Too cute not to have! Favorite little neck knife, it's always on me and that's a really beautiful thing. Even if you are up early writing reviews naked on your phone while your wife sleeps. Nicely built, no play. No problems.
A surprisingly good cutting tool!

At first, I thought of this little knife (and I do mean little; it's shorter and slimmer than my index finger even when open) as a novelty. Little did I know! It's a pretty snappy slip-joint, so you won't have to worry about the blade coming loose. It also comes with a very, very sharp factory edge, much sharper than I expected from a knife with a 3Cr13MoV blade (which is about equivalent to 420 steel). The grind is perfect, the centering is perfect, and when run head to head with an XActo blade to cut model parts from a sprue, it beats the XActo hands-down. Fit and finish are great for $13 knife, and while I admit to light use, mine is showing very little if any wear.

Surprisingly, the ergonomics aren't too bad, although with large hands, I do have to choke up all the way and hold it with three fingers while coming up with creative placement for my ring finger and pinkie finger. It works, but it's really only a "one-grip" knife for me, which is fine, given that I'm mostly cutting very tiny things with it. Again, I have fairly big hands, so your mileage may vary here, but I generally like at least a little leeway in gripping a knife as opposed to just the same grip over and over, including the amount of choking up you're doing. However, if you have smaller hands than I do or even smaller fingers, you should probably find this a fun little keychain knife, a workable and surprisingly useful backup knife, or something perfect for arts and crafts (or, if you're like me, model airplanes).
Great way to check out Spydercos quality
Kenneth E.
This knife is built really well. Blade came super sharp and ready to perform. Action is nice and smooth and won't come out accident. I carry it around my neck along with a cylinder lighter. Great knife if you always want to have a blade on you and not know its there. Legal almost everywhere. Also, checkout the kershaw cinder for a more hand filling ergonomic option. Highly recommend it!
Cute yet handy keychain knife
Nikolaus M.
Bought this to keep in my keychain just in case I couldn't bring one of my standard pocket folders along. Does the job of being a keychain knife well. Tiny. Lightweight. Sharp. Doesn't open too easily. Check, check, check, and check.
Great knife
Jacob M.
Super cool little keychain I put it right next to my continue mission keychain.
Awsome little Knife
Ricardo A.
Extremely tiny, but super sharp!
Always have it with me

I have had this knife on my keys for about 8 years still super sharp and very handy when you need a knife
Awesome Key chain
Austin P.
Very small knife that makes a cool key chain for your keys. Does come out of the box sharp so it is able to be used for minor utility purposes but I would say this knife is mostly for looks.
Sweet little knife
Dan G.
This knife is tiny, but it was just what I was looking for. It is barely larger than a quarter but still is a knife with a good edge. Plus there is a hole in the scales for a chain or rope to hang it from. Very cool
