There are many attacks in the Smash Bros. series that make use of the slash effect. In most cases, the effect is used by attacks involving sharp objects. It is easily identifiable by the visual effects generated on impact: a white and blue circular slash in Super Smash Bros. and Super Smash Bros. Melee, and a crescent-shaped visual effect from Super Smash Bros. Brawl onward.
There are two slashing sound effects in Super Smash Bros., while Melee and Super Smash Bros. 4 have three each. In Brawl, there is only one sound played at differing speeds and pitches based on the attack used. For example, Link's down aerial has a low pitch, whereas Bowser's neutral attack has a medium pitch. Not all slash attacks use these sound effects, however: many of Young Link and Toon Link's sword attacks, alongside Roy's non-sweetspot sword moves, use punching sound effects.
Super Smash Bros. 4 introduces the stab effect, a variant of the slash effect used for a handful of attacks, such as Luigi's forward smash and Bowser's up smash. The two effects are functionally identical, differing only in visuals: the stab effect is shown as a straight line in the direction of the attack, instead of as a crescent.
