The Pine Iron (パインアイアン Pain Aian, short for "Pineapple Iron") is the Armored Rider Arms Weapon granted either by accessing Pine Arms or via the summoning ability of Kiwami Arms. It is a flail that looks like a pineapple fruit.
Pine Iron consists of the following parts:
- Pine Conifer (パインコニファー Pain Konifā): Hard and sharp needles implanted at the tip of the iron ball portion of the Pine Iron. A needle placed at an angle so as to spread out exerts a great deal of damage as it breaks down when pierced armor or skin is pulled out.
- Quadrangle Pike (クアドラングルパイク Kuadoranguru Paiku) Spikes covering the iron ball portion of the Pine Iron. It can crush armor or hardened skin and deals great damage.
- Weight Star (ウェイトスター U~eito Sutā): The mass of alloy attached to the tip of the Pine Iron. The destructive power of the iron ball accelerated by the power of a Rider is incredible; it is said to be able to destroy the armor of a tank.
- Boost Core (ブーストコア Būsuto Koa): The silver control device that generates a magnetic field and controls the iron ball portion, installed on the bottom of the Pine Iron. In addition to accelerating the action of the generated magnetic field, it is used to correct the trajectory.
- Joint Branch (ジョイントブランチ Jointo Buranchi): The grip part of Pine Iron. It can connect with Musou Saber.
- Armored Rider Gaim
- Pine Arms (Gaim Episodes 2-4, 8, Sengoku Movie Battle, Gaim 18, 28, Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider)
- Kiwami Arms (Gaim Episodes 38, 46, Movie War Full Throttle)
- Armored Rider Ryugen (Kamen Rider Gaim Hyper Battle DVD: Fresh Orange Arms is Born!)
The Pine Iron can combine with the Musou Saber for the more effective Kusarigama Mode (鎖鎌モード Kusarigama Mōdo, lit."Chain Sickle Mode"). Like the Daidaimaru it's possible to combine it with the Hinawadaidai-DJ-Ju Taiken Mode, but it hasn't been seen in any media.
- Iron Breaker (アイアンブレイカー Aian Bureikā): After Gaim activates his Sengoku Driver's Squash function, he can execute one of four variations of this attack.
- Gaim throws/kicks the Pine Iron at the opponent, growing it if he needs it to. Once the Pine Iron is attached to the opponent's head, he strikes the target with a powerful side kick.
- Gaim launches the Pine iron to encase the target in a pine aura passes through a line of slices of pine and slams into the target with a powerful side kick. If the Pine Iron is unavailable or is already being used, Gaim just passes through the line of pine slices and kicks the target as usual.
- Gaim swings and restrains the opponent with the Pine Iron in close range, then he floats into sky, passes through the line of pine slices and kicks the target.
- It can be used without the side kick, causing the Pine Iron to become an explosive projectile instead of attaching to the target's head.
- Pine Musou Zan (パイン無双斬 Pain Musō Zan, lit. "Pineapple Unrivaled Slash"): After Gaim activates his Sengoku Driver's Au Lait function, he restrains the opponent with the Pine Iron and charges the Musou Saber with pineapple-shaped energy before slashing the enemy.
- While Kamen Rider Gaim has not been seen using Fresh Pine Arms yet, from what Fresh Orange Arms can attest, Gaim could wield two Pine Irons at once.
- If Ryugen in Pine Arms swings the Pine Iron, he can summon a golden energy projection of a Chinese dragon to attack the enemy.
