The present invention relates to a golf putter including: a putter head which has a golf hitting surface formed on the front thereof, and has a head hitting line formed in the front/rear direction at the center of the upper portion thereof; and extension plate which is formed on the rear of the putter head, has at least two stepped portions formed in a stepped manner, and has plate hitting lines formed on the stepped portions collinearly positioned with the head hitting line; and a shaft fixed to one end of the putter head.

1 . A golf putter comprising:
 a putter head of which a front surface is provided with a golf ball putting surface and a center of an upper portion is provided with a head putting line formed in a front-rear direction;   an extension plate formed on a rear side of the putter head, having at least two stepped parts formed in a stepwise manner, and having a plate putting line formed on the stepped parts positioned to be collinear with the head putting line; and   a shaft fixed to one end of the putter head,   wherein side plate putting lines are formed at both sides of the plate putting line of the extension plate, and   the side plate putting lines are formed to be inclined so that virtual lines extending from front ends of the side plate putting lines are in contact with a front end of the head putting line,   wherein the putter head has weight mounting grooves formed in both sides of the head putting line and spaced apart from the head putting line, and   weights, which selectively adjust a weight of the putter head, are detachably mounted in the weight mounting groove,   wherein the weight mounting groove has either a triangular pyramid shape or a polygonal pyramid shape whose cross-section decreases in a downward direction and has a fixed magnet mounted at a bottom thereof, and the weight includes a weight body part, which has a triangular pyramid shape or a polygonal pyramid shape corresponding to the shape of the weight mounting groove and has a magnet mounting groove formed at a bottom thereof, a grip part formed at a top of the weight body part, and a weight magnet mounted in the magnet mounting groove of the weight body part.
