An action that occurs when a player swings their stick at an opponent, which can result in a penalty if considered aggressive by the referee. A slash is generally not penalized if the slash misses or impacts the player on their pants or pads. Slashes are penalized when the slash is not considered a play on the puck and is seen as forceful or powerful and impacts the opponent on the body, stick or near the hands.
Slashing is defined under Rule 61.1 in the Official NHL Rulebook.
A slashing penalty may lead to a minor, major or game misconduct depending on the severity of the slash. A penalty is more likely to occur if the player being slashed during a scoring chance or if their stick is broken.
