    • Disclosed herein is an arrow for hunting. The arrow includes an arrow shaft having a predetermined length and including a nock on one end and a shaft threaded part in the other end. A plurality of feathers is positioned to be adjacent to the nock of the arrow shaft. A connector includes a connecting threaded part fastened to the shaft threaded part, a stopper, and a penetration threaded part. An arrowhead is connected to the connector in such a way as to be opposite to the connecting threaded part. A penetration rotary unit has a threaded part to be fastened to the penetration threaded part of the connector, is shorter than the penetration threaded part, and has wings. A spring is positioned between the stopper and the penetration rotary unit, and provides a restoring force to bias the penetration rotary unit toward the arrowhead.
