These fit over your knuckles like a set of brass knuckles — except instead of just impact, you’ve got 950,000 volts ready to go. Four spiked electrodes, rubberized grip, and it rides in the palm of your hand. Good for runners or anyone who wants something that’s hard to drop and ready fast.

  • 950,000 volts / 5 milliamps — significant stun output in a palm-held design
  • Four spiked electrodes — provide a physical deterrent on their own if needed
  • Rubberized contour grip — fits the hand securely, harder to knock away
  • Compact dimensions — 4.4″ x 1.13″ x 3.25″, sits in your fist without bulk
  • Nylon holster included — clip it to a belt or bag when not in use

Fits Your Hand, Stays in Your Hand

The design here is the main thing — it goes over your knuckles, so your grip on it is your grip on your hand. That’s different from a standard stun gun where someone can knock it out of your palm. The rubberized contour fit means it sits snugly without squeezing. If you’re a runner who wants something you can carry in your fist for a few miles without fatigue, this makes sense.

The four spiked electrodes around the contact points add a physical deterrent element. Even without activating the stun function, the profile is enough to make most people think twice. And if the batteries ever run low, the spiked frame still provides an impact option. Runs on two CR123A lithium batteries — easy to find, long shelf life.

Who This Stun Gun Is For

Runners and joggers are the obvious fit — it’s specifically designed to be carried in the hand for extended periods without fumbling. But it also works well for anyone who wants something immediately accessible without reaching into a bag or unsnapping a holster.

The knuckle-grip design also suits people with smaller hands who find standard stun guns awkward to hold securely. The contoured fit gives better purchase than a flat or cylindrical device.

Is This the Right Choice for You?

Choose the Blast Knuckles Extreme if you want:

  • A stun gun that stays in your grip — hard to drop or have knocked away
  • Something designed for active carry — running, walking, hiking
  • A physical deterrent from the spiked design even without the stun feature
  • Immediate access — no holster draw, no button hunt, it’s already in your hand

Consider something else if you need:

  • Rechargeable convenience — this runs on CR123A batteries, not USB
  • A concealed pocket carry — the knuckle design isn’t as discreet as a flat stun gun

How the Design Translates to Practical Use

Standard stun guns work fine when you have time to reach for them. The Blast Knuckles are for situations where you’re already moving — running, walking fast, hands already active. Because it wraps around your fingers, it’s part of your natural hand position rather than an object you’re gripping. That means less fumbling when things get tense.

The 5 milliamp output is solid. Voltage grabs attention; milliamps are what cause the muscular disruption. At 5 milliamps, a contact will cause significant involuntary muscle response. The spiked electrode design around the contacts also means the contact points stay consistent against uneven surfaces — you don’t have to worry about getting a clean flat press.

The nylon holster lets you clip it to a belt or bag strap when you’re not actively carrying it in-hand. Safety switch prevents accidental discharge. The ABS plastic body with rubberized coating handles drops and outdoor use without issue.

Frequently Asked Questions

How do you hold it — does it fit most hand sizes?

It’s designed to fit over four fingers like a set of brass knuckles. The rubberized contour grip accommodates most adult hand sizes reasonably well, though people with very large hands may find it a snug fit. The design prioritizes security over adjustability — the goal is that it won’t come loose during movement. If you’re between sizes, it’s worth handling one in person if you can, or checking the return policy before ordering.

What are CR123A batteries and where do you get them?

CR123A are 3-volt lithium batteries — the same type used in many flashlights, camera equipment, and tactical gear. They’re not AA or AAA, but they’re widely available at hardware stores, electronics stores, and online. They have a very long shelf life compared to alkaline batteries, so you’re not swapping them out often. The tradeoff vs. rechargeable is convenience for some people — no cord needed, just keep a spare set around.

Is the spiked design legal to carry?

Stun gun laws vary by state and locality, and some jurisdictions have specific rules about spiked or knuckle-style devices that may go beyond standard stun gun regulations. Most states that permit stun guns don’t specifically prohibit this design, but it’s worth checking your local laws before purchasing. The spikes are part of the electrode design, not ornamental — they improve contact surface consistency. As always, carry legally and responsibly.

Can you run with this in your hand without it being uncomfortable?

That’s kind of the whole point of the design. The knuckle mount means you’re not clenching a device — it’s part of your natural hand position. Runners who’ve used knuckle-style carry devices (like running weights or knuckle flashlights) will recognize the concept. The rubberized grip handles sweat and movement without slipping. Most people find they can carry it for a full run without thinking about it much.
