It's SpeedSafe equipped, has a framelock with lockbar stabilizer, and a 4-way reversible pocket carry clip.

Customer Reviews

Pretty, and Pretty dang Awesome
Matt L. on Jul 11, 2019

Beautiful knife, large and eye-catching. Really neat to have a cheap knife by a legend of a knife designer. Has the standards: sharp, solid lockup, easy to close, and fast opening. Then the Thermite goes beyond: unique and functional gimping, nice blade shape, good deep carry pocket clip, feels mean in the hands, and just looks great. Only cons are that with heavy use the clip can create a hot spot and some may consider this knife too big or heavy. But disregard those people and buy this one before they are all gone. 89/100

Great Knife
Joshua S. on Jul 27, 2016

It doesn't get as much attention as the cryo, zing, chive, or skyline. But I would grab this knife before any of those. It's also a nice entry level Hinderer.

Good EDC
Felipe V. on Aug 25, 2018

Like how it feels in the hand, find it considerably thin in my small hands. Flips feels solid. G 10 handle has good grip. Blade matetial is easy to sharpen. Overall a great budget flipper.

Joseph K. on May 19, 2016

Pros: Feels great in hand, great price, super sharp out of the box and just an AMAZING knife. Cons: Nothing

Kershaw quality
Scott B. on Jan 13, 2018

I’m a fan of Kershaw and carried this knife for quite some time. I don’t have anything bad to say. It opens smoothly with the flipper or studs, the handle is grippy, and it has a good blade shape and length. It’s slim with a deep carry clip. It’s a hefty knife and durable.

Unbeatable for the size/$
michael w. on May 25, 2019

You can read the other comments. Grab one of these before they are gone? I love the blackwashed version even better.

Spanto for cheap!
Anthony W. on Aug 27, 2018

Very nice fit and finish on the knife I received. Lockup is at about 25% which is astounding for the price point. Lock bar stabilizer works well. The only hit in my opinion is the thumb studs. With a flipper and stop pin, they are not needed. Other than that, this is a phenomenal knife for the price!

Great EDC
Brandon B. on Jul 8, 2018

Can't go wrong for a budget EDC. Flips open really quick, fit and finish rivals that of knives twice the price, feels solid and has a nice heft to it. It does not feel like a cheap knife, the steel may not be s30v, but I've found it easy to sharpen and it holds a decent edge. I'd say this and the Cryo II are easily my two favorite Kershaws. Both are solidly built and feel very comfortable in the hand.

Amazing Knife!!!
Nicholas V. on Oct 27, 2017

First off, I got my Thermite from my local Gander Mountain store which is gone now for around $50, but I used some gift cards and purchased it for about $30. Man do I wish I bought it from Blade HQ! I love you guys! Always putting out great info in your videos and on your site! For $22 this is one of the best knives you can get! As soon as I got this knife I put the pocket clip in the tip up position with no problems (sorry for those who couldn’t change that because of the Loctite issue :/) It was very sharp out of box which I just love from Kershaw! I did change the angle but man does this go through anything you need it to. For the size it is the perfect weight for me and the ergonomics are amazing for my hands. If you need a knife that can do it all on a budget, then this knife is a great option! I would however like to see this in different steel options if Kershaw wouldn’t mind. 8Cr13MoV is a good budget steel but if they would use something a little better with edge retention I’d definitely buy another!

I'm impressed
MARK G. on Dec 29, 2017

Blade hq recommended this knife as fitting my requirements it is beautiful smooth opening and came razor sharp most knives do not come this sharp from the factory the great recommendation and I'd recommend it to anyone looking for a good EDC knife for under a $100

Awesome for the price
Ben W. on Feb 23, 2019

For the price, this knife is hard to beat. It's a great design at an affordable price. I've been wanting one for a while but when they were discontinued I quickly picked one up and I'm glad I did. This knife is reminiscent of a stretched out Cryo and a tactical version of Boker's Urban Trapper. Overall a good knife at a good price.

Budget Rick Hinderer
Richard G. on Feb 4, 2018

This is a very slim blade and has a deep pocket carry clip so even though it’s a nice size blade it disappears in your pocket. It’s a Rick Hinderer design, albeit with cheaper materials, but still… My only gripe about this knife is that rust developed near the thumb stud. I removed the thumb stud to clean up the knife but the thumb stud didn’t ever tighten the same. It eventually fell off and I lost it, but since it’s a flipper with speed safe I never sent it in to get fixed. Build quality: 4 stars Materials: 3 stars Aesthetics: 3 stars Personal likability: 4 stars

strong well designed edc
Christopher L. on Jul 29, 2015

I've been interested in this knife since preproduction. Hinderer knives, customs or ZTs are out of my price limits. This full size import as well as the g-10 Cryo fit my needs. The only crutch for me on this one is weight. I love it but I know I won't carry it as much because it's a little heavy.

Big 4 EDC
Rade O. on Sep 12, 2019

Like the design, fits my large hands well, like blade shape, good lockup, centering a little off but not enough to matter, nice quick opening and easy to close one-handed. A little big in the pocket but not a problem. Don't really need the thumb stud with assisted opening. Only negative is that it arrived dull and blade grind at the tip was not even; could not process cardboard until shaped and sharpened. 8CRMOV13 easy to sharpen with Work Sharp. For the price cant complain and good for my use.

Kershaw's most underrated knife.
Matthew D. on Jan 21, 2018

This thing was great. even though the gimping sucked, it rivaled the rat 1 pretty good. The g10 scales were nice, the spanto tip blade was useful, the clip carried great and it felt rock solid. The spring snapped on mine after awhile though and I just never felt like sending it to kershaw to get it fixed. Great for the price, you cant go wrong with this one.

Fun knife
Mike R. on Jan 5, 2018

I wanted another Hinderer after owning the Cryo II. I like this knife, but I love the Cryo II. I could do without the designs on the g10 side, but that’s okay. The blade is very long, which is nice, and because it’s so slim plus the deep carry clip, it rides perfect in my pocket. I appreciate the frame lock, but also the stopper to keep it usable for good. For the price... hard to beat. I’d recommend it, but I wouldn’t buy a second unless something happened to mine.

Its ok..
Shawn K. on Sep 24, 2017

Overall this knife just doesn't do it for me. The action is a little off and the lockbar is worrisome. The overall build is good enough but the lockbar just doesn't feel solid. The thumb studs are completely useless as well...
