This, ladies and gentlemen, is the CIVIVI Typhoeus.
(Gesundheit.)
No, the Typhoeus is actually named as far as anyone can tell after the monster from Greek mythology. You know the one -- so tall his head brushed the stars, controlled the wind and breathed fire, had snakes for a butt.
What?
No, really.
Anyway, this incarnation of Typhoeus is not, in fact, so large it brushes the stars. It's actually pretty compact for what it is, which is a 6-1/4" long fixed blade knife shown here in stylin' purple, with a very modern looking upswept drop point blade that's 2-3/8" long. It weighs 81.1 grams or 2.86 ounces, making it quite light compared to many other fixed blade knives.
Actually, no. A fixed blade isn't quite what the Typhoeus is. But it's not a folder, either. In fact, it's kind of hard to describe just what it is, which I guess is exactly why it's here.
You see, it has a trick.
Thanks to its articulated handle, it transforms before your very eyes...
Into a punch dagger. (Yes, another one.)
Well, "dagger" is the wrong word, too. It's only single edged. But still. Can your zooty Zero-Tolerance-Benchmade-Emerson-5.11-Strider-Chris-Reeve even do that? I submit to you that it cannot.
CIVIVI themselves call this an "adjustable fixed blade knife," which I guess is one way to describe it.
Mind you, that's because the one thing it doesn't do is fold. Well, okay, it self-evidently does because you just watched it do so. But it doesn't, like, fold fold. Not in such a way that the blade can be packed up within the handle.
Therefore it comes with this leather sheath, which despite being decently made is unfortunately is rather horrid in how it's designed. That's a shame, really, because the Typhoeus itself is actually pretty well built. The sheath holds the knife only in its punch-dagger configuration, and you can either pull it as such or give it a little twist when you draw to convert it into its traditional mode in the process.
But the sheath is one of those ghastly fold-over retention flap jobbies with a chunky crude button snap on it, which makes it impossible to draw quickly and just plain old annoying to draw at all, what with the damn flap getting in the way and the snap scraping you and knocking against everything. Undoubtedly it would be better served by an injection molded or Kydex sheath with some kind of passive retention. But it hasn't got one of those, at least not from the factory, and not until I can be bothered pressing my own. So despite superficial appearances this is not in any way a self-defense knife. On the bright side, storing the knife in its punch configuration shortens the overall length considerably to just 4-1/2" (albeit now at 3" wide) which means it won't stick up as far to poke you in the ribs while you're carrying it. If only CIVIVI marketed this as a selling point. Instead, they don't seem to mention it at all.
The Typhoeus' blade is, depending on how you look at it, either a design sans ricasso, or is one of those hip and trendy "all choil" dealybobbers. When you're holding it in what's for lack of a better word normal knife mode, your index finger goes in that space naturally. There is no jimping anywhere on it but the G-10 handle slabs are both milled and textured, so keeping a hold on it isn't too tough and its design lends itself to easy controlability. The upswept edge has a cutting profile that presents the entire length as a functional belly, making it quite usable.
In punch dagger mode, a narrow tang is revealed behind the bulk of the blade which goes in between your fingers like so. The ensemble is not symmetrical and the blade is noticeably offset in the handle. While you can hold it either way 'round you'll probably find it more comfortable to have the shorter end of the handle towards your thumb, which is how it will naturally fall if you switch it from the traditional grip to punch dagger configuration anyway.
The lack of a ricasso does present a bit of a problem here, though, because it's easy to nick yourself with the corner of the blade at its base. Even moreso if you're trying to get a grip on it in a hurry, which is probably a further ding against it for self-defense duty. I probably wouldn't want to use it as such, anyway -- there are much better options available.
I was going to take the Typhoeus all apart but I decided at the last moment I couldn't be arsed. The pivots do ride on bronze washers, though, which you can see peeking through the gaps. In total it has four pivot points, with two linkages between both handle halves.
The pivots don't present any perceptible wiggle at all, and the mechanism moves quite freely, to the point that you can just flick it back and forth between modes. This is sure to amuse anyone to no end.
Well, it'll amuse you to no end, and annoy all bystanders in the process. That sounds like a win/win to me.
The Typhoeus' action does not lock in either position. What keeps it there is your grip on the handles, which cam themselves together as you squeeze. Notably, pressing on the spine of the blade with your thumb does make it want to start folding up, and there's probably no jimping there specifically to discourage you from doing that. Keep your fingers instead on the handle itself around the scales and it's not going anywhere.
The made is made of 14C28N steel which CIVIVI take great pains to point out as Swedish. Despite this it is still very much made in China. The blade is 0.119" thick, and I am very pleased to report that it's flat ground. It has an attractive satin finish on it, and bears no markings other than...
...This nearly microscopic steel descriptor laser engraved into it. It bears no other inscriptions or maker's mark, although it does have CIVIVI's "C" logo as an emblem on the head of the center pivot screw:
The Typhoeus is quite compact for a "fixed" knife, as evidenced by how much smaller it is even than a bog standard CQC-6K.
The Inevitable Conclusion
The Typhoeus is a fidget toy par excellence, but at anywhere from $65 to around $100 depending on which color variant you want, it's kind of tough to justify on that merit alone. Luckily, it's also competently manufactured and pleasantly functional in the bargain. If I were you, I'd look at it as a "fixed blade" style knife that's easier to carry than most by magically making itself shorter when you put it away.
It's a shame about the sheath. You'll probably have to add $10 worth of Kydex and rivets to your bill of materials.
