It's super convenient, we take our phones everywhere and having a protection device in your phone case makes it great for day-to-day use.
I was just traveling by myself, and having my self-defense phone case made me feel safer everywhere I went. I felt much more confident being alone and knowing I could protect myself if danger were to arise.

Dads with Daughters
As a veteran, lifelong martial artist, and
everyday carry guy, I know we’re our own first responders. But the reality is — depending on where you travel, what property you’re on, or even what state
you’re in - you can’t always carry the way you want to.
That’s why I’m so impressed with the Hammer Defense phone case. It’s legal, no moving parts, no metal — yet it’s strong enough to break wood or glass, and always ready in your hand. I carry it, I demo it, and I’ve ordered more for my family.

Getting back into martial arts with my daughters reminded me the world isn’t always as safe as we think. Since we’re always on our phones, the Hammer Defense phone case gives us one last line of defense if we ever need it.
As a dad of daughters in their early 20s, it makes me proud knowing they have the Hammer Defense phone case. Even though they take precautions, they’re always on their phones and this gives both them and me real peace of mind.

Mike, MMA Fighter
My name is Michael Mcdonough and as a former MMA fighter, I know my hands can get the job done. But when it comes to protecting my family and my friends and the people around me, I will absolutely use the Sharktooth Self Defense phone case. It goes right on your phone, no one knows you have it, and it puts power and precision behind every hammer strike.

This is the hammer defense phone case. I just used it. This thing is great. I normally don't like iPhones, but this makes me wish that I had one.

I am a Black Belt in the Kempo System of self defense. I've been doing self defense for 14 years now and I tell you, I don't go out without my phone case. I love to have it just there, ready anytime, anyplace, and anywhere
Self Defense Students
I was really interested in the phone case defense because unlike other weapons, I always have a phone in my hand, when I'm talking, when I'm looking at it. So it seems like a pretty useful tool for defending myself or enchanting my defense skills.
- Lily
I like that it is soft to hold, so you can actually just use it usually. But it's practical - BAM self defence.

I thought it was great. When I work in KEPL and walking around sometimes it's a little bit sketchy. So this seems like a good tool.

I love the simplicity of having it with me at all times! I work in Capitol Hill and sometimes it's a little bit sketchy so it's good to be prepared.
Andrea

This is really cool! I like that it's soft to hold so you can use it like a regular phone case, but it's practical so you can go BAM!
