What an awesome blade! Sheath sucks though
I love this thing! I've used it for everything from food prep to bushcraft and fishing. It holds an edge for a very long time and the handle is super comfortable. My only gripe is the sheath. For the price you pay, it should come with a belt loop or some way to carry it but it doesn't. Also, the little tab you have to press to unsheath the knife feels like it may break after a hundred uses or so. That being said, I still believe that this knife is worth a purchase

It is well-built, comfortable, and corrosion resistant.
This is a fantastic knife for anything. It preps food, it cuts boxes, it follows you into the lake, river, or ocean without complaint. It is razor sharp, holds its edge, and can be used for hard work. It has spoiled me on other knives because of its versatility. Sure, the sheath doesn't have an attachment, but I through a discrete carry clip on it, problem solved. You can't go wrong with this knife.

Nice quality, but watch the surface rust.
Feels good in your hand, great quality.. but it is getting surface rust faster than I anticipated. Make sure you're rinsing it down after every outing.
