Trick arrows

Trick arrows are arrows with specially-made functions. As with typical arrows, they are shot with bows, but can possess a specialized, technological function, such as incendiary explosives, recording, or listening devices. Trick arrows are one of Oliver Queen's signature weapons, used on many occasions to save himself, or achieve objectives unattainable by combat alone.

Known types of trick arrows

 * Router arrow: Shot near computers to hack into them. One was used to steal money from a corrupt businessman Adam Hunt.
 * Grappling hook arrow: To grab on to ledges for swing lines and zip lines. Used in  and many other episodes. The new "Oneida Kestrel Compound Bow" has a device that allows him to pull arrow hook by an automated way, thus being able to climb on flat surfaces in a matter of seconds. He calls this the "jettisoning arrow", which "uses compressed carbon dioxide to jettison high tensile strength polymer cables", as Cisco Ramon notes in.
 * Voice recording/Listening arrow: Recording and Listening devices for recording confessions and surveillance.
 * Ensnarement arrow: After piercing a target it launches wires into the area around the target and then pulls them tight. Used to anchor dropped bags of money to the ground to prevent them from being carried off by bank robbers.
 * Flashbang arrow: A flashbang grenade in the form of an arrow. They were used to disorient drug dealers at the beginning of an attack, to distract a hostage taker, and to explode in Malcolm Merlyn's face after he caught it during his and Oliver's last duel.
 * Explosive arrow: Explosive arrows, both time-delayed and impact.

Trivia

 * It should be noted that, in the DC comics, the proliferation and eventually gimmicky use of trick arrows by the Green Arrow was the motivation behind Mike Grell's 1987 reboot "The Longbow Hunters". Grell took Oliver back to simple shafts, and the question of whether he was willing to kill, if he believed the situation merited it.
