Do you teach weapon defense?

Some, and carefully. I have trained around weapon work for twenty-five years, and the first thing that experience teaches you is how bad the odds are.

So no technique tutorial on a web page, and no promises. What a page can honestly give you is the principles.

Distance is everything. Every weapon problem gets worse the closer you are. Most of the answer is space and an exit, not hands.

If they want your property, give it to them. Wallet, phone, keys, car. None of it is worth what you would be gambling. Throw it one way and move the other.

Assume you will not see it. People rarely show a knife first. If the situation smells wrong, treat it as armed and act on that early, while early is still available.

A weapon you cannot see is a reason to leave, not a reason to close the gap.

A disarm is a last resort against a wall, not a plan. If somebody is already cutting, already committed, and there is genuinely nowhere to go, that is a different and much worse situation. It gets trained slowly, with a person in front of you, and it never gets taught as the first answer, because the day you treat it as the first answer is the day you close distance you did not have to close.

The honest maths is this. People who are good at this get cut. That is not a reason to skip the training, it is a reason to be clear about what the training is for: recognising it earlier and being somewhere else.

So the upstream work matters more here than anywhere. Where you park, what your hands are carrying, who is behind you, when you leave. See avoiding trouble. The same holds when there is more than one of them and the answer is identical: distance and an exit. See what about more than one person.

All of it sits downstream of the one skill that would have solved it earlier, which is noticing. Weapons situations almost always announce themselves first. The wrong question. The wrong distance. The hand that stays out of sight. See the single most important self-defense skill.

Using force has serious legal consequences, and so does carrying anything yourself. Nothing here is legal advice. Talk to a lawyer about what is lawful where you live. If you want to work on this, message me and say so directly.
