Customer Reviews

Adam C. on Nov 27, 2022

Wanted a small auto knife as many of my knives are just kinda big for EDC (for me anyway) so this one looked good. Well it is. Blade is super sharp and holy poop does that thing come outta there when you hit the button. It felt like it would fly out of your hand if you didn't grip it hard but I tried just baaaarely holding it, very lightly with like two fingers, and it actually stayed in my hand fine. Great knife for sure.

Dinky automatic!
Roderick B. on Apr 29, 2022

A little green bug with a potent stinger! Snaps right open and securely locks up ready to go! Perfect for use in situations where discreetness is needed. A totally perfect 5th pocket knife. Sharp out of the box, and a very acute tip Simply love it!

Launch 4
Chris M. on Mar 31, 2021

I thought this knife looked cool and have other Kershaw's so I ordered it. Not expecting it to be so small. This knife is as small as my pointer finger. I was shocked but man I LOVE IT. Extremely well made as my other Kershaw's, sharp as a razor, and would buy it again in a heartbeat.....

Soo perfect
Mylene S. on Feb 8, 2021

Size and sharpness is just right for quick utility cuts to fidgetting and work.. perfect ergos and minimalist look .. way classy

It's become an EDC!
Tu N. on Jan 16, 2021

I was a little hesitant about getting since I have a bunch of EDCs like Scallion, Tenacious, Bugout, and a Hogue Microswitch CA Legal. I wasn't sure if I'd like to smaller size compared to the others but I really like how it fits into that fifth pock in your jeans. It's sharp and has a great snap to it, not to mention that point and false dagger blade. For $75, it's a great buy.

perfect small edc knife
Paul W. on Sep 30, 2020

I got this knife when it first came out and i have carried it nearly every day since. At one point I dropped it in my gravel driveway and it got driven over a few times, now it has some gnarly scratches, but it still works great and has lots of character. The string did break at one point and kershaw sent me a new one. The size and shape of it makes it perfect for detailed cutting tasks.

Buy this one. You won't be dissapointed
Steve W. on Sep 30, 2019

I didn't know how I would feel about such a small knife, but now that I have it, all of my concerns are put to rest. The Launch series is a winner, and the Launch 4 is a distinctive standout because it features quality steel, a solid mechanism, and in a small package that just works. I hardly know it's in my pocket and fits the bill for having a useful blade when larger ones may be difficult to get away with. Thank you Blade HQ for your quick, professional service!

Great little knife
Van K. on Sep 9, 2019

Solid value and useful size for carry at work in an office environment.

Best lil’ Knife
Elias H. on Feb 16, 2018

This knife is super snappy and perfect for slacks! I work in an office so this knife is used everyday with my slacks and suits! Razor sharp and good for almost any everday task! Great Value and USA MADE!!!

Fast action, beautiful finish!!!
Michael R. on Jan 13, 2018

Got the launch 4 today and it is as beautiful as advertised. Fast auto action, and a perfect OD Green finish. This will definitely be in my EDC rotation!

Jake T. on Jan 6, 2018

My wife got me this knife for Christmas and it’s amazing! The fit and finish are perfect and the action is strong and smooth!

Fast and sharp
Grant D. on Jan 5, 2018

Cool little knife. Came super sharp and opens really fast. Smaller then I am used to for my usual carry knife but makes a good fun utility knife. Good conversation piece. It has worked its way into my usual rotation.

philip r. on May 29, 2017

My first real auto knife and its a home run. Small so its perfect for edc and no one is freaked out when you deploy it. This is my office knife. If they made the same design with 3" or 4" blade I'd buy it.

Very cool very small switchblade
Barrett E. on Dec 24, 2016

Most of my pocket knives are much larger than this. I specifically bought because of its small size. I needed a small knife work work in dress pants. This is perfect. It's very fast as well. I'd say the only downside is no blade lock. I never use a lock if I use the pocket clip but when loose in my pocket it's kind of nice insurance. I am going to carry in a small sheath of sorts. Eventually will pick up the black one as well.

Kershaw Launch 4 CA Legal Automatic Knife
Jeffrey R. on Aug 3, 2016

Received my knife (black) on 8/1/16 and this knife will become my everyday carry now. This little knife works flawlessly and very quick. I would give it 10 stars. I love this little guy, great knife. Worth the $$$, get yours now.

seems to end up in my pocket more than any other knife
Todd P. on Jul 24, 2019

light weight good action holds an edge fairly well

Very nice little knife
Bradley B. on Sep 3, 2018

This is a great knife. Small, compact, easy to carry at work. A great little box tape cutter. I have owned it for about 3 months now. My only complaint is that I have dropped it a few times, and it does scratch and ding up easily. With that being said, it is a really bad a** knife. Snappy, quick, and even being on the small size, easy to get a good purchase on it and do what you need to do. Recommend if your looking to buy a small auto.

Cool, but less than functional
Joey H. on May 4, 2022

Very well made, definitely cool, and cute. The problem is with the button, it sits flush with the scales, so by the time I get enough pressure to deploy the blade, my gorilla thumb is smashing the scales together hard enough to slow the blade down. I will have to modify it to work for me. Add 1mm to button=5 stars.

2 years of EDC use it's ok, but pretty soft steel
robert w. on Jun 23, 2019

the size and speed and ease of handling is great, the cost was great under 80$ the only complaint we have after testing two of these for almost 2 years every day use is the steel is fairly easy to take the edge off and very easy to over sharpen, which is odd since the CPM-154 says it is 58-60 rc, we were surprised at the poor edge retention on both knives. Still worth buying but be aware.
