Knife Defence — The Realistic Position

Can You Actually Defend Against a Knife Attack?

In Brief

Yes — a qualified yes. A knife is one of the most dangerous threats a civilian can face, and no training guarantees the outcome. But Krav Maga Global treats knife defence as a core, integrated part of its system and trains it regularly and as realistically as safety allows, to give you the best chance of success: awareness, distance and escape where possible — and at close range, defending, taking control of the knife arm and disarming the attacker.

What matters is how the training prepares you to respond. KMG combines awareness, distance management and escape with physical knife defences practised under progressively increasing pressure — so students learn to respond when the attacker is already at close range, rather than relying on techniques performed against a cooperative partner.

This is the position the KMG system takes, and it shapes how knife defence is actually trained in New Zealand.

What does a real knife attack actually look like?

Real knife attacks are fast, close, and chaotic — not the choreographed exchanges shown in films or sport demonstrations. They are usually short. They usually happen at conversational distance or closer. And the attacker is rarely holding the blade out in front of them like a fencer.

More often, the knife is concealed until the moment of impact. The attacker closes the gap quickly and delivers a rapid series of stabs or slashes at vulnerable areas — neck, torso, the inside of the arms. Many victims do not realise they are being stabbed until afterwards. There is no warning posture, no pause, and no opportunity to "set up" a clean defensive technique.

The combination of speed, surprise, and proximity is what makes knife attacks so dangerous. It is also why stylised knife defence training may not prepare someone for an unpredictable attack.

Where do knife disarms fit in?

Disarms are an important part of the KMG system. At close range, when escape isn't possible, taking control of the knife arm and disarming the attacker is the ultimate goal — because removing the knife is what ends the threat. If a chance to get away safely opens up first, you take it.

If you can avoid the weapon or get away before contact, you do. But many knife attacks start at close range, with no chance to escape. Then the KMG approach is a clear sequence: defend against the stab or slash, take control of the knife arm, counter-attack, and disarm — then get to safety.

What KMG doesn't do is teach a disarm as a grab for the knife from a standing start — the kind of move that looks good in films and fails under pressure. A disarm is the end of a sequence that begins with a defence and control, and it is trained and pressure-tested that way. A knife in the hand of someone determined to use it is an extreme threat to anyone, so the training is built around what holds up in reality, not false confidence.

This is part of the system developed under Eyal Yanilov, head of Krav Maga Global, and taught at every KMG club in New Zealand.

"If you can get away, get away. If the attacker is already on you, defend, take control of the knife arm and take the knife — that's how the threat ends."

How does Krav Maga actually train knife defence?

KMG knife defence training is layered — awareness first, then distance, then disengagement, with physical defence as the last option. Each layer reduces the chance of needing the next one.

The layers describe the order of priority in a real situation — not the order you learn them in. Physical knife defences are part of the curriculum from the first level, trained alongside the decision-making that tells you when to use them:

  • Awareness. Recognising pre-attack indicators — hands hidden, agitation, closing distance without reason, suspicious objects in the hand. Some knife attacks have warning signs before they become physical; others come with none — which is why the other layers matter.
  • Distance and positioning. Creating space, putting barriers between yourself and the threat (a chair, a car, a doorway), keeping the attacker at a range where you have time to react.
  • De-escalation and disengagement. Verbal de-escalation, controlled retreat, getting to a safe location or to other people. The goal is to make the situation end without physical contact.
  • Physical defence. If contact is unavoidable — defending against the stab or slash, protecting vital targets, taking control of the knife arm, counter-attacking and disarming the attacker, then getting to safety.

None of these layers is "optional advanced material." All of them are taught from beginner level, because the system is designed for ordinary people in real situations — and that includes disarms trained under realistic pressure, not performed in an ideal setting.

Our approach: what KMG knife defence looks like in practice

The priorities never change — stop the danger and get away — but the physical response depends on distance, what's around you, and how the attack is coming. These are the principles KMG New Zealand trains:

Krav Maga Global is an integrated system for dealing with unpredictable, dynamic threats and attacks — not a collection of single techniques. Knife defence is built on the same core movements and principles you use against every other kind of threat, so what you learn in one area reinforces the rest.

1

At a distance: kick and keep them there

If the attacker is still at range, your legs are your longest weapon. A kick can stop the attacker's forward movement and keep them — and the blade — at a distance, creating the moment you need to escape.

2

Use what's around you

If a suitable common object is within reach — a bag, a chair, a jacket, an umbrella — use it to block, strike, or put a barrier between you and the knife.

3

At close range: deflect, block and take control

When the attacker is already on you, KMG has a wide range of techniques for dealing with threats and strikes — blocking or deflecting the stab or slash, then taking control of the knife arm. Controlling the arm sets up the disarm — and when escape isn't possible, taking the knife away is the ultimate goal, because it removes the threat.

4

Built for how attacks really vary

The techniques are designed to work across different types of knife, different grips, threats as well as attacks, and stabs and slashes from different angles — including if the situation goes to the ground.

5

One integrated system, not a list of techniques

Knife defences share common components, movements and principles with how KMG deals with punches, grabs, chokes and other weapons. Training addresses a wide range of knife threats and attacks in combination with other attacks and real-world elements — multiple attackers, different environments, and protecting others. The goal is a response that adapts to the situation, not a memorised move for each scenario.

Part of training from day one

Knife defence is included in Practitioner Level 1 (P1) of the KMG curriculum, so new students start learning some of these techniques from their first classes. Speed, pressure and complexity build as training progresses.

What does pressure-tested training actually mean?

Pressure testing is how training checks whether skills hold up as conditions get harder — instead of only working under cooperation. Without it, knife defence becomes a choreography exercise.

In KMG classes, knife defence is trained progressively. Early drills are slow and cooperative so the technical movement can be learned. Then the speed increases. Then the attacker stops cooperating — varying angle, timing, and intensity. Then the defender starts from a disadvantaged position — surprised, distracted, already moving, in a confined space. Then knife attacks are combined with other attacks and real-world complications: more than one attacker, cramped or unfamiliar environments, and someone else to protect.

The goal is to find out what holds up when the conditions get harder. A technique that only works when the attacker stands still and stabs once on cue is not a technique you can rely on. The training environment is built to expose that gap, not hide it.

This is also why training is selective about what it teaches. Techniques are chosen for simplicity and reliability under stress, not for visual impressiveness. Gross-motor responses, vulnerable-target principles, and protecting the centreline tend to survive pressure testing. KMG disarms are built and tested the same way — as decisive actions performed once the knife arm is controlled, not intricate moves that only work on a cooperative partner.

What about the legal side of defending against a knife in New Zealand?

In New Zealand, you are legally allowed to defend yourself against a serious threat — but the force you use still has to be reasonable in the circumstances as you believed them to be. This is set out in section 48 of the Crimes Act 1961.

The presence of a weapon changes what counts as reasonable. A knife is a lethal threat, and a defender's response can be more decisive when facing a lethal threat than when facing an unarmed scuffle. But the same legal principle still applies: the force used has to be connected to stopping the danger, and whether the threat had ended — or whether you could safely have got away — is relevant to whether the force was reasonable.

This is one reason why escape-first thinking is not just safer — it can also be easier to justify legally. A defender who got away from a knife situation is in a much stronger position than one who stayed engaged longer than they had to.

Who should train knife defence?

Knife defence is a core part of the KMG curriculum, trained seriously and regularly — not an advanced specialty. Every adult member training with a KMG-affiliated club in New Zealand is exposed to weapon defence material as part of the general system.

The training is not aimed at people who expect to face knife attacks regularly. It is aimed at ordinary adults who want their training to address the full range of real-world threats — including the dangerous ones — rather than pretending those threats do not exist.

It is also calibrated to what is realistic. Core knife defences are part of Practitioner Level 1, so beginners start learning them from their first classes — at a speed and intensity matched to their experience. Pressure, complexity and the more advanced control and disarming work build as training progresses, alongside the recognition, distance and decision-making skills that work for everyone, regardless of size, strength, or experience.

Common Questions

What people ask about knife defence

Yes — a qualified yes. A knife attack is one of the most dangerous situations in self-defence and no training guarantees the outcome. But Krav Maga Global treats knife defence as a core, integrated part of the system and trains it regularly and as realistically as safety allows, which gives you the best chance of success. Avoid the weapon and escape where you can; at close range, when escape isn't possible, defend, take control of the knife arm and disarm the attacker.

Yes. Disarms are an important part of the KMG system and, when escape isn't possible, the ultimate goal in a close-range knife situation, because taking the knife away ends the threat. They are trained as the end of a sequence — defend the attack, take control of the knife arm, counter-attack, then disarm — rather than as a grab for the knife from a standing start, which rarely works under real pressure.

Yes. Knife defence is part of Practitioner Level 1 (P1) in the KMG curriculum, not an advanced specialty, so beginners start learning core knife defence techniques from their first classes. Speed, pressure and complexity build progressively as training continues.

Film knife fights are slow, choreographed, performed at distance, and highly visible. Real knife attacks are fast, close, often concealed until the moment of impact, and over in seconds. Training that prepares you for the film version will not prepare you for the real one — which is why pressure testing matters.

Yes. Under section 48 of the Crimes Act 1961, you can use force in defence of yourself or another person, provided the force is reasonable in the circumstances as you believed them to be. The presence of a lethal weapon changes what counts as reasonable, but the same legal principle still applies — and whether the threat had ended, or whether you could safely have escaped, is relevant to whether the force was reasonable.

Yes — escape is almost always the best outcome in a knife situation. Getting to a safe distance, behind a barrier, or to other people is much more reliable than any physical defence against a blade. KMG training treats escape as a primary skill, not a fallback.
