Ontario RAT 2 vs Kershaw Cryo

Ontario RAT 2 vs Kershaw Cryo splits a folder framed around edge retention from the Kershaw Cryo with SpeedSafe assisted deployment, and the sub-$50 pocket utility teardown keeps both under the same cap.

You are choosing a folder, not a multi-tool. The thing in your hand at the end of this page should be one knife that cuts, folds, and stays inside the fifty-dollar cap. The difference you can use is already in the matchup: Ontario RAT 2 is the side of the conversation about edge retention and a knife you open yourself, and Kershaw Cryo is the side with SpeedSafe assisted deployment. If those phrases describe the same behavior to you, you are not ready to buy either one. They describe different ways for a blade to leave the handle, and a different hope for how the edge will feel after ordinary work.

What the two names are asking you to pick

Edge retention, on this page, means you expect the RAT 2 side to be the knife you keep cutting with before you stop to sharpen. It does not mean a counted stack of cardboard, a hardness stamp, or a winner’s plaque. This site did not run that cut. Assisted deployment, on the Cryo, means SpeedSafe is there to finish the opening after you start it. It does not mean a measured fraction of a second. Nobody stood over a sample with a timer. You are allowed to care about either trait. You are not allowed to pretend this page proved one of them in a shop.

A manual folder asks your thumb or your finger to do the whole travel. You feel the blade come out. You can stop halfway if a finger is in the wrong place. An assisted folder commits earlier. Once SpeedSafe takes over, the blade is going to the open position. That is useful when your other hand is holding a box and you want the knife open without a long flick. It is a worse fit when the knife lives loose among keys and you do not want an opening you did not plan. The fear is different, so the knife should be different.

Ontario RAT 2 when you open it yourself

Take the RAT 2 seriously when the cut is the whole job and you want the opening to stay under your hand. Package tape, a zip tie, a loose thread on a strap, a blister pack you refuse to tear with your teeth: those are cuts. The edge-retention framing matters here because cardboard and tape are exactly the work that makes a budget edge feel tired. You will sharpen sooner than you would on a steel you did not buy. That is a maintenance fact of ordinary use, not a score. If you hate stopping to touch up an edge, say so before you pay, and read the 8Cr13MoV cardboard page only if that steel name is printed on the listing you are holding. Do not assume the RAT 2 wears that name. This page does not assign a steel to it.

Hand opening also changes how you carry it. You can thumb the blade a short way to confirm it is the knife you think it is, then close it again. You are less likely to “check” an assisted knife the same way, because the check can become a full opening. In a pocket you share with a phone, that difference is practical. It is still not a measurement of pocket wear. No sample was carried for a week.

Kershaw Cryo when you want SpeedSafe

Take the Cryo seriously when one hand is already busy and you want the blade to finish opening. SpeedSafe is the mechanism name in this matchup. You start the blade, and the assist completes the swing. People who like it are usually people who open a knife many times in a shift: stock, mail, a jobsite where the other hand holds the work. People who dislike it are usually people who have had a blade travel farther than they meant, once, and do not want a repeat. Both reactions are allowed. Neither one is a test log from this site.

If you choose the Cryo, practice the first openings over a table, with the edge pointed away from your palm, before it lives in a pocket. Know where your fingers are when the assist runs. That is ordinary caution with any folder that finishes opening itself. It is not a claim that the lock was struck or that a sample failed. For how to look at a liner once the knife is open, use the liner lock inspection. Do not skip the look because the opening felt crisp. Crisp opening and a liner that sits on the tang are different checks.

Choose the RAT 2 if

• You want your own hand to do the entire opening.
• The comparison you care about is how the edge will be asked to work, not how fast the blade leaves the handle.
• The knife will share a pocket with keys, a phone, or a pocketful of small objects you do not want an assist firing into.
• You are willing to sharpen when cardboard tires the edge, instead of expecting a spring to solve a dull blade.

Choose the Cryo if

• You want SpeedSafe to finish the opening after you start it.
• One hand is often holding the thing you need to cut.
• You will practice the opening with the edge clear of your fingers before you carry it.
• You are not buying it to win an edge contest this page never ran.

What this matchup refuses to pretend

No blade length is printed here. No weight is printed here. No steel grade is assigned to either knife. No price from a shelf is copied, because it would be wrong the next time the listing moves. If a seller’s page adds those details, read them there, and notice whether they describe the knife you think you are buying. A different handle color is still the same opening method. A “pro” or a “mini” that this page did not name is a different object. Do not drag it into this comparison to break a tie.

The tie does not need breaking by a spec sheet. It breaks when you answer one question: do you want the blade to finish opening itself? If yes, you are on the Cryo side of the difference. If no, you are on the RAT 2 side, and the rest of the conversation is whether you will maintain the edge. If you cannot answer, you do not buy today. Waiting is cheaper than a knife you are afraid to open.

Carry, close, and the cap

Both names are folders, so both have to close and stay closed in the pocket you actually use. A clip you will not use is not a reason to switch sides of this comparison. A clip you must use, because the knife will fall to the bottom of a bag, is a reason to read the listing for a clip before you pay. This page did not photograph a clip or measure how deep it sits. Look at the pictures on the listing yourself, and ignore any picture that does not match the name in the title.

The fifty-dollar cap is shared with every other page here. If the live price of the one you want has left the cap, you do not “step up” inside this article. You either wait or you go back to the sub-$50 pocket utility teardown and ask whether a folder is even the right motion. A multi-tool does not become a better folder because the folder you wanted got expensive. Gerber Suspension-NXT and SOG PowerPint solve pinch and turn. They are the wrong rescue if your job is a cut.

A short way to decide

1. Say out loud whether the blade should finish opening itself.
2. If it should, stay with the Cryo and practice SpeedSafe with the edge clear of your hand.
3. If it should not, stay with the RAT 2 and plan to sharpen when the edge tires.
4. Read the seller line against the brand before you pay, using the seller page if the storefront looks off.
5. Check the live price against your cap. If it is over, stop.

After that sequence you should have one name, not a ranking. Put the other name away. Owning both folders is the second-tool problem unless you have a real reason to carry two knives, and almost nobody who arrived with a fifty-dollar plan has that reason. One folder, one opening method, one cap.

If the job is a pinch or a screw rather than a cut, leave this pair and read Gerber Suspension-NXT vs SOG PowerPint.

Keep one folder. Then return to the sub-$50 pocket utility teardown and make sure the live price still fits the cap you came in with.
