Description:

Andrew Demko teamed up with Cold Steel to create a high-performance production version of Demko's AD-15 folding knife. The AD-15 introduced the innovative Scorpion Lock, which provides secure blade lock-up with a pull-back lever along the spine. Andrew modified a traditional lockback design by integrating it into the handle and adding a stop pin, eliminating blade play and overtravel issues. With Cold Steel's AD-15, the sensation of the Scorpion Lock is now more accessible, coming paired with an affordable, high-quality folding knife featuring tough G-10 and resilient CPM S35VN stainless steel.

Great knife, innovative lock and built tough
Dyami M. on Dec 5, 2019

I have been carrying the AD15 by cold steel for about a week now. Such a great knife.....I have been drooling over the Demko custom AD15 for a while but it is way out of my budget......To get this knife at $160 is a steal. Great fit and finish, really sturdy and the lock is fun to play with. It does have a learning curve....but when you figure it out....it sings! Only complaint would be the texture of the G10 on the clip side, it's a pocket ripper.....Okay on Denim, but would probably tear up your fancy pants...lol

Get one!!!
luke j. on Feb 15, 2019

Cold Steel killed it on this one!! I love Demkos designs but they are out of my budget usually. Cold steel makes very tough knives but alot of them are not super practical for everyday use. Im siked the are making exact production versions of demkos knives instead of thier usual offerings . This thing is super solid, im so impressed with this knife and the lock is super fun to play with , if your a little burnt out on flippers like me this is the cure . Im deff grabbing AD10 after handling this one. Also i want to commend bhq on thier shipping...i paid a extra $20 at checkout for 3 days or less shipping and literally got the knife the next day.

Sweet!
Jacob C. on Feb 20, 2019

Got mine yesterday. It’s a big blade but feels like a tank. Took a little while to get used to the action but I have it down now! Blade came razor sharp with even grinds. Quality control is perfect on mine. This is my first higher end cold steel and I’m not disappointed in the slightest. Only thing I’d change is the pocket clip, very tight, don’t clip them to your nicer jeans without expecting ripping. I’ll be carrying mine mostly in uniform for military use.

first cold steel
Ben D. on Jan 6, 2020

My first cold steel and its great! The clip was stiff. Easy fix, bent the clip a little. The G-10 was rough but a little sandpaper took care of it. Very happy with my purchase

Great Knife for Big Dudes
Waylon W. on Dec 18, 2019

Cool action. Great blade. But its a BIG knife. If you're on the smaller side, you may have a hard time manipulating this knife, or finding it pocket friendly. I Love it!

Amazing locking mechanism
Alex C. on Feb 23, 2019

One of the best Cold Steel has to offer. I find myself opening and closing it all the time. Came super sharp and super sexy haha

No Regrets, Solid Knife
Ross D. on Dec 10, 2019

This knife is a beast. It's large, solid, and tough. The edge is a razor. The construction is quality. The only downside is the clip is very tough and sits over rough G10, this will be rough on pockets. This knife is great and I highly recommend this as an EDC, tactical, or duty knife. Bigger and tougher than my PM2 and Rift.

Great Quality, Bit Big for EDC
pat c. on Apr 24, 2020

The thing is a tank. If i could I'd give it 4 and a half stars. Can't quite give it 5 though as it's just a bit too unwieldy for an an edc. Great sticky G10 and the the lock is tight and impressive. Overall, it would be a good "hard use" folder if you're willing to beat up and expensive piece of steel.

Beefy
Jozef J. on Nov 15, 2019

Now this is a nice looking cold steel. I've been diving into the cold steel knives lately because I really like the sturdiness of the knives. This is no exception. Sturdy and well built. Handle to blade ratio is much better than other cold steels I've had.Fit and finish are excellent.The lock is cool and the knife is unique. The bad parts are the damn cold steel clip. Cold steel clips are crazy to get into your pants. The G10 on the scales is really rough and will eat a pocket up. The lock itself is a little trouble to learn but can easily be figured out with some time. Very nice knife.

So close!
Eric H. on Jan 24, 2020

First off, I know that this is a production version of the Demko's AD-15, so some concessions had to be made to bring the price down. The good includes how beefy the knife is. Super solid as one comes to expect from a Cold Steel offering and I can see how the scorpion lock can be beneficial. The more you grip down on it, the more tight the lock (that blade ain't going nowhere!). Took me a few minutes to get used to how to close it one handed, but overall, not bad once you get used to it. Mine came wicked sharp out of the box and almost got its baptism in blood on my first use. I do like that you can use the thumb stud to either do a thumb roll or use a flick motion to open it. The bad includes how many hot spots are on the knife. The jimping on the spine of the blade is rough and can dig into your thumb. Also, the lock mechanism's edges are a bit square and can dig into the palm. The scales are a bit rough, but as other commenters pointed out, a bit of sandpaper takes care of that. Additionally, for me, the end of the clip sits a tad high and you can feel it when you grip on it tightly.

Close but not quite
Isaac L. on Feb 15, 2019

On paper the ad-15 is great. Full size EDC with a nifty lock and a good steel at a reasonable price, provided you don't mind the weight. In hand, some issues become apparent. 1. The G-10 is aggressively textured and lands right under the pocket clip. This is a recipe for shredded pockets. 2. The knife is a fairly shallow carry. Not an issue in slant pockets, but jean pockets would show about an inch of handle. 3. The forward finger choil is too small. I have average fingers and I was riding forward slightly onto the sharpened portion of the blade. 4. Most importantly, any pressure on the yoke of the Scorpion lock makes opening the blade difficult. Think in terms of pressure on the lock bar of a frame lock. Maybe others will adjust more easily, but I found that my hands naturally put this pressure on the yoke as I went to open the knife using the thumb studs. Overall, it's a nice concept, but it could do with some refinement. Most of my problems could be solved by purchasing the AD-10.
