Radius Factor Self-Protection ✖️ Survival ✖️ Preparedness
Train to Skill Up Fast, Maximize & Adapt.

👉 “Stick” vs empty-hands self-protection training: it’s not easy if the attacker is trained. Depending on the type of stick or club, with the right speed and power, it can break bones and cause life-threatening injuries. (Now imagine what a long blade can do.)

So…

Awareness matters.
Range matters.
Angle matters.
Timing matters.
Footwork matters.
Tactic matters.

And, of course, speed, power, body mechanics, etc., will matter.

Obviously (well, maybe to some), if you see/know he has a weapon and you’re empty-handed, you need to take immediate action. That is, range all the way out (and on an angle) or close the gap to extreme close-quarters.

You also need to identify the transitional point where you may not be far enough out of range (or not close enough) to avoid being hit.

In Pekiti-Tirsia, fail-safes are defined.

Putting skills to the test can done in various ways. This is one way but not all.

If armed, trained and in range, the unarmed person has very little chance without the right training. Even with training it’s extremely contextual, difficult and needs a simple yet detailed process.

More on the subject on a follow-up video.

A pen as a force-multiplier for self-defense? Indeed. Whether it’s a tactical pen, plastic ballpoint pen, pencil, and anything of the like, they can be very effective with very little training.

Plus, pens and pencils can be found just about anywhere.

Try it out at a Radius Factor class.

Part One: You have to move.

7 yards, 5 yards, 3 yards, mobility is life. If you stand still during a dynamic bladed attack, you do so at your own peril.

No matter how fast you can draw, the clock had already started.

The threat is closing the distance. You’re now aware. The threat is now at 3 yards. You draw from concealed in place. You’re hit, even if you get a shot off.

If there’s one thing our lineage of Pekiti-Tirsia teaches as an inherent methodology, it’s the understanding of a Range-Angle-Timing triangle, recognizing the attack, as well as using dynamic footwork off the line of attack increases your survival (and increases the ability to dominate the combat).

Think tactically, not only how fast your draw can be. Sub-second draws are awesome, but if not coupled with movement at the right time m, range, and angle, then the sub-second draw is a superficial standard.

The speed of the attack and follow-through of a bladed weapon if often overlooked.

Part Two will demonstrate how developing footwork (the take-off) at close-range at the right angle can increase your survival and position of advantage.

Equaling the force of a powerful incoming strike/attack is critical for slowing the strike (or redirecting), as well as possibly damaging the arm (and shoulder joint).

Thus, the reason mechanics to achieve an angle of incidence (perpendicular) and transfer power are part of the principles of the Pakal in Pekiti-Tirsia.

You may not always get the full power counter-strike (ie. “tapping”) to the weapon-bearing arm, but as long as you make contact and redirect the attack, you increase the percentage of surviving.

Learn and train to maneuver and displace your body from the line of attack, understand pattern recognition (visual perception and how to control/respond to the interaction), along with the range, timing, energy, rhythm, and factoring the full travel of the follow-through of the attack.

Then strike, grapple/outbalancing if needed, and/or level up to an equalizer when possible.

Perception and dynamic footwork maneuvering (whether evading or closing the distance) are both quintessential to self-protection and earning the opportunity to get to your equalizer.

It also requires an understanding of range and timing with an effective training methodology to build the skill set of when, where and how to apply relevant tactics.

Standing still will be disastrous.

Mobility is life.

How’d ya get there? Isolation is fine if you also train the lead up to the isolated point of instruction.

For example, teaching (or learning) what to do when you have control of a weapon-bearing limb. Great, I like it. BUT how was the arm acquired? Was it static? Was it indexed?Was it dynamic? If dynamic, at what range did you start? How did you engage?

What method was used to get control of the arm and at what speed, and at what point in the depth of travel of the moving arm?

Can the timing be explained? Was a maneuver used to position you offline of the attack? Did you move to the outside or inside? What was the method used?

Did environment play a role? Were you on the ground? Were you standing and in the middle of an empty-hand fight then the weapon was produced?

Train context, keep it all connected, and only train in isolation when working specific skill builders.

And always ask yourself, “How I get here?”

Part of a Countermeasures Schema.

👉 Never stand in place. Go dynamic. An isolation drill is one thing, a tactic is another.

Also, have an EDC. No EDC? Get to an equalizer. No equalizer? Use environmental barrier. No environment? See number one.

Don’t think in terms of “techniques”, especially not isolated solutions when presented with an armed attacker. Dynamic situations will adapt. So, you must be adaptable.

Side note: the trainer has been a handy training tool.

“Controlling the hands” (eg. weapon-bearing limb) can be achieved in different ways.

Either by a grapple or attachment, striking, checking, and other times by range, angle, position, or environment.

Not controlling what the hands do can spell disaster. Likewise, retention of your everyday carry is critical.

01/06/2026

I prefer open hand strikes, slaps, hammerfists, forearm hacks, elbows, knees and direct low-line kicks when training or using kickboxing or kenpo. However, “boxing” should be a part of your repertoire even if only to understand it, especially how to attack the incoming strikes.

Not that I don’t like to punch the hinge of the jaw, plexus, kidney or another soft target, it’s just that they’re more susceptible to being broken if not conditioned, protected, or used precisely.

So, use precision when punching (which takes longer to develop and condition) in self-defense.

Sparring with gloves and boxing, absolutely fine. You’ll pull valuable things from it (when trained strategically). Like, how an elbow will break a hand.

For combatives, change your mindset to destroying whatever is in the space between you and opponent (including the punching hands and the rest of the body targets).

Sufficiently breaking a hand will extremely diminish the ability to punch, grip or manipulate a tool/weapon. Which means, it’s a two-way street, so decide which side of a busted hand you’d rather have (yours or destroying your opponent’s).

(Side note: boxing and kickboxing are insufficient for weapon countermeasures.)

For those that think palm strikes shorten your range vs punches, yes, they do. But elbows do, too. So, get better at footwork, angles and setups.

01/02/2026

Every self-protection and combat scenario has range, timing, environment and context.

That said, your training and skillset should integrate whether it’s striking, grappling and/or force-multipliers (especially force-multipliers).

Get the skillset as fast as possible, make it contextual, and keep what’s useful—no matter if it’s the force-multipliers of Pekiti-Tirsia, striking, grappling, or even conditioning. What you train in the realm of self-protection and combat should be congruent.
