Looks like a hairbrush. Works as a self-defense tool. The brush is fully functional — it’s not a prop — and the 4.25-inch ABS plastic blade is concealed inside until you need it. It’s one of those things that I found genuinely clever the first time I saw it: something you’d already carry without a second thought.
The idea here is straightforward: a hairbrush is something most people already carry and nobody looks at twice. This one separates into two pieces — the brush stays a brush, and the handle reveals a rigid 4.25-inch ABS plastic blade. When it’s assembled, there’s nothing to indicate it’s anything other than a basic grooming item.
It’s a niche product, but the niche it fills is real: situations where discretion in carry matters and you’d rather not have something that looks obviously like a weapon sitting in your bag.
If you’re someone who carries a bag or purse daily and you want a defensive option that stays genuinely low-profile, this is worth considering. It’s designed to sit in a bag alongside your actual everyday items without standing out. People who work in environments where openly carrying a traditional knife isn’t practical — nightlife, travel, certain workplaces — tend to find the design concept useful.
It’s also one of the more affordable self-defense options available, which makes it an easy add-alongside-something-else purchase rather than a significant decision. Available in black, pink, and purple.

Consider something else if you need:
The brush and handle separate cleanly to reveal the blade. The ABS plastic construction is rigid and impact-resistant — it’s designed to deliver focused defensive force rather than to cut. If you’re expecting a traditional knife edge, this isn’t that. Think of it more as a rigid defensive implement that happens to be shaped like a blade.
The included glass breaker/skull crusher adds a secondary option at the end of the handle — useful context if you’re thinking about vehicle emergencies or close-quarters situations where you need to break a window. The overall 6.25-inch length gives you enough handle to grip the tool securely.
The brush side is genuinely functional — it’s not a prop. That’s the detail that makes the disguise work in practice, since a brush you never use would look odd sitting in your bag over time.

Important: Check your local laws regarding disguised knives before purchasing. Regulations vary significantly by state and municipality.
If discreet carry is the priority and you want something that doesn’t announce itself as a defensive tool, the brush knife covers that ground in a way that very few other products do.
The blade is ABS plastic, so it’s rigid and impact-resistant rather than sharp-edged like a steel knife. It’s designed to deliver concentrated defensive force — jabbing or striking — rather than cutting. If you’re looking for a product with a cutting edge, a traditional steel folding knife would be a better fit. The brush knife’s strength is in its disguise and its rigid construction.
Laws around disguised weapons vary quite a bit by location. Some states and cities have specific restrictions on concealed or disguised knives regardless of material. It’s worth spending a few minutes looking up your state and local regulations before purchasing. This is true of any edged self-defense tool, but especially worth checking with a disguised design.
Yes — the brush component is fully functional, not decorative. The bristles are real and the brush works as advertised. This is actually important to the design: a non-functional brush would look out of place in daily use, defeating the purpose of the disguise over time.
The glass breaker/skull crusher is a hardened point built into the handle end of the tool. It’s designed to break tempered glass — like a car window — in an emergency situation where you need to exit a vehicle quickly. It doubles as a striking point for defensive use. It’s a secondary feature, but a useful one to have available.
