Hey everyone,
This project started when I first met Dew Hara in October 2017 at the 2017 Seki City Knife Show, where he was displaying his handmade knives in his home town. When I first saw his designs, they immediately grabbed my eye - then I picked it up, and was even more impressed when I felt the incredibly smooth action. Apparently, I was not the only person taking note of Dew’s work - just a few months later, Dew’s “Raikiri” knife won the “Most Innovative Knife” award from the editors of EverydayCarry.com in their “Best of SHOT Show” roundup.
When Dew makes custom Kabutos by hand, the pivot mechanism is built around a R188 bearing, like those used in fidget spinners. We first considered utilizing the same setup in our production version, but our partners at WE Knife found that variances in the thickness of the bearing races from at least two suppliers were not consistent enough. The result would have been a high likelihood of some lateral blade play, which we all agreed was not acceptable.
At WE Knife’s suggestion, and with approval from Dew, we decided then to try a more proven system of pivot barrel and caged bearings, which we found on the prototypes was able to preserve the fast, smooth action - both opening and closing. And really, that’s what makes this knife really fun and useful - being able to swing the blade open and shut, quickly, with one hand. The addictive nature of this action did prompt us to make one production change, which is having the steel used in the backspacer hardened in heat treatment - the same as a stop pin would be - to withstand repeated impact from the blade tang.
Dew and I had a chance to review the final production samples together in Las Vegas at GX (the USN forum’s 10th annual Gathering), and I am pleased to say that Dew gave them his enthusiastic seal of approval.

Thanks for checking out the drop - and make sure to check out the video posted in the Description; I hope it helps to show the sweet action on this until you can get your hands on one of these to see for yourselves.
A few housekeeping notes as the drop kicks off:
* This drop is limited to 600 units. * All units from this first pre-production drop will be serialized. Units in future drops will not be serialized. * Our Estimated Ship Date is February 15th, 2019.
Carry On -- Jonas

Hmmm interested. Would like to see it in a 3 inch blade . I have an issue with the pocket clip too deep carry is not a huge issue ( I have a zt0450 and read that complaint all the time but after having it for 2 years think a dcpc would deminish the functionality of that knife) with me left hand carry is ... Looks like this should be an easy option to add to this knife.

If there was ever a knife that need an aftermarket fix this is it.the clip is one of the reasons I won’t be carrying mine in the regular rotation.sometimes you just have to admit you stepped on it,and fix the problem.(new clip design).

This knife looks good to me but that pocket clip...... i understand that deep carry isn’t everyone’s cup of tea but I don’t think anyone wants a full third of the knife sticking out of their pocket. Hard pass for me unfortunately

Sigh. I don't likes knives with skinny handles or handles that taper as one goes away from the pivot. If the handle were different, I would have to get this. The red one is gorgeous. The Video shows what looks to be fantastics mechanics. Maybe I should go buy that lottery licket. Also, I wonder about all the moving parts. My pockets are usually dirty. I wonder if exposure to high crud levels would gum up the works here.

I can't decide if it's a beautiful, modern looking knife, or a weird ugly one! But I am tempted, just because this is such a unique design! @JonasHeineman is this drop made of serialized units, or non-serialized?

Dew Hara should try to get his logo embossed/engrained/whatever the word is into the pivot. Because the logo has a small circle as part of it, that can be where the bit goes. Or maybe just use the logo on the button lock. I think it would look pretty cool.

Serial #001, that's awesome. I know a lot of people don't like #001, but I'd love to have it. I'm a weirdo with numbers, so I'd love #002 even more just because it's the only even prime number, which is a reason I've always loved the number two.

Yes, I hope this is just yours and I hope Massdrop fixes it for you or replaces it because it really is a beautiful knife and the wood gives it a very original appearance. I can't think of any knives with wooden scales/handles that look like this. I can think of a couple Dew Hara customs that look somewhat similar but they are significantly more money than I'm willing to pay. This instantly became a collectors knife for me. I doubt I will ever cut anything with it, other than a little bit of hair on my leg when I first opened it just to test out the sharpness and it succeeded. I'll continue playing with this knife (just opening & closing) but I won't be carrying it around and it certainly will never be one of my EDC's. I don't think I'll ever sell this... unless it gets a crazy resale value like $900, hahaha. I just love looking at this knife and playing with it. It's just so unique that I seriously doubt that I'll ever see a picture of any other knife that I mistakenly identify as a Rosewood Kabuto. I love and prefer small & tiny knives, but I absolutely love this thing. I hope that Massdrop gets everything taken care of for you.

Got mine, #RW088. Action is awesome. Does We make any button locks? I don't think they do, but they should make some with action like this. What I like least are the useless thumbstuds. I remember commenting on it before but I'd forgotten about them until I got the knife. Even if they function as a blade stop, they don't need to be high off the blade and sharply ridged.

I love the knife but the thumb studs are puzzling. They don’t act as a blade stop in the open or closed position. They touch absolutely nothing.

I had the exact same thoughts. I completely forgot about the thumbstuds until I received it on Saturday. Without being used as a stop I don't understand why they were put on this knife to begin with. That being said, it's an absolutely gorgeous knife. I was worried that the rosewood would not look as good as I hoped it would, but it definitely does. I was thinking that I was going to regret buying the rosewood instead of the Slate G10. Now I just regret only buying the rosewood 🤦🏼‍♂️

Just got mine in (red g10) and love the action - this is absolutely a fidgetter's dream knife. The way the pocket clip protrudes from the knife is awful, though. Any real cutting tasks will result in some pretty immediate discomfort with the points of the standoffs jabbing into the palm of your hand. My Torx tool is at home, so I have not had the chance to tinker with it much. Overall first impression is that it's a rad concept, especially the action, but the clip design/execution is a borderline deal-breaker.

Received mine today (rosewood). Looks nice, great fit n finish, button lock mech functions as expected but the ergo's are real bad on this knife. It's awkwardly thick in hand and has numerous hot spots. The clip being the worst. I purchased this knife for it's uniqueness so it i'm ok with it but i'm sure others will complain.

I agree with these comments, I got the rosewood and it's unique, but not going to be a very functional knife. It's too thick overall and I actually think the blade is not large enough to look proportional to the handle as well. The thumbstuds are just clutter, would've been much cleaner looking without them. The clip just looks silly with the huge standoff. Not the best design brought through the massdrop collaboration team, but you can't have all winners for everyone's taste, just waiting for the Orca to ship out now!

No, the pre-order drop ended a few months ago. But we will have more available to ship from inventory once we make sure that all members who joined the first drop have received theirs and are happy with their knives. If you click the "Request" button, you'll be notified when the drop is live again.

MD, in response to MichaelT's comment, China produces some very fines knives. If you have a good price on one that I really need, I, for one, would buy it.

Decided to drop out of this and went with the Bestech Shrapnel drop instead. This just isn’t as practical as a typical thumbstud/flipper knife considering how the knife is locked close. Also looking at the picture of the button below it,s protruding a lot that‘s making the thickest point 0.7 inch thick. I can see how the the button can get snagged a lot. Overall it just doesn’t feel as practical as other offerings out there , and it’s designed more as an art knife of fidget toy than a more practical edc knife. I bet it can still be a fun toy though

I don't see the point of the thumb studs if you can't open the knife without pressing the button lock. Shouldn't they just be removed altogether?

To me, this looks like a FF Falcon with the ergos made a lot worse. The handle being slightly longer could make things different. This is certainly one that I would never order without holding it my hands. Even then, I doubt that I would be on bored. But rejoice, Knife Fans! This is no where near as ugly as that AC Cobra. On a positive note, I really do like the color scheme of the red scales and BW blade.

Obligatory question - how far off is the production version going to be compared to the one shown in picture here? Are the hardware finish going to change? Is Dew’s logo going to get removed for “cleaner look”?
