The Defender: A Covert Defensive Tool



Don’t let the small size fool you; this lit­tle tool can help you out of a jam!

I recently had the oppor­tu­nity to learn how to effec­tively use this device at a train­ing con­fer­ence I was teach­ing at and now I am in the process of becom­ing a cer­ti­fied instruc­tor in the use of it. I plan on teach­ing my police offi­cers and mar­tial arts stu­dents how to use this strange look­ing object to defend them­selves, and in the case of my fel­low police offi­cers, to con­trol the bad guy so that he can go to jail!

What is it? That is what peo­ple will prob­a­bly ask you when they first see the Defender. That is actu­ally an appro­pri­ate ques­tion because at first glance it looks like a cross between a bot­tle opener and a wind­shield scraper (for those who know what that is Hint: you have to live where it snows).

Check out the video below to see it in action

Mas­ter Peter Brusso has quite an inter­est­ing back­ground. He is a Viet Nam Era vet­eran. He is an engi­neer. He is a pri­vate pilot, but the most impor­tant thing is he is a true war­rior. With black belts in many mar­tial arts, real life com­bat expe­ri­ence, and years and years of mar­tial arts teach­ing experience.

Fur­ther­more, his work in the mil­i­tary actu­ally inspired a book which then inspired the movie “The Men Who Stared at Goats.” With all of that said, and given Mas­ter Brusso’s expe­ri­ence fight­ing in the Cam­bo­dian jun­gles and his other real world com­bat expe­ri­ence, in addi­tion to hav­ing an engi­neer­ing degree, he is the per­fect man to invent a rather inno­cent look­ing covert defen­sive device.

The Defender is a piece of plas­tic type mate­r­ial flat but with a unique shape. The edges and sides of the Defender all have spe­cific pur­poses. You can con­trol a per­son with one side, apply pres­sure to vital tar­gets with another side, and strike with many of the sides. The Defender is designed as a less-lethal device; how­ever, if your life was in jeop­ardy you could use it in a more dam­ag­ing man­ner than how it would nor­mally be used.

Unlike other more omi­nous and sin­is­ter look­ing self-defense weapons that would be banned from cer­tain loca­tions, this device, or tool as Mas­ter Brusso refers to it, is quite inno­cent look­ing and will fit into your back pocket or purse. It might not replace hav­ing a firearm when some­one is shoot­ing at you, but in close quar­ters com­bat sce­nar­ios this device could be exactly what you need to defend your­self and live.

I was famil­iar with Mas­ter Brusso and some of his train­ing prod­ucts because I had pur­chased the com­bat Machete video a while ago. I was very impressed with that video and learned quite a bit from it. More­over, it was one of the only, if not the only, video avail­able explain­ing how to use and defend against the machete. Machetes are car­ried all over the world and they are cer­tainly a com­mon tool found where I work as a police offi­cer, South Florida. Look for future arti­cles about other Mas­ter Brusso videos and train­ing courses; he has pro­duced many qual­ity prod­ucts which I am in the process of reviewing.

So for now, Happy New Year! Stay Safe and Always Remem­ber, “If Not Me, Then Who?”

    The Defender looks interesting. BUT….if a kubotan is illegal to carry in NJ, how would the defender not be perceived as illegal too? Thanks.

    I probably missed it, but did you say were to buy this at? I googled it, but couldn’t find it. How do I get one?

    I still find it hard to prepare to protect myself by using something that allows an attacker to get so close to me or mine. I will give up my gun when I’m out of bullets and then switch to a knife most likely. Digging the bag of assorted Defenders out and then choosing the one I need for the situation presented, may not be the fastest.

    Buy two 8 oz cannonball sinkers. They have a wire loop imbedded in the lead. Tie 20-24″ of para-cord to the sinkers one on each end. This will leave about 16-18″ of distance between these two sinkers. Hold one of the sinkers firmly in one hand with the cord projecting between your ring and middle finger. The second sinker can then easily be swung against a target (hand, shoulder, elbow, head, dog other animal, etc.). The lead tends not to bounce back on the person swinging.

    These will work really well on an adversary who is impaired enough to stand still while you use the tool.

      You can use this on a moving attacker. You hold it in your hand and perform blocks and strikes with it to amplify your power and the damage to the attacker.

    Just like with any defensive tool you need to train with them and know what they are capable of. These tool are for pressure points and nerve motor point strikes. Study the strike points of the human anatomy and you will see just how effective defensive tools like these can be.
