The ZAP Blast Knuckles Extreme fits over your fingers like a knuckle grip and puts 950,000 volts directly in your fist. Four spiked electrodes do two things at once: they deliver the stun charge and provide physical stopping power if you need to strike without activating the electrical system. The rubberized contour grip keeps it secure whether your hands are dry or not.

  • 950,000 volts and 5 milliamps through four spiked electrodes positioned at the knuckles
  • Knuckle-grip design keeps the device secured to your hand during a confrontation
  • Rubberized ABS plastic contour grip for reliable hold in varied conditions
  • Safety switch prevents accidental discharge; intimidating profile provides visual deterrence
  • Includes nylon holster; powered by 2 CR123A lithium batteries; 2-year warranty

Stun Protection That Stays in Your Hand When You Need It

Most stun guns require you to hold the device precisely and make clean contact to be effective. The Blast Knuckles Extreme removes that variable by securing itself around your fingers. Once it’s on, it’s not going anywhere. The four spiked electrodes at the knuckle line deliver 950,000 volts on contact — and the spikes themselves add a mechanical deterrent that doesn’t require battery power at all.

This design makes particular sense for situations where you’re already moving — jogging, walking a trail, navigating a parking structure at night. Your hand is already in a functional position. The device is already accessible. You’re not reaching for anything.

Who This Stun Gun Is For

The Blast Knuckles Extreme suits people who want a stun gun they can keep in hand during higher-risk activities — running alone, walking to a car late at night, or moving through unfamiliar areas. It works well for anyone who finds palm-held stun guns awkward to grip under stress, since the knuckle design doesn’t rely on grip strength to stay in place.

It’s also a practical option for people who want multiple response levels in a single device. The spikes provide a deterrent and a physical strike option independent of the electrical system — useful if batteries run low or if visual deterrence alone resolves a situation before it escalates.

Is This the Right Choice for You?

Choose the Blast Knuckles Extreme if you want:

  • A stun device that stays secured to your hand during movement or a struggle
  • Physical striking capability independent of the electrical system
  • A compact option suitable for jogging, trail walking, or active carry
  • 5mA output in a device that fits in a jacket pocket or holster

Consider something else if you need:

  • A built-in rechargeable battery — this uses CR123A disposable cells
  • A low-profile device that doesn’t draw attention — the spiked design is visible and intentionally assertive

How the Blast Knuckles Extreme Works

The device fits over four fingers with an open-frame grip, positioning the electrode spikes across the knuckle line. When the safety switch is disengaged and the trigger is pressed, 950,000 volts arc between the electrodes. Contact with an attacker’s body disrupts muscle control, which typically incapacitates for several minutes without permanent injury.

The four spikes serve a secondary function: they create surface contact points that improve electrode-to-target connection. They also mean that a closed-fist strike delivers meaningful physical impact even without the electrical charge — a useful backup if you’re in a protracted situation and need options.

The rubberized ABS plastic body keeps the device from shifting in your hand. The safety switch is positioned for quick one-handed disengagement. Two CR123A lithium batteries power the system and are widely available at hardware and camera stores.

Frequently Asked Questions

How do the spikes work — are they sharp enough to cause injury?

The four electrodes are designed as spikes to improve contact and add deterrent value, not to cause serious lacerations. They’re firm and pointed enough to make meaningful contact during a strike, but the primary function remains the electrical stun output. Think of them as a functional design element that improves electrode contact and adds physical impact, not a bladed weapon. The spikes also have the secondary effect of potentially collecting surface material — including DNA — which can be relevant if a situation leads to a police report.

Will the Blast Knuckles Extreme fit most hand sizes?

The open knuckle frame accommodates a broad range of hand sizes. Most adult hands — from smaller women’s to larger men’s — fit comfortably. The device doesn’t need to fit perfectly; it needs to stay in place during use, which the frame design ensures. If you have very small hands, the grip may feel slightly loose, but it will still function as intended.

Are CR123A batteries easy to find?

Yes. CR123A lithium batteries are standard and available at hardware stores, camera shops, grocery chains, and online retailers. They have a long shelf life — often 10+ years in storage — and hold voltage consistently until they’re nearly depleted, which makes them reliable for a device you may not use frequently. Keep a spare set on hand and replace them annually as a general practice.

Can I carry this while jogging without it activating accidentally?

Yes. The safety switch must be manually disengaged before the trigger will activate the stun circuit. With the safety on, the device can be gripped, bounced, or jostled without risk of discharge. Many users carry it in-hand with the safety engaged during their run and disengage only if they perceive a threat — which takes a fraction of a second.
