This boomerang slices grass and vines! If it skims land your friends are burning with fire or drenching with water, it will take on those elements. And if it absorbs wind, it can fly upward. Wreak havoc with your Final Cutter!”
Cutter gives Kirby the ability to utilize an infinite amount of curved, boomerang-like blades that appear on the cap he acquires. If the cutter misses Kirby on its return, it will keep going on behind him. Players can use this tactic to attack enemies behind Kirby without turning around. In later games, Kirby can guide the blade upwards and downwards after throwing it.
In Kirby 64: The Crystal Shards, the "blade" Kirby uses is actually his own face, which peels off his body and travels forward. In Kirby's Return to Dream Land, Cutter Kirby can charge his cutter to make it larger and more powerful. Doing this also allows it to bounce off of surfaces several times.
Kirby tosses the blade from his hat in front of him (it reappears immediately). In most games it can be controlled with ↑ or ↓. By causing the cutter to miss Kirby on its way back, enemies behind Kirby can be attacked without him turning around.
Possession of this ability's Ability Scroll makes the blade larger, more powerful, blue colored, and enables it to pass through enemies, making it able to hit some more than once, and go through certain walls.
Hold 1/B, then release
Kirby holds and charges a Cutter Boomerang in his hand until it enlarges and flashes. This cutter is larger and more powerful, and will also bounce off of walls several times before disappearing.
Kirby dashes forward, swinging the cutter upward like a sword.
18 (initial hit), 16 (dash momentum)
Hold B/Y/1 (Midair)
Kirby throws a Cutter Boomerang like normal, but holds out another one while doing so, causing extra damage to anyone in melee range.
Down + B/Y/1 (Midair)
Kirby holds his cutter in front of him as he falls down damaging enemies. By dashing in midair the attack goes slightly faster.
B/Y/1 (near enemy)
Kirby attacks enemies using his Cutter as a sword and slashes the enemy
12 (1st hit), 8 (2nd hit)
12 (1st hit), 10 (2nd hit)
Nonstop Cutter/Final Cutter
Up/Down/Forward + B/Y/1 (near enemy) or mash 1 near enemy (comboed from Cleaving Cutter)
Kirby jumps in the air and brings down his blade in a huge slash, generating an energy wave on the ground that explodes on contact with a wall. This move is sometimes used by Sword, but with the first two slashes removed.
8 (rising slash), 32 (falling slash and shockwave - only one can hit the enemy); max damage w/ Cleaving Cutter = 46
Kirby tosses a cutter from his hat. Cutter Boomerang is parallel to ground in 3D Battle Modes, but perpendicular in 2D Battle Modes.
B during jump
Kirby throws a downwardly-angled cutter. The cutter's spin is perpendicular to the ground instead of parallel, and it does not return to the thrower.
Kirby holds and enlarges his cutter. The thrown cutter can bounce off walls. Similar to Hyper Boomerang, but does not return to the thrower. Kirby can move while charging.
Kirby slashes his Cutter upward, followed by a downward slash into the ground, creating a shockwave. Works more like his Smash Bros. variant, being able to activate whenever instead of only when near an enemy.
In the Super Smash Bros. series, Final Cutter is Kirby's Up Special Move. Kirby slices upwards and then downwards, blade in front of him. Upon landing, he will create a shockwave. In Super Smash Bros. for Nintendo 3DS and Wii U, Kirby can change his Final Cutter using Custom Moves. He can now also use Wave Cutter or Upper Cutter. Wave Cutter acts the same as Final Cutter, albeit the blade can't damage opponents, but upon landing, he will send powerful rocks flying. Upper Cutter allows Kirby to initiate a powerful slice upward, but no slice downward, putting Kirby into his helpless state. This move is similar to Marth's Dolphin Slash.
Cutter Kirby in Kirby: Right Back at Ya! uses the same duck hat as the later games, and appears whenever Kirby manages to inhale things like blades and saws (anything that's sharp except for an actual sword). It is revealed here that the Cutter that Kirby uses is stored on the hat when it isn't in use. This version of Cutter is based on the Kirby Super Star version, but with new attacks. Cutter Boomerang is the primary attack, but Kirby often uses Final Cutter to finish off enemies.
In the transformation sequence, the Cutter cap lands on Kirby's head and spins before bouncing and coming to a stop in the proper position. The Cutter appears and flies around Kirby, then lands on his cap from behind.

The meaning of the Cutter ability varies vastly from language to language. Its Japanese name, カッター (Kattā), meaning Cutter, is the same as its English name; however, it is the only name to mean that. The German name, Bumerang, means Boomerang; the Spanish name, Cuchillo, means Knife; the French name, Trancheur, means Slicer; the Italian name, Lama, means Blade; and the Chinese name, 弯刀 (Wān dāo) means Scimitar.
The design of Cutter from Kirby Super Star onwards may have been inspired by the Eye Slugger, an iconic fictional weapon used by the superhero Ultraseven in the 1967 tokusatsu TV series of the same name. This is especially apparent in how the blade attaches to Kirby's hat like a mohawk hairstyle, and is removed before being thrown.
Cutter's hat seems to draw inspiration from Arale Norimaki’s baseball hat design-wise, as well as Chi-Chi's helmet from the early seasons of Dragon Ballin terms of usage.
In most games, Kirby can throw multiple cutters, but in Kirby 64: The Crystal Shards, he can only fire one at a time because he uses his own face as the cutter. Though humorous, it leaves Kirby vulnerable; he is unable to fly or attack again until his face returns to his body.
Kirby could use Link's boomerang after swallowing the latter in the original Super Smash Bros., similar to the Cutter ability. In later Super Smash Bros. games, Link uses a bow and arrow as his neutral B, therefore Kirby gained a bow after swallowing him instead of a boomerang.
The bill of Cutter Kirby's hat in the games is white, but it is yellow in Kirby: Right Back at Ya!.
