To get all Darth Maul on enemies, press B to brandish and wield a double-edged light saber. Press Down to put it away.”
— Description • Nintendo Power (Volume #134)
Spark + Cutter (also called Double-Bladed Laser Sword or Light Saber) is a Power Combo from Kirby 64: The Crystal Shards. Kirby gets it by mixing Spark and Cutter. Attacking with the blade swings it in a wide arc, protecting Kirby from projectiles fired from most angles. Even when not swung, the blade has a constant hitbox, damaging any enemies that run into it and protecting Kirby's back. While the blade is out, however, Kirby can only jump once, and is not able to float. Crouching sheathes the blade.
Kirby can use this ability to obtain a Crystal Shard in Stage 4 of Shiver Star, in which he needs to destroy a yellow and green cage.
Alternatively, it may be intended as a homage to the twin beam sword wielded by Char Aznable's MS-14S Gelgoog Commander Type mecha in the original Mobile Suit Gundam anime series. The pointed design and yellow color scheme of the weapon resemble this sword more closely than it resembles Darth Maul's weapon. This reference would be lost on many players outside of Japan, where the anime is most recognized, so Nintendo Power may have attributed the ability's likeness to the Star Wars franchise, which is better-known in North America.
