Brian-B.Group OrganizerPhiladelphia, PAPost #: 32Send an Email Post a GreetingHere's my notes from our "Shredder Seminar" on Sat., Mar. 24th, 2012. This was a 90-minute self-defense seminar for men & women of all skill levels. The purpose was to introduce participants to one of the most effective unarmed self-defense tactics for close quarters combat - the "Shredder". Developed by Canadian self-defense trainer Richard Dimitri, the Shredder is a rapid barrage of short range strikes, rakes, rips, gouges, and neck cranks that completely overwhelms an assailant. It's advantage is that it can be learned in a short time and can offer a powerful self-defense tactic to even smaller, weaker or less trained individuals. It will often be difficult for a smaller person to knockout a larger opponent with punches & kicks, throw them, joint lock them, or choke them out. However, a smaller person can always injure a larger opponent with attacks to the soft tissues of the face & neck - i.e. eye gouge, trachea crush, jugular pinch, ear rip, fishhook, face rake, neck bite, etc.

To see what the Shredder looks like applied full speed, check out this video clip:

The man demonstrating the Shredder in this clip is the concept's creator, Richard Dimitri. As you can see, he can safely demonstrate it by not fully applying the rakes, rips & gouges to his partner's face. Essentially, he is just simulating these deadly tactics by vigorously rubbing his partner's face and twisting his partner's head in different directions. This low-force application of the Shredder is referred to as "face wiping" or "face washing".

For beginners, it's necessary to slow the action down and occasionally "freeze frame" the situation so they can understand which of their body weapons are closest to the targets on their attacker's body. This is referred to as "tool & target development". This is well illustrated in this second clip, which works from an initial start where both attacker & defender are standing with their palms out & touching - something known as the "Mirror Drill". As you can see from the clip, slowing the action down in the initial phase of training allows you to easily determine what opening your partner is presenting and how you could attack them: - Shredder Mirror Drill: http://www.youtube.co...

When you first start practicing the Shredder, you probably won't be able to think of the wide range of attacks Richard Dimitri demonstrated in that clip. You'll most likely concentrate on just wiping your training partner's face rapidly and twisting their neck, and that's really the most important way to start. The face wiping is very disorienting, and the neck twists break their balance and often make your partner bend over or fall to the floor. Once you've put them on the defensive, you're better able to see the openings to insert strikes like headbutts, elbows, hammerfists, palm strikes, knees, foot stomps, etc. And since you've got control of their head and you've put them off-balance with the neck twists, you can also take this opportunity to bounce their head off any nearby hard object (a brick wall, table, car, street sign, window pane, etc.) or toss them down so their head hits the ground quite hard.

One of the most important parts of the Shredder is "trapping" or "anchoring" - i.e. you must get close to your opponent and get a hold of them so they can't easily disengage after your first couple attacks. If they do, they can recover and then renew their attack. You must inflict enough damage to them that they are unable to continue their attack, or at least enough to cause them to fall to the ground which will allow you the opportunity to escape & run away. Typically, trapping them is done by either (1) grabbing the back of their head with one hand (known in wrestling as a "neck tie"), (2) wrapping your arm OVER their upper arm (known as an "overhook"), or (3) wrapping your arm around their head/face (like a front, side or rear headlock). It can also be done by (4) wrapping your arm UNDER their upper arm & grabbing their shoulder (known as an "underhook") or (5) wrapping around their waist & grabbing their ribs or lat muscle(known as a "seatbelt"), although this makes it harder for the trapping hand to transition into a facial attack. The trapping principle is illustrated in the following clip:

- Importance of Trapping: http://www.youtube.co...

Initially, we practiced using the Shredder off the "passive stance" - it's similar to a standard kickboxing stance with the hands held up, but they're open, palms out. This gives the impression, "Hey, calm down. I don't want to fight," and it allows you a chance to talk the person down. This is a good stance to use in any real-life altercation that you fear may turn violent. If you can't defuse the situation, having your hands up allows you to block your opponent's attempt to strike your head or grab you, and it also allows you to quickly counterattack them. Quite often, if an aggressive person feels they can intimidate you, they'll get very close, almost face-to-face. If you have your hands up, you can slam a palm strike into their face and start applying the Shredder before they have time to react.

This is how we initially practiced using the Shredder: (1) you have your hands up in a passive stance, (2) the opponent gets up in your face & makes an aggressive or threatening motion, (3) you simultaneously wrap their arm to trap them & palm strike their chin, then rake their face,(4) you unwrap your other arm from theirs and use it to now wrap their head & grab their face, (5) you begin to simulate a series of rakes, rips & gouges to their neck & face with your hands using a "face wiping" motion.

For the "face wiping" motion - which simulates both the initial palm strike and the subsequent rake of the fingernails across the opponent's face - our hand can be oriented in one of five basic ways:(1) Palm Striking Sideways from the Left, Then Raking Back Right-to-Left(2) Palm Striking Straight Up Under the Chin or Nose, Then Raking Down(3) Palm Striking Sideways from the Right, Then Raking Back Left-to-Right(4) Reaching Over the Opponent's Head (used if they're bent over), Then Raking Up(5) Wrapping the Opponent's Head, Then Raking From the Far SideThe rake of the fingers across the face also usually twists the opponent's neck, which helps to break their balance and forces them to turn.

An important part of the Shredder is getting behind your opponent, a position known as "chest-to-back". This is very effective because it drastically limits your opponent's ability to counterattack you. It's fairly easy to punch & grab someone standing right in front of you, but it's much more difficult to hit or grab someone behind you. Neck twists usually force the opponent to turn and give you their back, although wrestling moves like the "arm drag" and "duck under" can be used to get behind as well. The chest-to-back principle is shown in the following clip:Getting Chest-to-Back: http://www.youtube.co...Edited by Brian B. on Mar 29, 2012 8:52 AM

"closing" or "bridging the gap" - with a rapid flurry of strikes. For those familiar with Wing Chun or Jeet Kune Do (JKD), the technique was similar to the "straight blast" demonstrated in this clip:- Straight Blast Demo: http://www.youtube.co...

We trained this entry using the Muay Thai pads as the target, just like we train the jab/cross combo in kickboxing. However, we used a variation known as the "Palm Blast", where you hit with the palms of the hands rather than closed fists. This is better from a street self-defense perspective, since you avoid the risk of breaking your knuckles and you increase the likelihood of poking your opponent in the eyes with your fingers which will make them flinch. Once the students forced their opponent to back pedal with their palm blast, they wrapped their opponent's arm & got their other hand in the opponent's face, and then began to shred as before.

Once the students managed to successfully enter with the palm blast & start shredding, we practiced having the pad-holding partner try to get away by pushing on their shredding partner with the pads. This forced the shredding partner to stay close and continue to trap them by wrapping the head or arm so they couldn't disengage and recover enough to attack them back.

ENTERING WITH JKD HAND TRAPSOne common way that an opponent may try to prevent you from entering into close range is simply raising their arms to shield themselves from the palm blast and just push you away from them when you try to get close enough to shred. To deal with this, we practiced using two different JKD-style hand trapping entries to get past the opponent's raised arms. These entries were the same-side "slap hit" (known in JKD as a pak sao) and the cross-side "pull hit" (known in JKD as a lop sau). The goal was simply to knock the opponent's raised arm aside and simultaneously drive the other hand into their face, and then initiate the Shredder. (For an idea of how the JKD hand traps clear the opponent's forearms out of the way and create an opening for your initial strike, watch this clip: http://www.youtube.co...)

DEALING WITH ATTEMPTS TO DISENGAGEIn cases where the opponent was directly in front of you, we found it wasn't uncommon for the opponent to try to disengage by bending over at the waist. This allows you to put them in a position similar to a front headlock. However, the object should not be to simply headlock them and hold on. This wouldn't work against a larger, stronger adversary, and would leave you open to having your legs grabbed or (for men) being struck in the groin. Instead, you keep your hands in their face and continue to shred them. I demonstrated how you can use your hands to twist their head to the side & then pull up on their neck, which produces a powerful "neck crank" - known as a "front face lock" - that is very painful and can damage your opponent's cervical spine. (Here's a clip showing how to apply the front face lock: http://www.youtube.co...)

Another common way the pad-holding partner would try to disengage from the Shredder is by turning around and then bending over. If you're focused on keeping your hands in their face, you may accidentally end up hopping on the person's back. This would leave you vulnerable of being thrown to the ground. To prevent this, we found that it was often better to move back around to your partner's side so you could continue to keep your hands in their face. This way, you could still trap & shred them, often getting them in a position similar to a side headlock.

In addition to turning away or bending over, a very common way an opponent will try to stop your shredding is by grabbing your hands and pulling them off their face. The best way to counter this is to fingerlock them as soon as you see their hands come up, but BEFORE they grab your wrists. The best way to break a person's fingers is to only grab one or two of them, not three or four fingers and not the thumb. When you grab too many fingers they can resist having the fingers bent back, and the thumb is fairly strong and hard to break. Of course, sometimes you might not be able to get the fingerlock in time and the opponent will grab one or both of your wrists, controlling you and temporarily stopping the Shredder.

DEALING WITH THE DOUBLE WRIST GRABLastly, we covered how to use different "body weapons" (headbutt, knee, kick, bite) if an opponent grabs both your wrists, making them let go in order to (re-)initiate the Shredder. If you always assume you need your hands free to attack, you might freak out in a situation where someone grabbed both your wrists. But as I showed the students, you can make the opponent let go by kneeing or snap kicking their groin, stomp kicking their shin or instep, headbutting their face, biting their face/neck/shoulder, or biting into their fingers or wrist. Once your opponent lets go with at least one hand, you can then begin to rake, rip & gouge with it and flow into the Shredder.

CONCLUSIONThis seminar was a good introduction to the Shredder concept, and within a little over 90 minutes the students were all able to grasp the concept and apply it on a moderately resisting partner. I plan on running several more Shredder seminars over the summer, and I urge anyone interested to come and check them out. Each seminar will review the basics of how to employ the Shredder, but it will also introduce some new drills and it will cover some different scenarios like using the Shredder against an armed opponent, against multiple opponents, or while wrestling on the ground. This means that it's still useful to attend another Shredder seminar even if you've been to one of them already.

NOTE: I'm not certified by nor affiliated with the Shredder's creator, Richard Dimitri, although I've attended one of his training seminars, participated for several years on his online forum (http://senshido.savi...., and own several of his instructional DVDs. He's a great instructor and his materials are top notch. If you're interested in learning more, I can definitely recommend purchasing any of his DVDS - especially the Shredder Package: http://www.senshido.c...Edited by Brian B. on Mar 29, 2012 9:07 AM
