A log splitter is formed of a vertically arranged tube, within which a metal rod is telescopically slidably fitted. The lower end of the rod is formed as a hammer block. A pointed, wedge-like tip is secured upon the lower end of the tube and has an anvil block portion that extends upwardly into the tube. Transversely extending hand grips are provided upon the upper end of the rod for manually raising and lowering the rod to impact the hammer block against the anvil block for driving the tip into a log section. A guide maintains the axial alignment of the rod within the tube and limits the travel of the rod outwardly of the tube.
