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

Solid, all metal build, excellent quality control. Unbelievably good buy. All screws snug. Blade sharp, quick to deploy with spring assist, easy to close. Better quality build than many higher priced edcs. Heartily recommended as perhaps the best buy on Amazon.

Heavy!... Solid knife ...good flip action and closes easy....not a knife to carry all day in your pocket or on your pants....but worth the money for anything else.... Crazy sharp.... careful it's razor like!... I like it!

As good as any mid priced folder. Quality as good as cold steel. With the handle shape and glass breaker can be used as a striking weapon even closed. Opens easily added a drop of oil to the pivot. Good handle weight without being too heavy. Came sharp, not super sharp but about five strokes on a ceramic rod and it was scary sharp , able to shave arm hair. I can't believe I only paid 8 bucks for this. Bought two more for a total of four. I have a big knife collection and carry one or two daily. This will be carried often. Some knife snobs might not like it but I rate my knives on their abilities. This is a keeper!

Excellent knife especially for the price. I got this as a “do everything” tool for garage/household. In that respect, it is fantastic. It’s built very well and no part of this knife is flimsy. The action is a little stiff that get better, but not by much so your finger will do a lot of the work. Blade seems to hold edge sufficiently and considering what I’ve used it to cut, it’s probably done better than most. It is very heavy though. You certainly know that you’re holding it so don’t intend for it to be sliding around anywhere because it’s like a little brick. I like that- but just a heads up. So for price and build quality definitely five stars.
