With its modern twist on the classic trench knife, this spring-assist knife with knuckle guard is nothing like you've ever seen. The knife mimics the style of the popular combat knife from the two World Wars but adds some newer features that take it to the next level.

Not only is this knife a folder but it also has a spring-assisted opening mechanism that makes engaging the knife with one hand quick and easy. A flipper at the back of the knife allows the blade to pop open with some force from the index finger or thumb.

The knuckle guard on the overall 8-inch knife protects the fingers from close-quarters combat and can be used as brass knuckles in a pinch.

I like this knuckle knife pretty well, but I do have a concealed carry permit. Without such, I could be in trouble with the law if I was to be caught with it, it's pretty deadly, Its a bad assed knife. It fits into a jacket pocket well, and is a concealed weapon. Yes, I like it

It's kind of lightweight but I really like it. Good for the price.

Brass knuckles AND fast open assist in one piece? Totally badass, if maybe not very useful. And most-likely illegal - though I haven't bothered to look it up. It's not a practical use item, as there are better knives and better brass knuckles, though it is solid and quality made. The knuckles are split to allow the blade travel and the blade lock is clumsy to access and operate inside the index finger hole, but the blade opens fast and smooth and locks nice and tight. I don't see taking it out of the house. More like a very cool toy for the collection or a gift idea. This knife/knuckle combo looks great, works well enough and is priced low for the fun. I'm glad I bought it and may buy some more as gifts.

This is a good knife. The only real issue I had with it is that the blade opening is not as quick as I would like. I did adjust it as best I could and did improve on it a bit, however, not exactly what I like as far as the speed of blade deployment. Otherwise a well constructed knife at a good price.

This thing is great. I wasn't expecting this to be that great when I first brought it. But the knuckle guard is solid. For ONLY $10! I am totally happy with it. I love the thing. The blade is really simple but surprising sharp, seriously if your thinking of buying this just get it. For the price you'll be happy with it
