This post is about edged weapon training for. Edged weapon incidents are rare in many workplaces, but the consequences can be severe.
That combination creates a training problem. If the risk is overstated, staff may become fearful, overconfident, or drawn into unsafe ideas about “dealing with knives”. If the risk is ignored, staff may be left with no practical plan for one of the most dangerous situations they could face.
Good edged weapon training has to be honest.
For most non-police, non-specialist staff, the priority is not disarming, fighting or closing distance. The priority is recognition, distance, barriers, escape, communication, lockdown or withdrawal, calling emergency support, and protecting life.
For specialist teams whose role may require closer intervention, the training still begins with decision-making, not technique.
The most important question is not “What move do we teach?”
It is: “What should this person realistically do, in this role, in this environment, if an edged weapon appears?”
The first principle: do not make the situation worse
An edged weapon changes the risk immediately.
Distance matters. Barriers matter. Exits matter. The presence of other people matters. The person’s intent, emotional state, movement, and access to others all matter.
Training must help staff understand that bravado is dangerous. A person with a knife is not a training-room problem. They are a serious threat, and even skilled people can be injured very quickly.
For most staff, the safest options are likely to be:
- Create distance
- Get behind a barrier
- Move others away
- Leave the area if safe
- Lock down or secure space where appropriate
- Call police or emergency support
- Communicate clearly with colleagues
- Avoid attempting physical intervention unless there is no other option and the role requires it
This is not cowardice. It is professional risk management.
Prevention still matters
Edged weapon training should not begin at the moment the weapon is visible.
Before that moment, staff may be able to reduce risk through better awareness, environmental design and procedures.
Prevention may include:
- Search or screening arrangements where lawful and appropriate
- Clear reporting of threats
- Managing known high-risk individuals
- Improving sight lines and exits
- Reducing isolated working
- Securing objects that could be used as weapons
- Staff briefings around specific risks
- Stronger communication between teams
- Clear escalation routes
In some settings, the risk may be linked to robbery, street violence, domestic abuse, patient distress, gang-related issues, intoxication, mental health crisis, or enforcement activity. The training should be shaped by the actual context.
A generic “knife defence” course is rarely appropriate.
Reading the build-up
Not every edged weapon incident gives warning signs, but many concerning situations do build.
Staff may notice:
- A person repeatedly touching a pocket or waistband
- Sudden changes in emotional intensity
- Threats involving a weapon
- Attempts to close distance
- Fixation on a grievance
- Scanning for exits or targets
- Concealing one hand
- A group dynamic shifting
- A person becoming quieter and more purposeful
These signs do not prove a weapon is present. They do indicate that staff should create distance, call support, and reduce exposure.
Training should help staff act on concern early rather than wait for certainty. Certainty may arrive too late.
Distance, barriers and movement
The core physical skill for most staff is not a disarm. It is movement.
Can they move away? Can they place something between themselves and the threat? Can they guide others out? Can they avoid being trapped in a corner, corridor, vehicle or small room? Can they keep enough distance to make decisions?
Training should include:
- Maintaining reactionary distance
- Using tables, counters, doors, vehicles or furniture as barriers
- Moving at angles rather than straight backwards where appropriate
- Avoiding dead ends
- Knowing exits
- Communicating movement to colleagues
- Prioritising vulnerable people nearby
This practice should be realistic and role-specific.
A hospital ward, shop floor, school reception, car park, custody setting, public transport environment and office reception all create different options.
Communication during an edged weapon threat
Talking may help in some situations and may be pointless or unsafe in others.
Staff need simple principles:
- Keep language short
- Avoid sudden movements
- Do not threaten or challenge unnecessarily
- Create space while speaking
- Do not argue about the person’s grievance
- Give clear instructions to colleagues or bystanders
- Prioritise escape and containment over persuasion
A person holding a weapon may be highly emotional, intoxicated, mentally unwell, frightened, or determined. Staff should not rely on verbal de-escalation as if words alone can control the risk.
Communication is useful when it supports distance, time and safety.
Specialist roles need specialist training
Some roles may have a duty to intervene in higher-risk situations. Police, secure healthcare teams, certain security teams, and specialist operational staff may require more advanced training.
Even then, credible training should not romanticise edged weapon encounters.
Specialist training should include:
- Legal authority and duty
- Team tactics
- Communication under pressure
- Use of protective equipment where relevant
- Movement and positioning
- Emergency medical considerations
- Weapon awareness
- Stress exposure
- Scenario decision-making
- Post-incident evidence and reporting
Physical skills should be realistic, pressure-tested and governed by clear policy. They should never be sold as guaranteed solutions.
There are no guaranteed solutions in an edged weapon incident.
After the incident
After an edged weapon incident, even if nobody is injured, staff may be seriously affected.
There may be shock, fear, anger, guilt, intrusive images, sleep disturbance, or anxiety about returning to the same place. Staff may also question whether they did enough, even when withdrawing was the correct decision.
The organisation should have a clear post-incident process:
- Immediate safety and medical checks
- Police liaison where appropriate
- Evidence preservation
- Welfare support
- Manager follow-up
- Debrief focused on learning
- Review of environment and procedure
- Communication with affected staff
- Training updates if needed
A serious near-miss should be treated as important learning, not dismissed because no physical injury occurred.
Common weaknesses in edged weapon training
The first weakness is teaching disarms to people whose role is to withdraw.
This can create dangerous overconfidence.
The second weakness is making training too dramatic.
Sensational training may feel exciting, but it can distort judgement. Staff need calm, practical decisions, not adrenaline entertainment.
The third weakness is ignoring the environment.
A classroom drill does not prepare people for a counter, corridor, vehicle, ward bay, stairwell or public street unless the training deliberately addresses those spaces.
The fourth weakness is failing to connect training to policy.
Staff need to know what the organisation expects them to do. If policy says withdraw but training implies intervention, the organisation has created confusion at the worst possible moment.
A practical first step
Start with role clarity.
Ask:
- Who might realistically encounter an edged weapon?
- In what setting?
- What are they expected to do?
- Are they expected to withdraw, contain, protect others, or intervene?
- What support will arrive and how quickly?
- What environmental controls already exist?
- What incidents, threats or near-misses have occurred?
- What does current training imply staff should do?
Then build training around the answers.
For many organisations, the first training priority is not physical technique. It is a clear plan for recognition, distance, communication, lockdown, escape and emergency response.
Edged weapon training for: What good looks like
Good edged weapon training is calm, serious and realistic.
It does not create heroes. It creates people who understand the risk, know their role, create distance, protect others where they reasonably can, and make defensible decisions under pressure.
For specialist roles, it builds capability without pretending the risk can be controlled neatly. For non-specialist roles, it reinforces the safest priority: get away, get others away where possible, and get help.
If you would like to review edged weapon risk and training for your organisation, we can help you clarify roles, assess environments, and design practical scenario-led training that reflects what staff should realistically do.
