Question: how to close the knife?
Document: This Product Was Really Great When it came in the mail , the only thing was that i had no idea on how to close it because the instructions it came with on how to close it wasn't for the type of knife that i ordered but then eventually i got it to close and i was happy with my product
I needed to replace my folding knife and this one not only fell well into my price range, but it also was designed with the features that I was looking for.Easy to open, easy to close, sharp and lightweight.Very happy with this investment.
Very happy with this purchase!The weight of this knife is very well balanced. The rubber handle feels very secure in your hand, when you clip it onto your belt or pants it's very secure and best of all it's extremely sharp. Easy open, easy close. If you plan on getting a knife, this is the one to get.
The blade doesn't close properly. It hits the inside of the metal. It more than likely just needs an adjustment but it has already removed the paint from the side of the blade. I should have paid a couple extra bucks and got the Black Ops knife. My friend has on and for a 10$ difference it's like night and day.
Good  knife for little money. Sturdy, fits well in the hand, i like the cutter on the other end. It actually took me a few minutes to figure out how to close it. I'm laughing about that now though. The instructions are printed so small that i couldn't even read them - i couldn't understand why you would need instructions anyway!
I bought this knife for me I am a 57 year old, and I carry it for many reasons. The end has a blade I would use for cutting the seat belt if I ever need to use one. It is sharp and easy to open and close. I carry it in my Coach purse everywhere I go.
Screw came undone within 2 weeks of use. Then the screw could not even be screwed back it. It actually stripped itself. I know it sounds weird but I did nothing to the knife besides open it, close it, and opened some packages with it. Did nothing unusual or crazy with it. Wasn't as sharp as I would like either. There are better knives in the relatively same price range on amazon.
But that can probably be remedied by loosening the torque screw a little, but it's not really bad. Kind of a cool looking knife but I doubt that it will hold up to much heavy use. To keep in your back pack as an extra, uhhhh, I don't think you could rely on it. Sooo, if I lost it, I wouldn't care. It's not total junk, but pretty close. But hey, it was only 20 bucks! What do you want! ?
I'm very happy with my purchase. The knife fits well in my hand and is easy to open/close one-handed. The blade is very sharp, and the serrated section of the blade is great for sawing. Hope I never have to use the seatbelt cutter or the glass breaker, but I'm sure that they work excellently as well!EDIT: This product is so exceptional that it was stolen from me and I'm ordering a new one to replace it. Cheers!
I ordered this knife a couple of months ago and it has become the knife I carry each day. I like the look and feel of the knife. The only complaint I would have is that it doesn't make that distinctive "click" sound to let you know it is locked in the open or closed position. There have been a few times I've thought it was locked and it wasn't. I just double check each time now that I open or close instead of assuming.
Answer: yes
