This is my first experience with this brand, and I know the name and reviews are wonderful and I can't stand a cheap knife I can't trust, so I typically spend a little more for the quality. Thus far as my EDC, it's been solid. The lock feature on this is definitely the best feature, but it does take a little getting used to if you're going to one hand open and close, but very doable. Sharp, durable blade for everything I've used it for, but I haven't really put it through heck just yet. It is a big knife for EDC, but I'm not a small guy, and it fits just fine hanging on my pocket, it just rides further into the pocket than my usual EDC which is a more standard size carry. It's been a good knife and I'll update this if that changes.

I love large "over-built" (no such thing😎) knives, and this one is awesome! So it might not boast a "high-end" steel, but to me this knife is worth every penny. After some fidgeting and using, the action is superb as well. The Deadbolt lock is tough, and the blade is straight up beautiful! I have other large, even more expensive models of similar size, and the CRKT Seismic is among my favorite. For those having any difficulties with either the action or lock, just add a couple of drops of knife lube and it breaks in wonderfully!

I have long appreciated the value and craftsmanship of CRKT. I have many examples of their knives in my collection.
This knife is another fine example and a welcome addition. It meets the high standards of materials and workmanship that people buy the CRKT brand for.
So, why 4 stars? Because it is designed to be a deep pocket carry knife and trying to draw it out of the corner of your front pants pocket is anything but convenient or smooth. You could pull your pants pocket up into you armpit and still not get the knife free of your pants. I don't understand why more thought is not put into this aspect of the knife's design. It's not that all CRKT Knives have this problem. I own the Jumbones and the Hissatsu and both of these knives draw like a dream.
Personally I took the clip off the knife and I carry it in a sheath on my belt.

The Seismic is a beefy knife. Larger than most folders, fits nicely in a larger hand. Great ergonomics. The only I don't like is the wimpy belt clip. Isn't half the length and width that would make more sense for this size. I find it too hard to clip into anything but my satin boxers.

I've always wanted to get this knife ever since It came out and now I have it and I love it small problem though is that the belt clip broke on me and I had to remove it but other than that its an awesome knife came it extremely sharp and the opening and closing is really smooth!
