The is the personal weapon of Kamen Rider Zi-O's DecadeArmor forms. It can also summoned by GrandZi-O.
==History==
Assuming DecadeArmor for the first time, Zi-O summoned the RideHeisaber, which he wielded alongside the Drill Crusher Crusher when in Build Form. After successively unleashing the Ex-Aid and Drive Dual Time Breaks against Another Ghost, Zi-O appropriately switched to Ghost Form. Ultimately, Zi-O performed the Ultimate Time Break which destroyed the Another Ghost Ridewatch and set Makimura free. 
Coming face-to-face with Ohma Zi-O, his incarnation in the year 2068, Sougo refused to accept his future and transformed to attack him. Assuming DecadeArmor, Zi-O unleashed, in quick succession, the Kuuga, Kiva, and Ryuki Dual Time Breaks only for Ohma Zi-O to counter his past self with the matching Rider powers he possessed, overwhelming the younger Zi-O. 
After fighting hand-to-hand in Ghost Form against Kasshine and Decade Wizard, Zi-O switched to the two-man DecadeArmor Ex-Aid Form L and R wielding the Zikan Girade and RideHeisaber respectively while Geiz assumed GhostArmor. The two Zi-Os proceeded to engage Decade, who soon retreated through the dimensional wall as he was outmanned. When Time Jackers Uhr and Ora boarded their Time Mazines to attack the Kamen Riders, Zi-O L and Geiz boarded their own Time Mazines while Zi-O R continued the fight against Kasshine. Taking their fight to the vortex, Zi-O L and Geiz soon defeated Uhr and Ora while Zi-O R performed the Ultimate Time Break to ultimately destroy Kasshine. 
Facing Another Shinobi, Zi-O assumed DecadeArmor and struck Another Shinobi with the Blade Dual Time Break. This was followed by the Ryuki Dual Time Break, only for Another Shinobi to counter and reflect Zi-O's attack back at him with a cyclone, forcing Zi-O back to his default form. 
==Design==
The RideHeisaber is composed of the following parts:
*: The blade. It is extremely sharp, and is capable of cleanly slicing a few tanks with one swing. When charging energy for a deathblow, archived data on past Kamen Riders is sent from the Ziku-Driver via the DecadeArmor.
*: The portion of the blade that displays the emblems of the previous 19 Heisei Riders (Kuuga to Build). The emblems will glow when a special attack utilising a Rider's powers is initiated. The Crest Indicator is covered with a clear translucent protective piece with the word molded on it.
*: The clock hand on the hilt. By rotating the Hand Selector, a technique based on past Kamen Riders can be selected. When a Ridewatch is slotted onto the Ridewatch Base, the Hand Selector allows the user to select multiple techniques at once, blending them into a lethal combined attack.
*: The four 'clock buttons' surrounding the Hand Selector. From the top right, clockwise, each Quartet Ryuzer is a (in order) neuro-fuzzy control device (a neuro-fuzzy system is a system that uses a learning algorithm to determine its technical limits), a learning device, an information collecting device and an action prediction device. Data from all four are used to adjust the RideHeisaber's internal setup when necessary.
*: A Ridewatch port. When a Ridewatch is inserted, the RideHeisaber's limiter is released, entering it into an overload state.
*: The trigger.
*: The handle. Information from the Ziku-Driver is sent through the DecadeArmor into the Pass Band Connector, allowing the RideHeisaber to utilise attacks based on previous Kamen Riders.
==Special Attacks==
The RideHeisaber contains a portion of all main Heisei Riders' powers, and thus, could invoke their attacks even without obtaining or using their Ridewatches:
*
**Kuuga: Zi-O creates an energy crest of Kuuga, which is thrusted at the opponent.
**Ryuki: Zi-O coats the blade in orange flames before shooting an orange fireball at the enemy.
**Blade: Zi-O coats the blade in blue lightning bolts and delivers a slash that spawns blue fire.
**Kiva: Zi-O summons a flock of energy bats charging at the opponent.
**Drive: Zi-O delivers three slashes that summon Shift Tire-like projections of Max Flare, Funky Spike & Midnight Shadow with each slash to attack the enemy.
**Ex-Aid: Zi-O delivers three consecutive, magenta-energy coated slashes, with an Ex-Aid 'Hit!' effect appearing with the first two strikes, and a 'Great!' effect on the third one.

==Finishers==
===RideHeisaber only===
To activate a finisher, Zi-O must plug a Ridewatch in the Ridewatch Base of RideHeisaber. The finisher's effect depends on both of the plugged Ridewatch and the current DecadeArmor form.

**Ghost Form: Zi-O conjures several card-like projections towards his enemy, before delivering several Rainbow-energy coated slashes to the target similar to Den-O Sword Form's finisher.
**Ex-Aid Form: Zi-O conjures two card-like projections towards his enemy, before delivering a powerful slash at the opponent, which will then take effect in a few seconds akin to Muteki Gamer's Hyper Critical Sparkling.

===Ziku-Driver + RideHeisaber ===
*: A red glint travels along the blade of the RideHeiseiber before it is set on fire. Zi-O then delivers a fiery slash to repel an enemy's attack, eventually breaking though to produce a massive arc of flame.

==Notes==
*Its name is a combination of the terms Heisei and Saber.
*As a whole, the RideHeisaber resembles a wristwatch, with the blade resembling the strap and the Hand Selector resembling the watch itself.
*It is unknown if the Dual Time Breaks (or Ultimate Time Break) will react towards an Anotherwatch in the same way Ridewatches (through Rider Armors) do i.e. destroying them.
