Flavio Ikoma / CRKT "Deadbolt" Lock

The lock looks interesting, and if they offered the Seismic in D2 for $150, I'd probably try one, but no way for AUS-8.

I've own 5 Ikoma/CRKTs already and I'll certainly buy this one as well, but I'll probably wait until the price on it drops.

As far as blade steel is concerned, I'm no expert but from what little I know, you can sharpen AUS-8 w/a pocket stone and it won't rust like D2.

Intriguing design. That $150 is MSRP. Hopefully the street price is much lower, even more so on the secondary market. High price + crkt + poor steel = no go for me. Don't care how innovative the lock is.
 
Is it just there for thumb flicking?
The knife shouldn't need a detent since the deadbolt lock will hold the knife closed as well.
Looking at the design I don't see that the deadbolt lock will be holding it closed and the knife has a flipper tab so it looks to be designed for one-hand flipper opening which if the deadbolt lock is engaged it looks like that would prevent the flipper from working.

I agree. Furthermore, I believe I read somewhere that the detent strength on this knife is tunable by the user.

Ah, I missed that. I thought the pegs on the deadbolt were the same size but now I see that's not the case.

I read that about it too which is a big PLUS for me.

I like weak detents (but not so weak that the blade will just fall out) which will allow me to open a knife w/just a quick wrist flick. I've got that on my ZT 0850 and love it. Of course, it makes it illegal to own in NYC (and similar jurisdictions that criminalize "gravity knives") but I don't live in NYC. :)

The problem I have with AUS-8 is it doesn't hold an edge very well, and most decent D2 isn't terribly rust prone and DOES hold an edge quite well.
 
Im sure it’s plenty strong but the engineer in me think that the design is less elegant because it requires the use of liners as load bearing part, this mean that the lock can’t function or will be weak without liners similar to the axis lock.
I personally think design like the Triad lock, Ball bearing lock, backlock or the upcoming Steel Will Ant lock is more elegant because it doesn’t rely on liners for strength, hence the knife can be made lighter and thinner. In triad lock for example, the addition of liner only made it even stronger. And the designer has the freedom of choosing aluminum, titanium or steel liners, partial or full liner without worrying about how the liner wears etc. which is a huge consideration for design like the Axis lock.
 
The seismic would make me drool if it was in at least 440C or pretty much anything better than what they're offering.

It reminds me of the Paul lock too. Meanwhile, I have a knife with a Paul lock, and it's 154cm...from like 10 years ago.

Sigh. CRKT.
 
Am i to understand that the 1.4 whatever steel is comparable to Aus 8?

If so, wow. I thought the homefront was expensive.

Cool knife and cool mechanism. But i really dont get why CRKT wont listen to feedback.
 
CRKT always argue that the reason for not upgrading steel is so that they can make their price affordable for the larger market, which is understandable, however when you start charging $120 for a knife that's made out of 1.4116 steel at 55-56 HRC their logic stops making sense. Maybe they need to recover the search cost for the new lock, maybe it's more expensive to work with famous designer, however their target market who need a knife at 1.4116/Aus8A/8cr13MoV price range probably won't care.
Designed for enthusiasts, made for mid/lower end user, yet priced like collector piece. This knife is full of contradictions IMO.
 
CRKT has always given me mixed feelings. I have an original M16 from before the flipper and before the LAWKS, just a damn fine liner lock that I carried daily for a decade. I bet I only had to sharpen it twice a year. Then I had a rollock and it was one of my favorite knives until a material failure put it down. But then they started with soft sleel then cheap soft steel I have a Halligan model that I have never been able to get sharp. They could be great and maybe Ikoma can do what others could not. Show them a better path, the path to our pockets! And wallets.
 
New video with Flavio Ikoma from CRKT's instagram.


EDIT:

Despite being brief, the video is actually pretty informative in pointing out the three contact points for the lock. It looks to me that the longer "flat" bolt contacts the frame at two points and the shorter "angled" bolt contacts the blade at one point.

Are you guys reading that the same way?

Well, there are two reviews of this knife on Knifecenter.com and they are quite bad.

More about the fit and finish than the blade steel though.

At least CRKT and the designer is going to allow other knifemakers/designers to use it in future knives.
 
Knifecenter also let's people post reviews without them having bought the knife.

Just bored idiots who I picture are furiously typing away with cheeto crusted fingers.

We have the same problem in the gun community.

A friend and I both got Seismics from two different sources and fit and finish was flawless. YMMV as always.

1st review, the guy is bitching because he doesn't like CRKT.

2nd review, the guy is bitching about lock stick....on a button lock knife. Yeah....its gonna have some lockstick till it breaks in.

I actually forked out for the knife. the deadbolt does not hold it closed, and it does rely on an adjustable detent. My first impression is that the exterior edges are far sharper than I expected, making the knife fairly uncomfortable to hold. While I haven't had enough time to get a good feel for the steel, I am still kind of attached to my old CTS XHP Cold Steel Recon 1 tanto. much better to hold onto and surprisingly lighter than the Seismic. 2 years of carry, and still as slick and solid as the day I bought it.

Great knife, with some caveats. The edges on the G10 are cut at 90 degrees, and are sharp in the hand. They need to be radiused. The lock does stick, but partially by design. One of the few folders where blade tension, by design, is actually adjustable, outside of the pivot. The complaints about blade steel...I'd rather have a functioning piece that is sharpenable than some bragging rights steel.
 
I picked up a Seismic and can confirm I believe it's overpriced. The ergos aren't that great in addition to the steel being meh. The lock is cool but develops weird hiccups over time. I'm going to keep it in my collection but I probably won't carry it.
 
Well, that is too bad about the handle being like that.

I was considering getting one before, but I will wait and see if they will correct these handle roughness problems.
 
Had one of these come through for review. It feels like the knife is built for the express purpose of using the lock.
