Yes, stabbing someone is a felony in nearly every case. Prosecutors treat a knife as a deadly weapon, which pushes the charge into felony territory — typically aggravated assault, assault with a deadly weapon, or attempted murder — regardless of how deep the wound ended up being. A misdemeanor outcome is possible on paper but rare in practice, and anyone facing a stabbing allegation should plan around felony-level consequences.
Why a Knife Pushes the Charge to Felony
The FBI defines aggravated assault as an attack intended to inflict severe bodily injury, usually accompanied by a weapon likely to cause death or serious harm. Attempted aggravated assault with a knife falls in the same category even when the victim escapes significant injury.1Federal Bureau of Investigation. Aggravated Assault Courts routinely classify knives as deadly weapons, so using one against another person triggers felony exposure on its own.
At the federal level, assault with a dangerous weapon carries up to 10 years in prison, and assault with intent to commit murder carries up to 20.2Office of the Law Revision Counsel. 18 USC 113 – Assaults Attempted murder alone also carries up to 20 years.3Office of the Law Revision Counsel. 18 USC 1113 – Attempt to Commit Murder or Manslaughter State penalties vary but follow the same pattern: worse intent or worse injury, longer sentence.
What Determines the Specific Charge
Intent
Prosecutors focus on what the defendant meant to do. Grabbing a kitchen knife during a sudden argument reads differently than buying a knife, driving to someone’s location, and attacking them. Premeditation pushes the case toward attempted murder rather than aggravated assault, which can mean decades more in prison. Even without planning, prosecutors often prove intent to cause serious harm from the location of the wound, the force used, and the number of times the defendant struck.
Severity of Injury
The extent of harm directly affects the charge. A wound that requires emergency surgery, damages an organ, or leaves permanent scarring points to the most serious felony classifications. Federal law separates simple assault (up to six months) from assault resulting in serious bodily injury (up to 10 years).2Office of the Law Revision Counsel. 18 USC 113 – Assaults State statutes draw similar lines, and medical records become central evidence.
Who the Victim Was and Where It Happened
Domestic violence stabbings frequently carry enhanced charges. Federal assault law specifically addresses violence against spouses, intimate partners, and children.2Office of the Law Revision Counsel. 18 USC 113 – Assaults A stabbing committed during another crime, in public, or in front of children also invites more serious charges. Other factors that commonly ratchet a sentence up:
- Prior violent convictions, which can trigger habitual offender statutes or mandatory minimums.
- Protected victims — police officers, firefighters, elderly people, or children.
- Multiple victims, which usually means separate charges per victim and sentences that may run back-to-back.
- Location-based enhancements for stabbings on school grounds, in government buildings, or in correctional facilities.
On top of all that, most jurisdictions have sentencing enhancement statutes that tack on additional prison time whenever a deadly weapon was involved. The U.S. Sentencing Commission defines aggravated assault to include any felonious assault involving a dangerous weapon with intent to cause bodily injury.4United States Sentencing Commission. Amendment 614
Prison Exposure
Federal maximums give a useful frame of reference:
- Simple assault: up to six months.
- Assault with a dangerous weapon: up to 10 years.
- Assault resulting in serious bodily injury: up to 10 years.
- Assault with intent to murder: up to 20 years.
- Attempted murder: up to 20 years.3Office of the Law Revision Counsel. 18 USC 1113 – Attempt to Commit Murder or Manslaughter
State penalties often match or exceed those ranges, and some states impose mandatory minimums for violent felonies, leaving the judge no room to go below a floor. Mitigating factors like no prior record or genuine remorse can pull a sentence down within the available range; aggravating factors push it the other way.
The headline number is not the whole story. Federal grant programs have pushed states toward “truth in sentencing” laws requiring violent offenders to serve at least 85 percent of their imposed sentence before parole or early release.5eCFR. 28 CFR 91.4 – Truth in Sentencing Incentive Grants In practice, a 10-year sentence for aggravated assault often means at least eight and a half years actually served. Some jurisdictions have eliminated parole entirely for certain violent offenses.
When Self-Defense Changes the Picture
A stabbing may not result in criminal charges at all if the defendant acted in legitimate self-defense. The core requirement is that the person reasonably believed they faced an imminent threat of death or serious bodily harm, and that the force they used was proportional to that threat. Someone attacked with a deadly weapon who responds with a knife has a stronger claim than someone who escalates a fistfight by pulling a blade.
In federal court and in most states, once the defendant puts forward enough facts to raise self-defense as a live issue, the prosecution must disprove it beyond a reasonable doubt. The defendant does not have to prove self-defense; they have to raise it credibly, and then the government has to knock it down.
More than half of states have stand-your-ground laws, which remove any obligation to retreat before using force in self-defense. In duty-to-retreat states, a prosecutor can argue the defendant should have walked away, which can undermine even a genuine claim. Excessive or disproportionate force — continuing to stab someone who is already subdued, for example — sinks a self-defense argument in any jurisdiction.
Could It Ever Be Charged as a Misdemeanor?
Theoretically, yes. A misdemeanor charge might surface where the wound was minor (a shallow cut during a scuffle), the defendant had no weapon drawn in advance, and the evidence suggests no intent to seriously injure. Even then, many prosecutors file felony charges first and leave any downgrade to plea negotiations. Reducing a felony stabbing charge to a misdemeanor through a plea deal is uncommon because of the weapon involvement, though it happens in borderline cases where facts are ambiguous. Counting on a misdemeanor outcome is a bad bet.
What Else Comes With a Conviction
Restitution to the Victim
Federal law requires courts to order restitution in any case involving a crime of violence where an identifiable victim suffered physical injury or financial loss.6Office of the Law Revision Counsel. 18 USC 3663A – Mandatory Restitution to Victims of Certain Crimes Most states have similar requirements. Restitution covers medical expenses, lost wages, rehabilitation, and related costs like childcare and transportation to medical appointments. It is not optional or negotiable in federal violent crime cases. The court must order it regardless of ability to pay, and the obligation survives incarceration — a defendant who serves a full prison term still owes every dollar on release.
A Separate Civil Lawsuit
Criminal charges are not the only exposure. The victim can file a civil lawsuit for battery and seek monetary damages. The burden of proof in civil court is lower than in criminal court, so a defendant can be found liable even after an acquittal. Damages typically fall into three categories: compensatory (medical bills, lost wages, future earning capacity), non-economic (pain, emotional distress, disfigurement), and punitive, which some jurisdictions allow at several times the compensatory amount when conduct was especially egregious. Using a weapon is exactly the kind of conduct that invites punitive damages. The criminal and civil cases proceed independently, so a plea deal does nothing to block a civil suit.
Loss of Firearm Rights
A felony conviction for stabbing permanently bars you from possessing any firearm or ammunition under federal law, which applies to anyone convicted of a crime punishable by more than one year in prison.7Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Violating that ban is itself a federal felony carrying up to 15 years.8Office of the Law Revision Counsel. 18 USC 924 – Penalties The ban applies in every state.
Voting Rights
The impact depends on the state. A small number of states never revoke voting rights, even during incarceration. The majority strip rights during imprisonment and restore them automatically on release or completion of parole. About 10 states impose indefinite restrictions for certain offenses, requiring a governor’s pardon or a separate petition. Check your state’s rules; restoration is far from automatic everywhere.
Employment, Licensing, and Housing
A violent felony shows up on background checks and closes off many career paths. Federal employment is technically open to people with criminal records for most positions, but specific statutes ban employment based on certain convictions, and practical barriers are significant.9USAJOBS. Can I Work for the Government if I Have a Criminal Record? Health-related occupational licenses are exempt from ex-offender protections in nearly half of states, which can permanently block entry into nursing, pharmacy, and similar fields. Private employers are not required to hire anyone with a violent crime record, and many won’t. Landlords routinely run background checks, and a violent felony is among the most common reasons for a denied application. Public and subsidized housing programs often impose additional restrictions on applicants with violent crime convictions.
