Cryo SpeedSafe Folding Knife

Cryo SpeedSafe Folding Knife

2012 Best Buy of the Year—Blade Magazine, Men's Journal Approved—January 2013

If you’ve been craving a Rick Hinderer knife, but couldn’t quite part with the bucks, your last excuse has just disappeared. The Cryo is the result of collaboration between Rick Hinderer and the design and production engineers at Kershaw. And we’re sure it will satisfy both your Hinderer craving and the demands of your wallet.

A classic Rick Hinderer design, the Cryo is built of pure stainless steel coated with matte grey titanium carbo-nitride for a no-fuss look that lets the design shine through. Like all Rick’s knives, the Cryo benefits from Rick’s real world experience as a fire fighter and EMT. It’s designed to be a sturdy knife that’s still aesthetically pleasing and feels good in the hand.

For secure blade lock up, the Cryo offers a tough frame lock with lockbar stabilization. The Cryo also features Kershaw’s SpeedSafe assisted opening for fast and easy one-handed opening. Access it with either the built-in flipper or the thumbstud.

Slightly smaller than some Hinderer pocketknives, the Cryo is a superb knife for every day carry. EDC this guy for a while and we think you’ll soon appreciate its virtues. You get the tactical, hard-use looks you’re looking for, a Hinderer design, and SpeedSafe opening in this amazingly affordable Kershaw that’s destined to be the Hinderer for the rest of us.

Technical Specifications


May be used on either manual or assisted opening knives. The “flipper” is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle.


Assists you to open any SpeedSafe knife quickly and easily with a manual push on the thumbstud or pull back on the flipper; built into many Kershaw best sellers.

Frame Lock

A portion of the handle (the knife frame) moves behind the blade to lock it into position during use. This is a safety feature of the knife.

What is SpeedSafe?

SpeedSafe is a patented system that assists the user to smoothly open any SpeedSafe knife with a manual push on the blade's thumb stud or pull back on the blade protrusion. SpeedSafe is built into many of Kershaw's best-selling knives.

How does SpeedSafe work?

The heart of SpeedSafe is its torsion bar. Closed, the torsion bar helps prevent the knife from being opened by "gravity;" it creates a bias toward the closed position. To open the knife, the user applies manual pressure to the thumb stud or blade protrusion to overcome the resistance of the torsion bar. After the blade is out of the handle, the torsion bar moves along its half-moon track and takes over. The blade opens smoothly and locks into position, ready for use.

How safe is SpeedSafe?

Very. SpeedSafe opens when the user overcomes the resistance of the torsion bar. Once deployed, a locking system secures the blade in position so that it does not close accidentally. When releasing the lock, the blade won't snap shut due to resistance provided by the torsion bar. Since the torsion bar provides a bias towards the closed position, it will normally hold the blade securely closed. New SpeedSafe users can ensure safe use of the technology by practicing to proficiency.

Is SpeedSafe a switchblade?

No, SpeedSafe knives are not switchblades. There are many unique features of SpeedSafe knives that make them quite different than knives that are considered switchblades. Unlike a switchblade, SpeedSafe blades DO NOT deploy with the push of a button in the handle or by gravity alone. Instead, the user must overcome the torsion bar's resistance in order to engage the SpeedSafe system. Because of this, SpeedSafe knives fall fully outside the Federal definition of a switchblade. However, due to the complexity and constantly changing nature of these laws and regulations, it is impossible for Kershaw Knives to be aware of every restriction in every location in which our knives are sold or carried. It is the responsibility of the buyer to investigate and comply with the laws and regulations that apply in his or her specific area.

Love this little knife.
The finish is a dark matte gray with black hardware. This makes the knife anonymous and unassuming which can be handy when using a knife around people that freak when shiny blades are exposed in public.Fit and finish is superb and the titanium coating on the handle and blade seem quite rugged. The blade is a non serrated modified drop point with a beautiful profile.
I always think of a knife as a tool first, but many folks think "weapon" first which can put a damper on being comfortable about use and deployment in public. The Cryo (IMHO) is all business without being intimidating or threatening.
The blade is about 2 3/4" long and the handle is about 3 3/4". Overall length is just under 6 1/2" which is a perfect EDC length for me. Gets the job done without making me feel like a zombie slayer.
The knife uses a framelock to lock the blade and man, it is a tight lock up with about 40% of the blade thickness hitting the lock bar. Absolutely no blade play at all in any direction.
The detent is quite strong and will not allow the blade to come loose when closed in your pocket.
The lockbar has a stabilizer just like its XM-18 bigger brother to keep the lock bar from traveling out too far.
The Kershaw "Speed Assist" makes the blade fly out with very little effort. The thumbstuds are not that comfortable to use but this knife was designed to open with the flipper so . . . get over it.
The blade is Chinese 8Cr13MOV steel which I've found to be quite serviceable and also easy to sharpen. Quite sharp out of the box.
The Cryo is drilled and tapped to allow the low rider pocket clip to be fastened to the knife in all four possible positions. Lefties rejoice.

I've never really carried a knife before I bought this one, but ever since a friend let me use his Kershaw blur, I wanted something similar with speedsafe technology. I didn't want to fork out too much for a knife, so I looked at the cheaper Chinese Kershaw models that I can use and abuse and not care too much if I break the tip off. Even though the Cryo is made overseas, it is still built with sufficient quality. When I saw a Kershaw Clash with a flipper I almost bought it, but then I saw how how slim the Cryo was and how the deep carry clip on this knife makes it look like you only have a pen in your pocket and bought it instead. I like how the Cryo is 100% steel and don't mind the weight. It's really not as heavy as people make it out to be.

After carrying it for a a couple weeks it has been great, and it weighs about as much as my small cell phone I keep in my other pocket. My knife came very sharp, blade centered, locks up tight, and only needed a few flips open to get it broken in. The blade, I would say, is border-lining on the small side (2 3/4 inches long), but it is a very good shape and is a perfectly usable and stout blade. It locks up tight when opened, and closes with enough resistance that I am not afraid of the knife opening in my pocket when closed either. The clip holds snug, and in my medium sized man hands this knife feels great.

The thumbstuds, however, are awkward (and you could even say dangerous) compared to other knives I've used. They take some getting used to but once you get the motion down and give it a strong flick up and outward they will work and open very fast. If you don't flick just right you can easily cut your thumb, though. I never use the thumb studs since there is a nice and safe working flipper.

I own quite a few Chinese Kershaw knives and a couple of US Kershaw knives, so I feel that I do have some history to base this review on.
What I really like about this knife is the fact that there is no plastic anywhere on the knife. It's a joy to use; it very quickly deploys, and locks up tight. Easy to open and close, even by a lefty like me. The titanium nitride coating is very durable, it even held up fairly well to being used as a bottle opener (one small scratch).
I like the fact that I don't have to worry about this one, if I do lose it (I don't think breakage is an issue) it will be cheap to replace.
For the price, I haven't seen another knife I like better.

The only thing I don't like about this knife (and I'm not sure if they are all this way, or if mine slipped by QC) is that the flipper seems like it didn't get ground and polished. There is a bit of a sharp edge to it, and it becomes more noticeable while playing (continuous opening and closing), which is addictive with speedsafe knives. If I had a choice I would've only taken off a half of a star rating it a 4.5.

This has been my EDC for the last week or so, and I think it's going to remain my EDC for quite a while.

I recently received this knife and can not find a negative thing to say about it. I was worried that it may be too small but it feels and looks much bigger than the actual size. It cost me $31 but I still would have nothing to complain about if it cost me 2 or 3 times that much. It seems very well designed, well made, comfortable, solid frame lock, well centered blade, attractive finish, small and light enough to carry all day yet not too small to be effective and pleasant to look at. What more can I ask for in a $31 knife? Quality is on par with many of my Japanese, U.S. or German made knives that cost much, much more. I find that Kershaw has incredible quality control on all their products including their overseas products and the fact that it is made in China is what keeps it so inexpensive. Otherwise, my guess is that this knife would cost somewhere around the $100 mark. The great design alone is worth the price of admission. Not to mention the ergonomics, solid feel and incredibly sharp blade. Being a knife collector, I find this knife to be one of the best values available. Highly recommended!
