Does anyone else here have any comments they can share on either the detent or the pivot screw loosening up or being cemented in place?
I ask as a result of the day and night difference between GeorgeMX's experience and mine
His blade loosened up after a day, my pivot needed heat from a soldering iron and a ton of force to break loose. (whatever was on this bolt was sort of a grayish white. Not red, and certainly not the blue they used on the t6 body screws)
Regarding the detent, here's what I've found: The lockbar has plenty of strength to it, but the detent ball doesn't fully seat in the hole when the knife is closed. You can see a large gap when viewed from the side while closed, just the very tip of the ball goes in)
After disassembly I did an experiment. Took out the stop pin, reassembled, and carefully closed the blade. At this point the detent ball was fully seated in the hole and the blade would not shake open no matter how hard I tried. But opening with the middle finger flick was still nice and easy, and the blade springs out much more solidly every time.
The problem though, is that when the detent is fully engaged the blade is so far in the handle that the tip just barely makes contact with the backspacer. Note the difference by the arrows below :
Stock-
Stop pin removed -
Easiest way would be grinding out the finger choil a little further so the blade closes further before it hits the stop pin, but then I need to also remove material from the backspacer for clearance and re-anodize that. Removing material from the stop pin would have the same drawback with the backspacer..... So, I guess drilling out the detent hole in the blade is the way to go in this case? Do I just use a larger drill bit and drill on center? I'm worried if I try with the same size moved up just a hair, the bit is going to just walk back into the original hole. (I have a decent drill press, not doing this by hand... But still, small bits flex, and runout is a thing)
If anyone here has experience doing that, I'd love to hear it

KavikThanks for sharing a detailed experience with the knife that's being dropped. This, imo, is what these forums are for.

Hate to be that guy, but this is not anything close to a wharncliffe. A Wharnecliffe is flat with zero belly, this is all belly. This looks like a tanto that wants to be a sheepsfoot. Interesting looking but I'm a little confused on the utility.

I guess that's it, but every reverse tanto I've seen has a fair amount of straight edge near the handle, this has none.
All that belly looks like it would be good for rocking/chopping but the way the handle is angled that wouldn't work without smacking your knuckles into whatever you're cutting. The handle angle looks like something from a karambit, but this blade curve is like the opposite of a hawkbill. I just don't understand what this knife would be good at. It's probably obvious to someone, just not me.

NotsurewhyibotherI think it would be useful, it's nice to have a little forward cant to your blade.
You're right about tantos being generally narrow bladed, maybe this is a modified sheepsfoot, though the straight line as the spine meets the edge makes me think it could be a sheepsto or a tantsfoot.

I like the looks of this knife but it's just too small unfortunately, if they could make it with a 3.2-3.6" blade that would be great

I'll let you know how the Tactical Geek is after I receive it and play with it & use it for a few days.
As far as the Kershaw Chive, I liked it enough that I will bought a Scallion not long after and that was not nearly as good for me. It never snapped open like my Chive and the tip broke not long after buying it. I still have it, but it's just been sitting in a drawer for the last 10 years.
I'm glad to see MD bringing this RaidOps back. Is love to see more compact folders on here for a good price and this definitely is one of them.

Well, I've had the Tactical Geek Variable X for about 5 days and so far I like it a lot. It has very good action for a flipper it's size. Even when I press down as gently as possible it opens about 90% full. I've never had it not fully open anytime I've truly pressed down on the flipper and at this point I've probably done that 1,000 times, lol. I seriously love this little guy. It's very difficult to see how well the blade is centered because of its shape and being single bevel. That being said, it looks so interesting seeing the different angles of the blade. It truly is a joy to play with and look at and examine from different angles. I've only used it to open boxes and envelopes, but it has done very well for me. I like it enough that considering there's only about 50 in each color, I want to buy another one. If the the vintage blue colored one on their website was available for $200 Is but it right now. I would've bought the regular blue originally, but I couldn't find it from one of the stores I typically buy from and Blade HQ have the black and the grey on sale for a decent amount less, more than 25%, than the blue was and the black plus grey is.
This far I can't say how well it will holding long-term, but so far it seems very good and I love the way it looks. I love the size and the ergonomics is better than I thought they would be, but I wasn't expecting the ergonomics to be great. The blade arrived hair slicing sharp on both parts of the blade. I'm very satisfied with my purchase (#07/50). I just hope I can get one in vintage blue for a decent amount less money than their website because that shade of blue and purple with patina looks amazing to me. With most knives I'm not into the loud and in your face colors, but with it's small size and modern looks I think this will look incredible in that "Vintage Blue". Heck, I imagine regular "PVD Blue" looks pretty darn good because this is a little knife that is made to standout in the crowd.

Has no one purchased one of these knives here yet? My description page isn’t showing if anyone has bought a single one of these knives yet.

Kinda shocked we made it through almost the whole drop with no one asking.... But just watched a review for this knife that says Raidops is a South Korean company, but this particular knife is made for them by Viper Knives in Italy

Actually, my point was that I think the differences are rather large
Sure, they're both a sort of stylized reverse tanto with a belly (which isn't a new thing with either of them) and a thumb hole, and they both have that sort of humpback overall shape, like a frown, i don't know if there's a term for it.... But that's the extent of it. Lots of knives have those traits.
Seems to me the list of differences is a larger one. The contours of the handle, materials used, finger guard is part of the blade vs part of the handle, lanyard hole is part of the backspacer vs built into the handle, tip comes much lower vs the almost spear point alignment of the BM, full backspacer vs open frame with standoffs, completely different locking mechanism
That's what I'm saying, there are only so many combinations of features that can be shuffled together. Eventually there has to be knives with 2 or 3 overlapping traits

there are only so many ways you can design a functional blade and have it fit a human hand.

The frame lock is poorly designed. It's too tight. This is not a matter of breaking it in. It gets completely jammed. Metal on metal grinding. Definitely not worth the purchase. I am reselling it.

Thanks for letting me know about easy returns. I have not attempted to open the knife because I will be returning it. I ordered the ferom Forge wing version, so I will be giving mass drop another shot.

GeorgeMXUnderstandable. And I didn't mean for you to open it up, was just wondering if you could re-tighten it with the included torx tool. They don't generally loosen up without the screw being able to turn, ya know?
I finally got mine to break loose today, with heat and way too much pressure. No idea what they used on the pivot, kinda a whitish gray, definitely different from the nice bright blue Loctite on the 6 body screws though.
More details to come in a review later, gotta get back to work for now

A few months ago the Raidops Aquillo was on drop. Much bettwr blade, better pricing. It didn't make the drop surprisingly. Bring that back and I'm in and suggest everyone else get in on that. Not familiar with this model.

SeetreetsThe Aquillo is S30V steel so I guess you're saying the blade geometry on that matches your use better.
The Blue Shark has an M390 blade which mostly explains the price difference since it is a much higher grade of steel. It's also almost half the weight of the Aquillo which is important to me.
Seems kinda odd to me that your dissing this drop for another model.

SeetreetsYeah..... The Aquillo is a totally different knife
Not "better pricing", LOWER pricing, for much less expensive materials and completely different profiles
M390 vs S30V, Carbon Fiber vs G10.....and thank God no cheap steak knife looking serrations on this one, or i would've passed on what turned out to be one of my favorite knives!
If you're looking for a cheaper knife, nothing wrong with that, but you're comparing apples to oranges here
