I love this knife. It is an amazingly well constructed, very solid knife, good flipping, just have to get used to the lighter weight and smaller handles. All and all it is a really solid knife nice for edc and flipping 5/5. If yiu prefer lighter flippers this is really good for you.
Good Affordable Flipper

First off, I love the size of this thing. It's a really unique design in my opinion that fits my smaller hands perfectly, and it's cool to show off to your friends. It flips really well and is buttery smooth. It has what I would consider a nice balanced weight to it, not to heavy as to slow you down too much, but not too light where you can lose control or not have enough momentum for some tricks. The design printed on it is OK, it could be higher resolution as it looks a little blurry when you inspect it close up. The design will also wear off around the areas you would expect it like the tang cups and the place the latch grips the handle but its not noticeable unless you really look for it. The only problem I have with it is after a week or two of regular flipping the latch is loose and won't stay properly put. Other than that I really cant find any other major problems with it, it's a nice, small, enjoyable knife to flip!
