Very handy
This knife does not have much of a "point" on it do if you are looking to "jab" or slice something this may not be a first choice but it is very sturdy feeling and sharp. Handy knife for the money and smooth operating

Looks good and is handy
I find this to be a very handy little blade to carry. With my pockets filled with a smartphone and USB dongles, I wanted a knife I could easily carry but not have in my pocket. This fits the bill. I didn't buy this as a fashion item but I am constantly asked about it and people seem to like the looks. The entire package is very light so it is no problem for me to wear it. I wish the chain it came with was slightly longer, but that's something I can take care of on my own. I don't like how the blade has to be open to reattach it to the chain, but it's not as if you're going to slice your neck open with it. I just feel closing the blade shouldn't prevent you from putting it back on the chain. Also, when I received the knife the mechanism was very loose and would open on it's own with minimal "jiggling". I took a tiny torx driver to it and snugged everything up so now it definitely won't open without being tugged on. Which brings me to my final concern, chain strength. I have no idea how much force it would take to break the chain, but I wish it felt more substantial than it does.

Decent tool carried in a unique way
The pocket where I prefer to carry my cell phone is also the pocket I prefer to carry my pocket knife, resulting in scratched screens. I bought the Mantis MU-6 Cyclops so I could carry a blade with me but not have it in my pocket but I didn't want a traditional neck knife, mainly because I prefer to have it over my shirt and I want to be able to wear it with everything. The MU-6 fits this requirement perfectly. When I first received the MU-6 I initially thought someone forgot to put it into the box, the thing is VERY light, which is another plus for what I want to do with this blade. I quickly found that the mechanism was a little too loose and any decent bounce would open the blade. A quick turn with a tiny torx head took care of this and it hasn't backed out again yet. The blade is sharp enough for what I use the knife for, mainly opening envelopes, cutting random bits of cordage around the house, just a basic utility knife. It is not as sharp as I would prefer and I haven't yet tried to sharpen it. Being my first hawk bill knife and how much it curves, it won't be as easy to sharpen as my traditional pocket knife. One thing I am really disappointed in is that the knife must be open to reattach it to the bailout key. It is easy to do but I'd prefer the option to be able to reattach the knife to the bailout key with the blade closed. Bottom line, I find this to be a very useful tool that has a unique way of being carried. I don't feel that this knife is appropriate for a defense knife, but it is a nice addition to my everyday carry kit.
