Brush Knife – 4-Inch ABS Blade with Glass Breaker Tip

Most people never think twice about a hair brush sitting in a bag. That’s exactly the kind of everyday invisibility that can work in your favor — and it’s the whole idea behind the Brush Knife, a 6.25-inch hair brush that conceals a 4-inch ABS blade and a glass breaker tip without looking like anything other than something you’d use before a meeting.

Who This Stealthy Carry Option Is For

This one’s for the college student walking back to her dorm at 11 p.m., the retail worker closing up shop alone, the traveler who wants something discreet in a carry-on bag or glove box. It’s for anyone who wants a quiet edge without the conversation that comes with a visible folding knife. If you’ve been told you can’t carry at work, or you just don’t want the attention, this is built for you.

Is It the Right Fit for You?

Choose It If You Want

• Something that blends into a purse, backpack, or travel bag without raising eyebrows
• A no-battery, no-charging self-defense option that’s always ready
• A glass breaker tip on hand for vehicle emergencies
• A budget-friendly everyday carry tool under $10

Consider Another Option If You Need

• A longer reach — an expandable baton gives you distance
• A non-contact deterrent — a personal alarm or pepper spray doesn’t require close contact
• A heavier-duty cutting tool for utility tasks beyond self-defense

Brush Knife: Frequently Asked Questions

What is the blade length on the Brush Knife?

The Brush Knife has a 4-inch ABS plastic blade. The overall length of the unit — brush and blade together — is 6.25 inches. That’s compact enough for a small purse pocket while still giving you a usable blade when you need it.

Does the Brush Knife work as a real hair brush?

It does. The bristles are functional — this isn’t just a shell shaped like a brush. That’s what makes the disguise effective. It looks right at home in any bag because it actually belongs there. Nobody questions a hair brush.

How do I access the blade quickly under stress?

Practice is everything here. The blade is concealed by design, which means accessing it fast takes muscle memory. Before you rely on it, rehearse drawing the blade from the brush several times so the motion is automatic. A tool you can’t get to quickly isn’t doing you any favors.

Is the Brush Knife legal to carry where I live?

Laws on disguised blades vary widely by state, county, and city, and they change. In many places they’re perfectly legal, but some jurisdictions restrict concealed blades or have blade-length limits. Check your local laws before you carry — especially if you’re traveling or entering campuses, government buildings, or other restricted locations.
