The invention relates to underwater sports, namely to harpoon guns for skin diving. Harpoon head includes a housing coupled coaxially with the striking portion of the tip formed in the form of a cone or many-sided pyramid with a base mating the housing to the rear of which is formed coaxially threaded, a channel response rod harpoon, affecting part of the tip is provided with a blade dagger type with double-edged grinding with width in the rear of 1,1-3 times the diameter of the tip, the blade edges of the blade are coupled with acute angles subtended sharpening faces to the tip formed in a rib conjugate at an acute angle sharpening faces the side of the blade sides are made symmetrical relative to the central blade plane, combined with a central tip axis, and The blade of the blade surface is a surface formed by the movement of the line along the blade of the blade perpendicular to the central tip axis, wherein the blade maximum width of the rear portion installed at the base of the cone or many-sided pyramid striking portion of the tip, wherein the cone or many-sided pyramid striking s portion perform the role of the ribs the blade stiffness and simultaneously role tensioner tissue target before cropping conjugate faces sharpening the blades of the blade are made at different angles to the central blade plane and parallel to each other in cross-section along opposite sides of the blade, wherein the edge tip formed at an angle to the center the blade plane and is formed by conjugate at an acute angle opposite faces sharpening blade The blade and the surface is a surface of an Archimedean screw with the direction angle of attack associated with the working direction of the housing socket thread. In front of the blade to the tip of the blade pulled at an angle of 30 ° -45 ° to the central axis of the tip. Conjugate faces sharpening the blades of the blade are made at equal angles to the central plane of the blade and parallel to each other in cross-section along oppo
