Fun little thing
Sam M. on May 29, 2021

Crazy sharp, convenient, and good to have. Spyderco quality in a tiny package.

Sierra N. on Aug 9, 2020

This is a great knife for it’s money!! I got it from amazon not expecting much. But dang! Wonderful little knife, I gutted, skinned and processed a deer with this little knife and throughout the whole process I never sharpened it. Yes I’m not kidding skinned gutted and sliced up an entire deer with this tiny knife definitely buy it!

Great little keychain knife!
Ken T. on Dec 4, 2019

For such a small form factor, this thing is high quality. Sharp too!

Nice looking, small but handy!
Bill S. on Oct 29, 2019

Perfect for a keyring and to always have a sharp edge when needed.

Not a gag gift
Patrick K. on Mar 15, 2019

Thought I should get my wife a “gag gift” to poke fun at my recent knife addiction. She thought it was cute, I put it on her key ring and didn’t expect much more from it. Next thing I know she is slicing through boxes and that tough plastic packaging like it’s butter with the thing. Couldn’t believe how much cutting such a small and cheap knife can do.

Big thing in small package
Luke G. on Mar 14, 2019

The perfect box opening knife.

Small and sharp
Gregory W. on Mar 6, 2019

Backup to my EDC on a keychain. Works great for small tasks.

G.I. Joe Sized Knife for Full Sized People
Jacob D. on Feb 22, 2019

This knife pretty much never leaves my pocket and I never notice it's there until I take my keychain out. It is literally impossible to scare anyone with this knife and it almost goes entirely unnoticed. As such, it has snuck into many places where knives are not allowed. Mine has gotten into sporting events, the fair, Disneyland, concerts, and even passed through TSA. Not that I'm endorsing that, but something to think about. Honestly, it cuts just fine and has stayed pretty intact even though it has banged around in my pocket with keys and change for years. Kinda hard to hold if it isn't on a keychain, but you can use your keys to add grip when you use it. I thought this knife would be a total novelty because of the size, but it's fully functional. Good for anyone who needs an inconspicuous knife to always have on hand.

Love it
Chris G. on Feb 11, 2019

Bought two of these one for my son and I. Awesome little keychain knives that actually work if you need them. Small enough to keep on your keys in your pocket without being bulky. Highly recommend it

My Brother’s Wedding
Adrian L. on Jan 31, 2019

My Brother bought a gang load of these and gave them out to all who wanted. And , had all the people in the wedding parties name engraved on the ones they received... Very cool idea... Very cool knife and since then I’ve bought more Spyderco to add to my collection... What better way to introduce people to a great company..???

Tiny spydie knife
KEVIN A. on Oct 13, 2018

I honestly bought this just to add to my collection due to sheer ridiculousness in size but have since fallin in love with it and use it and sharpen it often lol the looks ya get when pulling this bad boy out hahaha but I daily carry 2 to 3 knives minimum so this one is more of an accessory yet I find myself reaching for and using it whenever I can..

Raul G. on Oct 12, 2018

Holy cow, I knew it was small but this thing is tiny, not that there's anything wrong with that. I bought this to add to my key chain, and this is perfect. Very solid and very well built.

Best compact blade
Hunter S. on Oct 12, 2018

I use this as a string attached neck knife very nice great for smaller tasks and handy if you forgot any other knife you normally carry.

Pretty Good
Keegan S. on Oct 12, 2018

This makes a great secondary knife for a keychain or just for a small knife in your watch pocket etc. It might not be the best knife but is there when you need it

Awesome knife for a Keychain
Rex L. on Oct 12, 2018

This knife is perfect for carrying as a secondary/tertiary blade! great for opening boxes, letters, and packages.

Love It!
Marvin H. on Oct 12, 2018

This little guy stays on my key ring. The ultimate keychain knife!

Maxwell M. on Jul 29, 2018

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!
John-William G. on Jun 12, 2018

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 knife
Jacob M. on Jan 5, 2018

Super cool little keychain I put it right next to my continue mission keychain.

Awsome little Knife
Ricardo A. on Jan 5, 2018

Extremely tiny, but super sharp!

Always have it with me
elijah g. on Jan 5, 2018

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. on Mar 28, 2017

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.

It's small . . . really small
Walter C. on Feb 25, 2019

But it's a great conversation starter. The SS Bug, the SS GrassHopper, and the SS HoneyBee make a great trio. Get all 3.

Feels satisfying
Trevor K. on Oct 13, 2018

Pros: It came very sharp, the detent is very tight & has good build quality. Also came in an adorable little box. Cons: The satin finish on the handle scales was a little wavy. Overall a fantastic choice of keychain knife and I am thoroughly impressed. (Note: I got mine from Amazon because I could get free shipping with Prime, sorry Bladehq I'm a cheap sucker :D.)

Great Key Chain Knife
Alec P. on Oct 13, 2018

Great for key chain EDC even though it is made in China.

Awesome knife
Patrick A. on Oct 12, 2018

Although I didn't buy it on bhq I do own this knife and absolutely love it! It's an awesome knife for its price and definitely something to consider if you're looking for a little knife to carry!

Great way to check out Spydercos quality
Kenneth E. on Feb 1, 2018

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. on Jan 8, 2018

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.

Sweet little knife
Dan G. on Dec 13, 2016

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
