John Kavinsky was found guilty of aggravated assault.
The court considered aggravating factors, including the serious and life-threatening injuries inflicted with a knife, the deliberate act of carrying a weapon to a social event, the motive of resisting efforts to prevent drunk driving, and attempts to conceal evidence.
Mitigating factors included his youth, lack of prior criminal record, genuine remorse, and positive prospects for rehabilitation.
The court emphasized denunciation and general deterrence, rejecting a suspended sentence or intermittent custody.
A custodial sentence of 21 months was imposed, with credit for pre-sentence custody, followed by two years of probation, a lifetime weapons prohibition, a DNA order, forfeiture of the knife, and a victim surcharge.
