Damn Suprised

I got this knife not thinking much of it because of the price....that was my 1st mistake... 🤔 Thinking!! Anywho, this is a BEEFY, HEFTY, CUT THROUGH BONE BLADE!!!! It feels like what a man expects to feel/weigh when he picks it up!!! The weight blew me away!! Makes a razor blade seem dull!! NO PLAY in the blade/body connection and the ball barring makes it seem spring assisted!! I been beating the hack outta mine, and it's yet to say uncle!!! Get it!!! You WILL NOT, N O T BE SORRY!!!🤘 Just an update I know it's been less than 2 weeks but it's few and way too far between when you get a product that not to surpasses your expectations but straight sets a new standard to your expectations paradigm of a blade that'll just kick some a** and then kick some more and then when you think it's all kicked out it's ready to kick more!! I've had Esse's, Falknivven, Cold Steal, Bucks, Benchmde, CRKT, Ned Foss, Mora's, Gerbers and some off brands made out of Damascus that were fair to midland.....but kust the blade's girth, HEFT, quality, staying razor razor sharp with only crossing a steel here and there...i call it my EDK (Everyday Killer) insteada my EDC.....though that's what its has become!! The next joke about the guy that brought the knife to the gunfight that guy should have brought this knife bullets will bounce off this blade!! FRFR!! I don't think I was this happy and problem my kids are born! LOL in case they read this of course I was guys! But for less than $30 I mean I feel like I should send them 30 more and I bet you will too this is the deal and steel of shoot since I can remember again you will be so surprised and you will thank yourself! I just ordered two more.... Just for me!!! D O I T!!!!!

Wicked knife

I’m amazed at how good this knife looks and the fact that it came very sharp right out of the box. This is one more hefty knife. Flipper is incredibly good as it seems to be a bit oversized. Lock up it tight and true. Feels good in my big hand. One warning to all who purchase this item. It screams attention. Be careful where you whip this out. It looks menacing. The steel is plenty tough but it comes sharp so I haven’t had to sharpen it yet.

Great knife

Now, this is a great knife. Full Size, may be too big for some... excellent action right out of the box, which is rare. And best of all, a BIG flipper tab, not one of those little stubby things that are just an afterthought. The big blade just flops right open, making it very easy to use. The serrations look very pro, identical to Spyderco, I guess they just copied that. The handle even seems to have very shallow finger grooves to improve grip. A definite keeper. The blade is stamped '440C' but whatever, for the price it's fine with me...

Stick with their fixed blade options

I bought the bighorn tactical clever and was very satisfied, so I grabbed this nighthawk folder. Didn't come very sharp. I need to put it on an electric grinding wheel to get it sharp. The other issue is the liner lock. If I flip it open too fast, the liner lock seems like it wants to go past the blade to the other side. The one good thing are the ergonomics of the grip. Feels great in the hand. Being under $30 no big deal, I'll probably end up giving it to someone I don't like.
