    I don't lose this one!

    • Familiarity: I've used it several times

    My favorite tiny gerber has been lost and found and lost and replaced at least 6 times over the years, so this lil guy is now attached to my keys and going nowhere fast. It's always where I can find it when I need it.

    Great Mini Knife

    • Familiarity: I've used it several times

    I wanted a light weight knife for multi-pitches in case of emergency and I found it in the Piranha. A nice serrated edge would do the job if I needed it and the bottle opener doesn't hurt either.

    As a note though, if you keep this are for climbing, there is no cover on the blade, so be aware of where you are keeping it. While unlikely, it would be possible that something could slide over the top of the closed knife and be compromised by the knife's edge.

    Sharp and Sturdy

      I picked up one of these as a gift for my girlfriend, who's getting ready to aid The Nose and wanted a small knife that can be kept close at hand without getting in the way of things. Here's what she had to say:

      "I keep it in my big wall emergency kit. Small and cute, yet sharp and sturdy. I’ve used it to cut through a 9.5mm haul line with no real trouble."


        This little nugget is adorable. I keep one on a carabiner on my harness whenever I'm climbing. I've seen people get their hair caught on devices and need to cut it out. Or ropes get stuck on cracks and need cut. You don't think about needing a knife on a climb until you really need it, and then it's too late and people are coordinating how to get one up to you if you're lucky enough to have one elsewhere in the group

        Great Knife

        • Familiarity: I've put it through the wringer

        Super sharp, very well made, and small/light enough to keep on your harness or on a keychain. I've had this knife for over 5 years now and it's still going strong. Because of its small size, I've lost it multiple times over the years. My favorite thing about this knife is the blade, it's very sharp and doesn't need to be sharpened often. Also, because it's thin, it doesn't have as many carabiner requirements as other climbing knives.

        Small and nice

        • Familiarity: I've used it once or twice and have initial impressions

        So small I forget I have it on my belt even when at the gym. Hopefully not too small that ill forget I have it when I need it. So far ive used it to cut accessory cord and it worked great. I guess my only fear is that its so small I might drop it!

        Great Little Keychain Knife

        • Familiarity: I've used it several times

        This tiny little knife is awesome. I leave it on my keys and don't even notice it. The blade is super sharp and works exactly how I was expecting it to. Would be a perfect companion while doing any kind of climbing/mountaineering if you need to cut some rope in a hurry.

        Great convenient knife

          Super sharp and easy to add to your keychain for an extremely handy and practical knife. I have a 4" blade that I rarely use because of its weight and size - when do I want to carry that around? But this one is always with me.

          Itty Bitty

            I love my mini-shank. Although it's not a big knife, it's still nice to have around. Easy to throw on a keychain or purse, and although tiny it's got a sharp little blade. I haven't had any issues with it unlocking by itself, but easy enough to flip out when you do need it. All in all if you need something with a punch that's small, go for the Piranha!

            Baby Shank

            • Familiarity: I gave it as a gift but have feedback to share

            This little knife is pretty rad. I bought this as a small gift for a friend and before giving ti to him i gave it the once over. I realized that this had an incredibly small blade, but with that being said it is very sharp and handy to have in tight situations. This would be the perfect climbing knife or even a low profile tool to have with you and not even realize you have it. Though it is small don't count it out because it is definitely sharp enough to come through for whatever your need.

            Not a show-er.

            • Familiarity: I've used it several times

            Its pretty dang small, that threw me off. But its not about size, its more about how you use it right? Since, ive used this for all sorts of stuff, its really easy to throw on a pair of keys, or a beaner on your harness and just leave it till you need it. The blade is pretty sharp and cuts surprisingly well. I'd say its an awesome little gift to throw in a stocking or a birthday cake to an inmate. I would buy it again :)

            Opens when it shouldn't

            • Familiarity: I've put it through the wringer

            I bought this knife because I wanted a small, light knife I could take with me for climbing. I bought it, stuck it on a carabiner, and pretty much forgot about it, until it poked me when climbing. The rivet that attaches the blade to the body had loosened up, and the blade just fell open. It's not supposed to be able to open when it's attached to a carabiner, but it does. Having an open knife attached to my harness isn't a great situation for climbing. Got rid of this piece of junk knife, and replaced it with a (1st gen) Petzl Spatha. A bit bigger, but much better quality.

            Convenient and Handy

            • Familiarity: I've used it several times

            Super compact and lightweight but yet still feels super sturdy. Easy to open and close. Knife is sharp and it was perfect for preparing some cord before a multi-day hiking trip. Hole is big enough for most carabiners and is perfect hanging from my harness or backpack strap.

            Knives are handy.

            • Familiarity: I've put it through the wringer

            And they are even more handy when they are small and easy to carry so you always have it with you. I keep this little guy in a small zippered pocket on my chalk bag along with 10 feet of half inch webbing and two rap rings. and it comes in handy all the time!

            this knife is super sharp so it goes through webbing and rope like butter. its really nice when there is a ton of tat on an anchor and you are cleaning it all up. when you have it clipped with a biner it wont open, which is smart. most the time I keep it in that pocket but when I have it clipped off I don't want to worry about it opening up on my harness and cutting all my stuff up.

            If you climb in the desert or alpine a lot where anchors slings can be sketchy or missing, this is a must have tool.
