OKNIFE LK Review: A Knife and a Flashlight Walk Into a Bar and Ruin Each Other

I paid $124.99 for this knife with my own money. Which means I can say exactly what I think about it.

Let me start with something I believe deeply: a pocket knife and a flashlight are two of the most fundamental tools in any serious EDC carry. They are not afterthoughts. They are not accessories. They are the foundation.

And because they matter, you should not cut corners on either one. You should carry a knife that is actually a knife and a flashlight that is actually a flashlight — tools chosen deliberately for what they do, not crammed together into a novelty that does both things worse than either would alone.

The OKNIFE LK is a $125 argument against everything I just said. And it loses.

Full Disclosure on This Review

Before I go further, I want to address something. When the LK launched, I watched a wave of YouTube and Instagram reviewers all post glowing coverage within a few days of each other. If you have been in this hobby long enough, you know exactly what that means: influencer campaign, free product, positive coverage in exchange.

I am not going to name names. I used to accept free knives myself years ago and I understand the dynamic. But I stopped because I realized I was being disingenuous to the people reading my reviews. The people sending me stuff were often sending me garbage, and I was smiling through it.

So when I tell you this knife is not good, understand that I have no relationship with OKNIFE, I paid full price, and I have cut myself twice carrying it. That last part matters, and I will get to it.

What It Is

The OKNIFE LK is a folding knife with an integrated rechargeable flashlight built into the handle. The blade is M390 steel in a tanto style with a slightly concave cutting edge, blade length just under 2.5 inches, overall length just over 6 inches, closed length around 3.75 inches.

Weight is just over 3 ounces. The handle is T6 aluminum. It deploys via a flipper tab with a button lock mechanism running on ball bearings. The integrated flashlight tops out at 400 lumens in turbo mode, has RGB modes, USB-C charging, and an IPX5 waterproof rating. The battery is 340mAh and charges in about an hour.

On paper, that sounds like a lot for $125. In practice, it is a cautionary tale.

The Core Problem With This Product

I hate multi-tools. I have said it before and I will keep saying it. Every time you combine two things into one tool you are making compromises on both. Sometimes the compromises are acceptable. Sometimes they are not.

With the OKNIFE LK the compromises are not acceptable because they affect both the primary tools in a way that makes neither one trustworthy.

The knife blade is too short for the handle. This is not a subjective preference — it is a proportion problem. The handle is oversized because it has to house a flashlight battery and LED assembly. The blade is under 2.5 inches.

The result is a knife that feels like a utility cutter or a box opener wearing an expensive suit. The handle dominates the knife. When you are holding it, the blade almost disappears, and the ergonomics suffer because your hand is gripping something sized for a larger knife while cutting with something much smaller.

The flipper tab does not have enough real estate to deploy cleanly. It works, technically. But it takes more deliberate effort than it should, and the deployment never feels confident. On a $125 knife with M390 steel and ball bearings you expect the action to be a highlight. On the LK it is an afterthought.

The Safety Issue

Here is the part I cannot get past.

This knife deployed on me in my pocket. Multiple times. I cut myself twice.

The button lock combined with the deep carry clip creates a situation where the thumb stud or flipper tab catches on your pants pocket as you pull the knife out. The blade opens partway during the draw. If your fingers are anywhere near the blade path when that happens — and they often are, because that is how you pull a knife out of your pocket — you are going to get cut.

I am not a careless person with knives. I have handled over 300 of them. I know how to draw a pocket knife. This knife cut me twice through no fault of my own technique. After the second time I stopped carrying it and put it in the box where it now lives.

An unsafe deployment is not a quirk or a minor flaw. It is a disqualifying defect. I do not care how good the M390 is or how bright the flashlight gets. If a knife opens in your pocket and cuts you on the draw, it does not belong in anyone’s pocket.

The Blade Itself

Setting aside the deployment issue, the M390 tanto blade is the best part of this product. M390 is genuinely excellent steel — great edge retention, solid corrosion resistance, takes a sharp edge well.

The blade came sharp out of the box and the slightly concave cutting profile does give you a natural centering action on rope, zip ties, and cord. For the cutting tasks I tested it on before I stopped carrying it, the blade performed well enough.

But here is the thing: the blade is under 2.5 inches. For $125 you can buy a dedicated EDC folder with a 3 to 3.5 inch blade in M390 or comparable steel with a proper handle that fits the blade, a better deployment mechanism, and no safety issues. The steel on the LK is good. The knife around it is not.

The blade profile also makes cardboard cutting awkward. The tanto tip and the concave edge are optimized for piercing and cord cutting, not push cutting through corrugated material. It drags. For everyday tasks like breaking down boxes it is not the right geometry.

The Flashlight

The integrated light is adequate. Four hundred lumens in turbo mode is genuinely bright for the size and the 340mAh battery will get you 50 minutes at 200 lumens before dropping down. The RGB modes are there. The battery indicator using the RGB ring is a clever touch. USB-C charging is the right call.

But this is not a flashlight I would carry as my primary light. The 340mAh battery is small. Turbo mode only holds for one minute before stepping down. The beam is more spot than flood which limits its utility for close work.

For $125 you could buy a dedicated EDC flashlight that runs circles around this one and a dedicated EDC knife that does the same.

The flashlight on the LK is not bad. It is just the second-best flashlight you could own at this price, by definition, because it is sharing a body with a compromised knife.

The Influencer Problem

I want to circle back to the wave of positive reviews this knife got at launch because I think it matters.

The reviewers who covered this at launch got it for free as part of an influencer push. Watch those reviews and you will hear a lot of “this is really cool” and very little about proportion problems, deployment issues, or the fact that a $125 knife with a 2.5 inch blade represents questionable value.

I am not saying those reviewers are bad people. I am saying free product creates a conflict of interest that affects coverage whether people realize it or not. This is exactly why I buy my own gear. Nobody is going to tell me this knife is great when it cut me twice.

Who This Is For

Honestly? A stocking stuffer for a teenager who thinks it looks cool. A novelty for someone who has never carried a serious knife or a serious flashlight and does not know what they are missing. A gift for a college kid who needs something to open packages with a tiny blade and occasionally needs a dim light.

It is not for anyone who takes their EDC seriously. It is not for anyone who depends on their knife and their flashlight to actually perform when it counts.

Who Should Skip It

Everyone else.

Final Thoughts

OKNIFE makes good products. Their flashlights are excellent and I have reviewed another OKNIFE folder that I genuinely liked. This is not a company without talent. But the LK is a product that should not exist, or at minimum should not exist at $125.

A knife and a flashlight are the two tools you should never compromise on. Combining them into one product means compromising on both.

Add a blade that is too short for its handle, a deployment that caused two actual injuries in my testing, and a price tag that could buy you genuinely excellent dedicated versions of each tool separately, and there is no version of this that I can recommend.

Buy a real knife. Buy a real flashlight. Carry them both. Problem solved.

The LK goes in the junk box. It will have plenty of company.
