These are a different kind of stun gun. The Blast Knuckles fit over your fingers like a set of brass knuckles, so you're not fumbling for a grip under pressure — you've already got one. Four spiked electrodes up front mean even if you never fire the stun feature, they're doing a job on their own.

  • 950,000 volts with 5 milliamp output — serious stopping power in a knuckle-mounted form factor
  • Four spiked electrodes that work as a contact weapon independent of the stun function
  • Rubberized contour grip keeps it secure in your hand when things get physical
  • Runs on 2 CR123A lithium batteries — widely available, long shelf life
  • 2-year warranty from ZAP, nylon holster included

A Stun Gun That Fits Like a Weapon Should

The idea behind the Blast Knuckles is pretty straightforward: most stun guns require you to hold something, aim, and make contact. The knuckle design skips the fumbling part. You slip it on, and your whole fist becomes the contact point. For someone who spends time walking alone at night or jogging in areas they’re not totally sure about, that kind of fast-access design has real practical value.

The spiked electrodes aren’t just decorative either. Four sharp points up front mean the unit functions as a contact weapon even with dead batteries. That’s a decent backup to have.

Who This Stun Gun Is For

Joggers and dog walkers are the obvious fit here. You don’t want to be digging through a pocket or bag — the Blast Knuckles stay on your hand and ready the whole time you’re out. It’s also a reasonable option for anyone who’s tried a standard stun gun and found the grip awkward under pressure.

People who want a backup striking capability alongside their stun function will appreciate the spiked design. It’s not subtle, and that’s part of the point — the intimidation factor of the look is real, and it works in your favor before anything else has to happen.

That said, it’s a purpose-built tool. It’s not something you’d slip into a jacket pocket and forget about. It’s designed to be on your hand, used actively.

Is This the Right Choice for You?

Choose the Blast Knuckles Extreme if you want:

  • A stun gun that stays in your grip without fumbling
  • A dual-function tool that works as a contact weapon even without power
  • A deterrent with visible presence — the spiked design communicates clearly

Consider something else if you need:

  • Discreet everyday carry — this one is visible and intentional, not subtle
  • Something that fits in a pocket or bag without thought

How It Actually Works

The Blast Knuckles fit over your fingers and sit against the back of your hand. The four electrodes face forward, and when the stun is activated, any contact those spikes make completes the circuit. You’re not trying to press a small contact point to someone’s arm — the geometry of the grip does the positioning for you.

The rubberized contour grip is one of the things I’d call out specifically. Sweat, rain, adrenaline — none of that changes your hold on it because your fingers are locked in. That’s a real-world advantage that a smooth plastic housing doesn’t give you.

950,000 volts at 5 milliamps is enough to cause involuntary muscle disruption and significant pain. The spiked electrodes, as a secondary function, are capable of drawing blood on contact — which the manufacturer notes can be useful for DNA collection if there’s ever a need to involve law enforcement afterward. Practical detail worth knowing.

Frequently Asked Questions

How do the Blast Knuckles fit on your hand?

They slip over your fingers similar to a set of brass knuckles, with your fingers passing through two loops and the unit resting across the back of your knuckles. The rubberized grip keeps it from shifting. Most people find the fit secure without feeling restricting — you can still move your hand normally while wearing it.

What are the CR123A batteries, and where do you get them?

CR123A lithium batteries are a standard size used in high-drain devices like cameras and tactical flashlights. You can find them at hardware stores, camera shops, sporting goods stores, and online. They have a long shelf life and hold their charge well in storage, which makes them practical for a device you’re not using every day.

Can you use this as a striking weapon if the batteries die?

Yes. The four spiked electrodes on the front face are solid and designed to make contact as part of a punch. They don’t require power to function as a physical contact point. The knuckle mount also reinforces your grip during impact, similar to how brass knuckles function mechanically. It’s a legitimate backup if the stun component isn’t available.

Is the Blast Knuckles legal everywhere?

Stun gun laws vary by state and municipality, so it’s worth checking your local regulations before purchasing. Some states restrict stun guns entirely, and a few others have specific rules about the type or design. The knuckle design may fall under additional restrictions in some jurisdictions. Check your local laws — it’s a five-minute search and worth doing.
