, a drive cable attached so that it is wound onto said sheave, and as said drive cable is wound onto the sheave it causes a sharpened edge to penetrate the log, splitting the log, and the cam shape of the sheave produces large mechanical advantage as the log is initially penetrated, and lesser mechanical advantage but greater travel distance as the penetration continues.
