I'm almost feeling like I'm being personally called out, here.
This is the "TZGUO" model Q19. As I'm sure you're getting tired of me telling you, both the brand and the model on this thing really don't mean much; you can find this and many of its near identical siblings wherever Chinese white-box goods are sold, under a near infinite array of names and non-brand monikers. This particular instance came from Amazon, hence the unpronounceable five letter combination. The fact that it sneakily violates the "no balisongs on Amazon" rule is just delicious icing on the cake of overt cheekiness. You can also find these all over AliExpress and probably Wish and Temu by now, too, where they're cheaper and you can score one for about $35. The search term you want is "titanium design balisong," apparently.
But never mind all that. Just check this thing out.
The Q19 is a balisong utility knife. It takes standard Stanley style trapezoid blades, as are readily available everywhere.
It has a spring loaded latch, too.
Does that remind you of a particular knife? It certainly reminds me of one... Mine!
Now, I don't think I've been scooped, here. Rather, I think this is a case of convergent evolution, as it were, with both myself and whoever is churning these things out arriving at some similar design conclusions for similar reasons.
And it turns out I like The Q19. I've actually been using it as my daily driver for about the past two weeks, which is why you haven't seen me blathering about much of anything else in the interim. And this will go a long way towards explaining the tape gunk stuck to the blade in some of these pictures.
The Q19 is, as implied by its product description, made of titanium. Well, a lot of it is, anyway. The handle scales and latch certainly are. A magnet reveals that the blade carrier and clip are actually steel. That's fine, and the combination of materials adds up to a total weight of 76.5 grams or 2.7 ounces exactly.
It's definitely more of an "EDC" size and not a competition sized knife, measuring out at 4-9/16" long when closed including the tail of the latch sticking out, and precisely 7" long when open with a typical blade installed. It's square in profile with flat sided handle scales, 0.416" thick not including the clip.
Said clip is a traditional design and rides in a little pocket machined into one of the handle slabs. Of course it's not reversible, with no matching pocket on the other side, because this is in accordance with the deeply rooted worldwide conspiracy among all balisong manufacturers everywhere designed specifically to annoy me in particular, wherein it is also on the wrong side of its handle.
Ahem.
Anyway, the heel of the blade contains a slotted screwdriver tip or, as it's described in the specs, a "pry bar." And the hook on the end of the latch functions as a bottle opener. The manufacturer is thus pathologically driven to bill this as a multi-tool.
Fair enough, actually. The tailhook does open bottles like nobody's business -- provided you manage to lever it the right way around, and don't try to use it backwards.
I spent some time trying to research what the Q19 is a knockoff of and ultimately came up empty. If anything, the closest I can come up with is the Artisan ATZ-1823PO, the now discontinued utility knife version of their Kinetic Tool thing. This certainly has a T shaped latch strongly reminiscent of the Artisan one, although that isn't spring loaded and this is. And the Artisan tool has that weird combination switchblade/balisong action which this certainly doesn't.
Annoyingly, then, the Q19 appears to be a more-or-less bespoke design that against all expectation actually turns out to be pretty good. Yeah, I'm just as surprised as you are. That's not how these things are supposed to go.
Its action is excellent, for a start. The titanium handles are fairly light but the Q19's balance is spot on, with the center of gravity remaining well inside the handles and not out in the blade carrier. The pivots exhibit no drag and are totally consistent in their nearly complete lack of friction throughout the entire range of travel. The rebound is pleasant and distinct, without setting up any vibrations or resonances in the handles. And thanks to having an extension spring driven design ripped off directly from Benchmade, the latch is held out and away from the handles at all times and can't strike either one during manipulation. It just feels good overall.
You would think that the bottle opener hook would make it snaggy as all hell but somehow it doesn't. The knife is thin enough and rides against your pocket tightly enough that it doesn't seem to cause an issue. The only real fly in the ointment I can see from a design perspective is the prybar tip sticking out of the end, which might get in the way if you're trying to do over-the-finger spin tricks. I guess if it bothers you, you could just grind it off. It's a $35 knife with no collector's value. Who cares?
Hier ist Der Viggletesten.
The Q19 scores favorably here, exhibiting very little wiggle and absolutely zero tap of the blade carrier against the insides of the handles.
Yes, this is a $35 knife wherein a significant portion of it is constructed of titanium, and it has ball bearing pivots. Nice ones, too. And the inside faces of the handles are pocketed for the bearings, so this wasn't a case of some existing design somebody just decided to slap bearings in and add $2 to the bill of materials. No, it was designed for them from the start.
Here's the latch spring mechanism, which is dead simple and suspiciously similar to that of the Benchmade Model 42 and subsequent knives. It will spring open from either the latched or unlatched positions if you give the handles a hearty squeeze together.
The Q19 also has a Zen pin design without the need for kicker pins to be pressed through the blade carrier. This is just as well, because every time you see kicker pins on a cheap Chinese knife they're invariably pressed badly. In this they're just basic straight pins with no shoulders or fancy features, but they sit acceptably square when assembled and don't cause any problems or weirdness.
You might think at first blush that installing or changing a blade in this requires tools, based on the two little Torx screws on the blade carrier. But those are a cost cutting measure, not a mechanical necessity; they obviate the manufacturer from having to machine a narrow slot into the blade carrier and instead allow it to be assembled out of two pieces which has got to make it much easier to manufacture. Rather, the nubs that engage the cutouts in the blade are actually mounted on a flexible prong, which you can pull down with the aid of a fingernail just far enough to allow you slide it in and out. If you're chicken you can still install a blade the hard way, by removing those two screws and the top plate. But that's not actually necessary.
Again, this is highly reminiscent of how I do it on all of my printed utility knives. Obviously great minds think alike.
The pivot screws have anti-rotation flats and the handle slabs do indeed have matching D shaped cutouts in them for once -- on all four of them, even. Thus undoing the pivot screws is easy provided only that you start reefing on it from the correct side. There is no visual indicator on either of the screw heads which is the male side and which is the female. But you'll quickly discover that the female side refuses to turn, which clue you in pretty quickly. The Torx head on that side is thus ultimately just decorative. You can install the pivot screws either way around depending on whatever suits your fancy.
The Q19 comes in a pretty nice woven-textured box, and I was surprised to find that it even comes with a nearly complete set of replacement hardware inside as well. It comes with a spare clip, too, which may be an addition prompted by the smattering of reviews on Amazon bitching about said clip breaking. But I can't prove it. To be fair it is only held down by one screw, so I imagine if you were truly hopelessly uncoordinated it's possible you could rip the clip clean off of the knife. Remember, kids: The clip is for carrying the knife on the inside of your pocket, not for dangling it out in the open off of your belt to get snagged on every damn fool thing you might happen to pass by.
You get two replacement assembly screws (all five are the same, including the one mounting the clip), one each of the male and female pivot screws, one spacer barrel, and a clip. You don't get a replacement spring, though.
It also comes with a box of "WYNNS" utility knife blades, so you don't even have to get on your bicycle and pedal down to the hardware store to get your own. These aren't great, exactly, even easily outperformed in edge retention by those in my cheapo 100 pack from Lowes. But they'll do to start with. Of course you can mount any Stanley style blade in this provided it's thin enough to go in the slot, including fancy composite edged or even the forever-sharp ceramic ones.
Oh, and the handle slabs are completely interchangeable so when I put it back together I swapped the bite side slabs, so I could put the clip on the correct goddamn side of the knife. I will begrudgingly re-award the points I docked for this originally, even though it should have come this way from the factory in the first place. Dagnabbit.
While we're flaunting that Benchmade Morpho, though, let's do our usual size comparison thing.
The Q19 is actually very similar in proportions to the Model 32, the smaller of the two Morphos. It's smaller than my Rockhopper balisong, although not for any mechanical reason -- I just designed the Rockhopper to be longer than it strictly needs to be for comfort purposes.
Open it's the same story, although both the Q19 and my Rockhopper's blade carriers are shorter overall than a normal fully steel blade probably would be.
The Inevitable Conclusion
This is pretty much the second coolest box cutter in the world. (The absolute coolest, of course, would be the one I designed. But I would say that, wouldn't I?)
In fact, the Q19 is way better in reality than it has any right to be. I can't find much of anything to complain about, really. It's actually built rather well, it's slick as all fuck, it has all the features, and the price is right, too.
Plus, I think it'd probably make a good introduction for anybody looking to get into balisongs. With a spring latch, titanium handles, and ball bearing pivots all in one package you really can't go wrong. And it's worth mentioning that it's significantly safer to be fucking around with than a normal live bladed balisong, for two reasons: One, you can just take the blade out of it if you feel like it. And two, even on the sharp "bite" side of the blade carrier, about a third of it has no edge exposed. Unless you're holding the handles really far down it's a fair bet you'll just whack the blunt part against your index finger rather than find yourself contributing an express blood donation.
Usually I spend all of my time with this type of thing damning with faint praise. Oh look at the little thing, it thinks it's a real knife, isn't that cute? But with the Q19, I can do no such thing.
It has all the hallmarks of crapness. It's a Chinese made, cheaply sold, generic and endlessly rebadged non-brand product that, for once, actually turns out to deliver 100% of what it promises. I'll be damned.
