I wanted to like it
The knife is extremely hard to open, the way you have to push on the thumbstud to open it can make your thumb almost get caught by the blade as it swings out when the "assist" kicks in. The pocket clip is loose even with the screws tightened all the way, the screw heads on the scales strip out extremely easily, I have paid $30 for better quality knives than this one. The quality of this knife is on par with the smith and wesson border patrol knife that I bought at least 7 years ago that I stuffed in a drawer somewhere because of how much it annoyed me. I can't believe retail for this knife is over $40... And tbh, anyone that paid the $129 msrp on this knife got royally screwed. The only thing I liked about it was the shape of the cutting portion of the blade. I do believe the blade could be useful, but there are some serious issues with this knife.

Pros: Blade Material, Overall Quality, Ease of Opening, Handle Feel, Pocket Clip
Cons: None
To be honest I was a little hesitant to order it after reading some of the reviews, but now after receiving the knife I don’t know what they were talking about. Maybe they fixed the problem or mine is a special case but mine opens great smooth action and locks open hard. The blade steel is great quality and comes with a good edge on it. But especially at this reduced price I might buy a couple and I highly recommend it to anyone considering this knife pull the trigger it’s totally worth it.

Great knife for its price!
This isn't the best knife in the world, obviously, but I read these reviews where people complain about its quality and about how difficult it is to open... It costs less than $40, for S30v steel! And it has assisted opening. What more can you wish for without paying hundreds of dollars for it?!It's not easy to open single-handed but it is possible, I found that loosening the screws and adding a bit of oil makes it easy to open. Other than that I'm very happy with its robust build and a large blade. The blade is very sharp out of the box and the knife itself is of fairly high quality! I have ZERO complaints, if you factor in the amazing price of this knife.
