Review: Great knife, high quality, very sharp - absolutely recommend!! - Excellent quality for this price point! It isn't too heavy and weighs about what you'd expect one to weigh. The grip os very comfortable. It is very easy to open, although it can be a bit hard to close (the locking mechanism is great!). It is very sharp and maintains its sharpness for quite a while. Design did not fade or anything, even after being exposed to sun, rain, snow, and dirt. I just bought my third knife because I keep forgetting to take it out of my backpack before I fly, so TSA generally takes it - it has passed through TSA with no issue a couple of times, though. I always come back to reorder this knife because of how much I love it! Absolutely recommend!
Review: Sharp looking yet very durable knife at a great price - This is a well made and sturdy knife. Lightning fast opening! Feels good in your hand. The finish is stylish yet this knife will get the job done every time. Great knife at a great price. Way to go M-Tech!

## Questions & Answers

**Q: Is this knife a good quality**
A: No. For the money, you can do better. The blade steel is said to be 440A, and it might be, but if so the heat treat is horrible because I've never been able to sharpen MTech's blades. I'd rather cheap knives be made of 420 because at least then, I'd be able to get them sharp. (They may not stay that way, but at least they'll be sharp for a little while. Their 440A blades come dull and they stay that way, so edge retention can be said to be excellent.) If you're on a super tight budget, get a Smith & Wesson folder; however, I'd recommend your getting a good knife, and Cold Steel makes some good budget knives and some fantastic mid- and upper-range knives. And regardless of the steel, their heat treat is spot on.

**Q: How do you close the knife?**
A: Turn the knife over. Look into the slot where the knife blade rests when closed. At the front of this slot there is a semi-circular notch and inside that notch is a serrated (sawtooth) arm that is holding the blade open. Push that sawtooth arm towards the belt clip. You may have to push the blade farther open to get the tension off that arm. It will move to the side and you can close the blade.

**Q: Is this knife legal in California?**
A: Plastic straws are illegal in CA.  I doubt u guys are allowed to carry sharp object's!

**Q: Is the lever sturdy enough for police work so I don't have to worry about it opening in my pocket?**
A: Yes, but personally I would not use it for anything of any official capacity. It does not open smoothly enough for me using the thumb switch and mine tends to stick sometimes. Now if you use the tab on the back it's better, but for police work, I'd get one that's more dependable and of better quality. Good utility or camping knife for the money though.

### ⭐⭐⭐⭐⭐ Best knife I had in a long time.
*by T***S on February 4, 2026*

I LOVE THESE KNIVES!! I got 2 and wear them in my bra under each arm. I highly recommend them for 2 reasons-They are bigger than average so that makes the grip easier and safer and the switch to open them is flawless. I've carried knives since I was 16 and I am 62 and was compelled to get these the minute I saw them and am so glad I did. Not a paid person y'all. I just really love them. I highly recommend everyone carry at least one on your body and one inside your vehicle and one to clip on your beds headboard above your head. Watch a few YouTube videos to practice 3 or 4 good moves and you will feel much safer. These would make a great Valentine's Day and Father's Day gift too. Men always need a knife in their vehicles too.
