CR5401: Flavio Ikoma 5401 Seismic
Batten down the hatches. We’re convinced that the word “dainty” isn’t in Designer Flavio Ikoma’s vocabulary. We take his Deadbolt innovation as definitive proof. With it, the Seismic everyday carry folder has proven to be outrageously strong without compromising on simplicity or usability—it’s got other folders quaking in their boots. 

For years, Flavio Ikoma of Presidente Prudente, Brazil toiled over the mechanism that was to become the Deadbolt lock. Finally, it’s perfected: steel bolts interlock with the steel blade and the liners when it’s deployed to yield outrageous strength. The IKBS ball bearing pivot system ensures it opens quickly and smoothly. A prominent button sits at the pivot point on the highly ergonomic G10 handle for simple disengagement. 

As a finishing detail, Flavio added a discreet torx screw in the handle for deployment customization. Modify the blade detent for an easier or more powerful flip that’s all yours. 

Seismic sets a new precedent for strength and simplicity. 

How Deadbolt Works

If you don't own you don't know
I've never understood why fans trash a knife because of its blade steel knowing full well in advance what type of steel was being used? I've got several knives in 4116 and they perform fine as long as I avoid cutting lots of cardboard.. I can dull 3V,XHP, and even M390 in LESS than 2 minutes cutting different types of cardboard and especially cutting plastic pvc pipe.. The reason CRKT is charging so much is simply because it's a new locking system..Remember when Cold Steel use to charge a premium even though the steel was only AUS8? Yep,CS was charging a premium based solely off of the triad lock..Enough about that,let's get into this folder..First off,ergonomics are fantastic.This is the idea size folder for hikers,campers,fishing,hunting,etc.The dead bolt lock is easily maneuvered and strong as a bull..No clue why the other reviews said opening action was stiff? I can flick this open with virtually zero effort.. I knew CRKT was treading deep water because of the price,but to trash a folder based solely off of price-steel, is ridiculous..Buy,receive, and then USE before giving a review.

Confused by CRKT and their choices with this. Big step backward.
Design-wise the aesthetics is pleasing, at least to me, but at this price point I expect much higher quality than this. The new lock is interesting but that seems to be all its got going for it. It's also pretty heavy.Most important of all, and the reason for the score is that holy cow this blade steel is SUCH a regression. I have no idea what possessed CRKT to make a knife at this price point with what is essentially a slightly upgraded 440A(!) steel. When they're also releasing models in D2 at LOWER price points and equal fit and finish, this knife in particular is incredibly confusing. Big swing and a miss CRKT, not sure what you were thinking here.

Really not great especially for the price....
I really like CRKT in general, but I've bought knives for $30 with better quality than this. It has ball bearings and it is a challenge to flip open. The lock is very sticky to press. The backspacer is very sharp and feels horrible against the palm of your hand.All that being said for $120 I would much rather buy something else.
