Another Spyderco Double-Bladed Folder?

[JD Spydo]

As many of you here know one of my all time favorite Spyderco folders of mine is the C-44 Dyad. The concept of having one full sized PE blade and one full sized Spyderedged blade has always been very appealing to me ever since I got my very first C-44 Dyad several years ago. Having the best of both edge types (PE & SE) in one folder is extremely handy for most of my daily EDC cutting chores.

Albeit not everyone I've encountered here on the forums share that same sentiment :confused: >> I've asked and inquired as to why some people did not like the original C-44 Dyad ( or any of the other Dyad models) and I got a mixed bag of different answers. One of the biggest complaints I've heard is that the C-44 Dyad when one blade of it is deployed that the ergonomics and overall feel of the folder just doesn't seem right to them. I've heard that the Dyad just feels awkward in many people's hands when they have one of the blades deployed. They say that they can feel part of the other closed blade protruding in an uncomfortable configuration. I will admit that when I'm using my own C-44 Dyad it doesn't seem as comfortable while working with it compared to most other classic Spyderco folders>> but personally I like the double-bladed concept so much of having both edge types in one folder that I just ignore it and not let it bother me.

So I'm asking you all this?? >> if Spyderco were to go to the drawing board and come up with a Dyad II design that would be considerably more ergonomic and more user friendly would you all then reconsider the concept of having a double bladed Spyderco folder? I think it might just be a simple matter of Sal and/or Eric working the bugs out so to speak. Would adding more comfort to the grip/purchase of the Dyad folder make it more appealing? Because I believe that the concept of a full sized, double-bladed Spyderco folder with different edge types is one with great potential.

Eric has a few multi-blade designs in-the-works. Should be out this year. We designed a Dyad some years ago with two stainless Reave integral locks that we planned to make in H1, but the H1 couldn't be machined on the ramp due to it's work hardening. The ergos were better becaused the lock takes up less space. Then we wanted to make it in VG-10, but the cost was prohibitive. I'll pull it out again for a look-see.

That is incredibly good news, Sal. I wonder what would happen if something like CTS-BD1 was used in lieu of VG-10? I would LOVE to see a RIL Dyad. Count me in--very enthusiastically!

I guess that explains why there aren't any liner lock Salts. I had wondered a bit. I do love the C44, and I'll be interested in seeing if anything new comes out.

In my limited experience working with the material, LC200N seems to grind/machine similar to M4; nice and clean with sharp lines. It will be very interesting to watch the development of a new "Salt Dyad." I have been dreaming of something like this for years. Instead of dual RIL's, I wonder what it would look like if you had one blade supported by the RIL and the other with the BBL (as somewhat the same with the Tusk)? I LOVE that combo on the Tusk. I'm sure it would be a bit tricky to pull off and would likely ruin the design lines of the original Dyad, but that would be an awesome build.

Your idea is great! Would keep it slimmer than the dyad style right?

I love the Dyad ,big favorite of mine. I would like to see a size between the large and the mini . Regards Manixguy

Thank you, SG. Yes, I believe the "Tusk method" would allow for a slimmer build. I think the Tusk platform would be ideal for further experimentation for such a project. I've been toying with the idea of making a dual-bladed folder for about a year. I even purchased thinner M4 blade stock for the project. However, trying to do a double RIL would be a tricky build for me--not to mention trying to find a way to prevent the frame from becoming too chunky. I am ecstatic to hear Sal mention the possibility of such a project.

Right up my alley. Great idea JD. I was actually thinking the other day, I had an image in my mind's eye, of a double bladed Spyderco folder: It would have either G10 or FRN handles, and two blades: One Plain edged in a steel that would go well with a PE, and the other serrated, such as H1 or Lc200N. Man that would be an excellent knife.

It could be called the "Super Salt Dyad". Each blade would be in the 3.5 to 4 inch length. Or, what if one blade were H1 and the other Lc200N, both full serrated?

Perhaps one sheepsfoot and the other drop point or something?

Most of that sounds good to me The LC200N would be my pick for a "Salt Dyad". But if I were to have my ultimate wish I would have a Spyderedged Sheepsfoot blade made with H-1 ( or LC200N) along with a really nice clip point plain edged blade made with either M390 and/ or M-4.

But overall I'm encouraged thus far to see that I'm not the only one who would welcome such a great new addition to the main Spyderco line up. I've even had fantasies of a Hawkbill Dyad and a Reverse S Dyad. Now I know that won't come to fruition any time soon but another full sized Dyad type double-bladed folder would go over much better than the original Dyad did>> I'm certain of it. But it would sure jazz everything up if they did the blades in different blade steels for sure.

This sounds excellent.

Don't forget the Clipitools in the double-blade category- a greatly underated and overlooked little folder....My bottle opener/pry bar variant lives with me on my housekeys and goes everywhere short of the airport

Yeah I'm fullly aware of those "Clipitools" and they are nice for small, less demanding cutting jobs. But what I'm looking for and I'm quite certain that other fans of the original C-44 Dyad are looking for are more full sized ( a blade 3.5 inches or longer) double-bladed Spyderco folder for everyday usage. I think the problem with the C-44 Dyad was the fact that when it was introduced ( early 2000 decade) that it was really ahead of it's time IMO.

Most fans of Spyderco's traditional folders just were not ready for it. Most of the guys I know that grabbed a few of them back in the early 2000 decade when they were much more available were for the most part strictly looking at the C-44 and C-39 ( Dyad Junior models) as novelty, one of a kind collector pieces. But weird guy that I am I actually used a couple of the C-44 models that I snagged and found them to be excellent EDC folders. And I'm not alone on that either because I could easily name off anywhere from 6 to 10 guys here on the forum that also like the C-44 Dyad as a user EDC.

But really the full sized Dyad and/or "double-bladed" models I want to see return and to be used as Every Day Carry folders. But I'm also certain that many collector's would drool over them as well.

The clip position on the big Dyad is not optimal. It is like half way down the handle and essentially feels like half the knife sticks out of your pocket, like an Emerson. Yes I know it is not actually half but it feels like too much. Also it is wide, as expected for a 2 bladed knife, but it is more of a glove box knife than a EDC

[Doc Dan]

The powerlock has that extra piece that hinges the part that locks the blade. I wonder if a modified version of that lock, with a hinge at both ends could be used to lock both blades and keel the knife thin and short?

Where would the spring(s) go?

I keep looking at the Dyad and *almost* buying one....

[harronek]

The Dyad is the most ergonomically uncomfortable Spyderco I've ever used , and it weighs a ton .
I came from the world of Traditionals before discovering Spyderco , so with my history and experience of multi-bladed knives the Dyad was an obvious first choice .
I purchased one and sold it very quickly , I went on to purchase quite a few Spydercos all of which I love and use because those models didn't weight a ton and were ergonomically comfortable to use .
Spyderco was the company that showed me a single bladed knife is the way to go . If you want two blades carry two knives its that simple , multi bladed knives are always compromise .

I would be the first one to admit that the C-44 Dyad as we know it now truly could use some modifications. But the concept of a double-bladed, full sized folder sure fills a lot of my knife carrying needs. I'll always carry my C-44 Dyad unless some better designed double bladed folder hits the market.

As far as weight goes :confused: I guess I'm a little confused on that one. I've heard that complaint many times over the years and it's really just not an issue with me. I'm currently carrying/EDCing probably the heaviest folder that Spyderco probably ever made>> and that is the ATS-55 stainless handled RESCUE model. The folder is truly built like an "Abrams Tank" and it really doesn't bother me at all>> because I still use the **** out of it and I actually feel pretty confident using it. I would much rather have a rigid folder that I can have confidence in rather than have a light weighted one that I feel won't hold up to hard use.

I would love to see them tweak the C-44 Dyad and maybe do one different in a lot of ways. One major complaint I have with the C-44 Dyad is that there is not a lanyard hole or even any place you could modify or install one. But the concept of a double-bladed folder is a good one and very few other commercial knife companies have ever done one as far as I know.

I've been toying with this idea, too. Got a concept designed, engineered, but not built... mostly because I'm not sure if it will work...
Would love to see how Sal and Eric tackled things.

The C-44 Dyad is truly a nice piece of engineering when you really look at it closely. To me it's one of Spyderco's most unique "IN HOUSE" designs and it is great for a lot of different occupations. Over the years I've talked to several of the guys in the fishing industry and other seafaring type jobs who loved it.

AS good as Spyderco's serrated edges are ( Spyderedges) to me it would make really good sense to offer up at least two to three top notch, double bladed folders. As I said earlier there are some modifications that need to be looked at. There is no place for a lanyard hole and/or lanyard attachment>> and if I were going to use it fishing I would have to have a lanyard set up on it.

A lot of the guys have said that it feels awkward when one of the blades are deployed. Others have complained that with that model the clip is in a bad location. Which is why I'm saying either modify and correct the C-44 or just do a completely different double-bladed design all together.
