The appearance of Dagger-axe evolved on the basis of Stone Dagger-axe. Originally a primitive hunting weapon, it was intended to be used for hunting and shooting and for war. During the Xia, Shang and Zhou dynasties, with the appearance of the bronze Dagger-axe, the jade Dagger-axe is no longer a practical weapon, but a power tool with special significance, reflecting might and symbolizing power. Because of the symbolic meaning of military power, jade Ge is often found in many noble tombs in the Shang and Zhou Dynasties, and it is a very important symbol to show the military power or military achievements of the tomb owner according to their number and size.This Dagger-axe is made of cyan Jade, partly grayish-white, with ridges on the back and two perforations, and concave grooves on the back of the blade. The lines are free and easy, the shape is solemn, and full of luxury.Only princely level in the middle and late Shang Dynasty can use. 戈的出現是在石戈的基礎上演變而來的。最初是原始狩獵的武器，本意就是用於狩獵射殺和用於戰爭的。夏商周時隨著青銅戈的出現，玉戈已不再是實用兵器，而是一種有著特殊意義的權仗器具，體現威武、象徵權力。由於玉戈具有的象徵軍權意義，在商周的許多貴族墓葬中多有發現，而且依據其數量的多少、尺寸的大小，以彰顯墓主的軍事權力或軍功大小，是一種十分重要的玉禮器。本器青玉製成，局部帶有灰白色沁色，援部起脊，上有二穿孔，刃後磨出凹形槽，線條灑脫利落，形制莊嚴，華貴十足，為商中晚期王侯級別之重器。
