Review: For the price you just can’t beat it. It’s a sturdy well made knife. It is a little heavy because it’s built to be sturdy but love the spring assisted opening. Opens smoothly and quick if you are doing it correctly. For $8 I wasnt expecting near the quality of this knife that it turned out to be. And yes it is very sharp. Great knife all around

## Questions & Answers

**Q: I just got this knife.  Opened it twice, and on the second open, it's now stuck open.  How do I close it?**
A: I had a similar problem. If you don't know how to unlock it, simply look at the knife handle with blade facing you, and look near the guard. Under it should be a curved piece of metal inside the hollow area of the grip. Push that with your thumb to the left. That doesn't. Work, try right. When I first got it it was hard to close too. Just push with more force and it'll give way. It also eventually gets much easier. Thanks for asking! If you find no solution, contact the company, who's name is Mtech. Hope this helped!

**Q: Is this considered a gravity knife?**
A: Yes it's a great knife use it everyday

**Q: is the window punch, spring loaded?**
A: The window punch is actually as small pice of aluminum built into the butt of the knife and is stationary (not spring loaded), about 4/10ths c wide by 4/10ths cm high. If you use the zoom feature on by hovering over the picture of the knife you can see it. Though I haven't had to use the window breaker yet, I would suggest on buying a tool built for breaking a window. Also the blade is not spring assisted as the description would say but thumb assist. Use your thumb to press down on a stationary leaver and flick your wrist to open, the downward force of your thumb and momentum of your wrist open the blade and snap it in place.

**Q: no instructions in box. how do i close it?  ordered 2 another on the way**
A: Once the knife is opened there is a little metal tab you push to the side and you just fold the blade back in
