major flaw Reviewed by on Jul 27, 2016   5 out of 5

Upon receipt of my brush knife, we discovered a major flaw. The brush became the absolute favorite grooming device of my cat! This cat HATES being brushed, and as soon as I took this out of the box, she jumped in my lap and let me brush her with it for an hour! Now I have to buy another one for my wife!

For All Family Members Reviewed by sfldogs on May 20, 2015   5 out of 5

Simply put, I bought one for each of my Family Members. It should be understood, that these are for the Jabbing hand. Practice; with these as a Jab Extension for Defense; with the blade in direction of the pinky.

awesome designer accessory!

self defence Reviewed by Tom on Jan 19, 2015   4 out of 5

This is an emergency self defence weapon, not a daily use knife. As such, it has good potential in an emergency. To the people who want a sharp blade, not happening in plastic. Carry a steel blade for that.

Very nice Reviewed by Dan on Jun 27, 2013   5 out of 5

The product is very nice. It is strong and will do what it was purchased for. I purchased two. One for my wife and one for my daughter. I purchases them for there self defense. People saying the brush is a joke of not good to use are being stupid. If you want a brush then buy a brush. If you want something that will protect your loved ones then. Buy this product.

Pretty slick Reviewed by Jef on Jun 22, 2013   4 out of 5

Got this for my wife. She digs it. Since it's all plastic, it doesn't set off ANY metal detectors and looks like a brush going thru an xray. It's also cheap enough, that if it DID get confiscated after a scan, you aren't losing much. Only con is that the head does come off a bit easy when she's brushing her hair, but I put some black electrical tape around the bottom and put the head back on and it snugged it. Can still pull it off with ease, it just doesn't slide off so easily while in use. Good price, good point, good product. I recommend.

Ok Reviewed by Brad on Apr 08, 2013   3 out of 5

I bought this for my wife, and she told me that the brush is a joke. She said that no woman would ever brush her hair with it. The dagger is decent though. The tip bent to the side while stabbing a plastic container, so I just shaved down a bit, but I'm convinced that if used to stab into soft tissue that it would penetrate just fine. It would be more useful if it was bladed as well, so that way you could slash as well as stab. I would recommend carrying a knife instead of this. The idea is good, but it could've been done a lot better.
