Plastic Brush Knife – Disguised 4-Inch Blade, 6.25″

There are moments when looking like you’re carrying nothing at all is part of the plan. This 6.25-inch hair brush holds a 4-inch ABS blade out of plain sight, and the Plastic Brush Knife does it without drawing a second glance. If discretion matters to you, that’s exactly the point.

Who This Knife Is For

This is a fit for someone who wants a backup option that doesn’t advertise itself. College students, commuters, and travelers who prefer to keep their carry low-profile will find it practical. It’s also a reasonable choice for someone who wants a compact emergency tool — the glass breaker tip adds a layer of usefulness in situations like a vehicle entrapment where seconds matter.

Care and What’s Included

What’s in the Box

• Plastic Brush Knife (brush body with concealed blade)
• Glass breaker / skull crusher tip (included as part of the unit)

Care

ABS plastic is low maintenance. Wipe it down with a dry or slightly damp cloth. Keep the blade clean and dry. Don’t expose it to prolonged heat — like a closed car in summer — which can warp plastic components over time.

Legal Notes

Knife laws vary widely by state, city, and venue. Blade length limits, concealed carry rules, and restrictions on disguised weapons differ depending on where you live and where you carry. Check your local laws before buying or carrying the Plastic Brush Knife. When in doubt, check with a local attorney or your city’s ordinance database.

Plastic Brush Knife: Frequently Asked Questions

What is the blade length on the Plastic Brush Knife?

The blade is 4 inches long. The overall unit — handle included — measures 6.25 inches. Both the blade and handle are made from ABS plastic, which keeps the whole thing lightweight and consistent. It’s a compact size that fits easily in a bag or on a shelf without drawing attention.

Is the Plastic Brush Knife a real brush?

The exterior is designed to look like a hair brush. The focus is on concealment, not brushing hair. Think of it as a disguised carry tool first. The brush appearance is what makes it discreet — that’s the whole idea behind the design.

What does the glass breaker tip do?

The glass breaker, sometimes called a skull crusher tip, is designed to shatter a car window in an emergency — for example, if you’re trapped in a vehicle. It’s a secondary safety feature built into the same unit. No extra tool needed; it’s already part of the package.

Is the Plastic Brush Knife legal to carry?

Knife laws — especially for disguised or concealed blades — vary significantly by state and city. Some areas restrict blade length; others have specific rules about disguised weapons. Before you carry this knife anywhere, check the laws where you live and anywhere you plan to travel. Don’t assume what’s legal in one state applies everywhere.
