The Rick Hinderer designed Thermite framelock flipper is a tactically outfitted everyday carry knife. It's a great combination of performance and refinement without the sticker shock. The stonewashed blade is hollow-ground for excellent slicing capabilities with a flat-ground "spanto" tip for strong piercing. It's SpeedSafe equipped, has a framelock with lockbar stabilizer, and a 4-way reversible pocket carry clip.

Kershaw's most underrated knife.
Matthew B.
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.
Kershaw quality
Scott B.
Iím a fan of Kershaw and carried this knife for quite some time. I donít 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. Itís slim with a deep carry clip. Itís a hefty knife and durable.
Fun knife
Mike R.
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 thatís okay. The blade is very long, which is nice, and because itís 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. Iíd recommend it, but I wouldnít buy a second unless something happened to mine.
I'm impressed
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
Amazing Knife!!!
Nicholas V.
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 couldnít 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 wouldnít mind. 8Cr13MoV is a good budget steel but if they would use something a little better with edge retention Iíd definitely buy another!
Its ok..
Shawn K.
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...
Great Knife
Joshua S.
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.
Joseph K.
Pros: Feels great in hand, great price, super sharp out of the box
and just an AMAZING knife.

Cons: Nothing
strong well designed edc

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.
