ratfacedudeguy's Handy-Dandy Guide to YYR Authentication

P.S.
as to the accuracy, the Mr. Butcher are clearly original, the Acrophobia Chinese copies … you tell me …

I used to have a fake Sleipnir and tried some other copies, I assure you that they are not even close quality wise, and the weight is different too.
I agree China have engineers and the machines just as good as the rest of the world, the thing is, it depends on the manufacturer itself if they want to push quality or not. A made in Japan yoyo made with low standards will be well, bad. When you compare YYR vs Rebellion, you probably have about the same standards because they are designed by Kengo anyway. And the price difference is mainly from the labor difference, not necessarily that they charged high on purpose because it’s made in Japan thus higher quality.
However, fake and real is not even comparable. My fake Sleipnir is not even playable anymore after a few dings because the body got bent.

I do not have to provide anything, as I said I have them and use them for years is true (14) that copies (7), the difference is only in your head and probably in the fact that the Chinese copies you just purchased b-grade (which cost less) and not a-grade.
it is logical that the 7075 is more resistant to shocks of 6061 … but no one ever denigrated products CLYW, the General-YO, the 1Drop, etc. and they are committed with the same material of the Chinese copies of YYR … so where’s the problem? in prejudice of people who do not look past over to the name of a brand … and I repeat, no one ever take away from his head that even the original YYR were machined from the same industry in China who made copies … all in agreement with Kengo itself (clearly years later when that model has now made its history, clearly also creating utilities for YYR same … maybe lowering the production cost of the original ones, while people over another economic yoyo take what, we see that they are still a product of YYR and maybe with time takes his voglis buying one original, to see how much better … (little… imho)

P.S. the Sleipnir to 63 grams. has its perfect weight … only after having been able to enjoy it with the copy I understood why the few bought the Jealousy (Kazuma Ohno signature proto ever released permanently) so they spoke well of what yoyo! Substantially was a Sleipnir of 56 mm diameter, 42 mm in width and 62.7 gr. of weight.

I’m having a little problem trying to understand what you’re saying.
Did you just basically said that Kengo actually made his YYR in China while making people believe that they were made in Japan? I don’t think he will ever do that, and I’m not talking about quality.

I never doubt that you can’t make a yoyo in China as good as if you make it in Japan, the thing is, there is high quality and there is low quality regardless of the location. In the end it depends on the manufacturer if they wanna push it or not.

One of the main problem with YYR fakes is because they were trying to copy a 7075 design in 6061. When you have an optimized 7075 with very thin wall and thick rim and then remake it using 6061 instead, it’s too fragile. CLYW, Onedrop etc on the other hand choose the material BEFORE designing, so they only went as far as 6061 limit can go.

I strongly disagree with this one. Maybe I’m more sensitive than you, but since they are made with different material they totally play different. However if they made the copy with the same 7075 with similar machining standards, most likely I can’t tell.

You have understood what I meant and I apologize for my bad English but I speak solotanto Italian and French, and what I write is the result of google translate translation.

what you say is not correct in my view, the 70xx class aluminums are more resistant to shocks (and therefore harder) than the 60xx class but always alluinio you are talking about and the differences both in physical terms (just as an example the specific weight of 7075 is of 2.81 gr./cm3, the specific gravity of 6061 is 2.70 gr./cm3) that workability with cnc machines … are very limited and the minimum thickness at which we you can push it virtually ugule for both (I have a manual lathe and then I tell you from personal experience).
The first example that comes to mind is the Draupnir and Invaders must die … same specs, same weight (0.5 g more per second) but with different aluminums virtually identical specific weights … virtually even thickness very similar.
Another example is the copy of Sleipnir we were talking about, if it weighs less than two grams must have less material and therefore more original thickness is reduced in 7075

I enclose this table with the physical characteristics of some of the aluminum alloys among the most used, but it is in Italian (I can not find it in English)

Here are the differences in thickness between one sleipnir authentic and a copy (take that) … 1,34mm for both.

Exactly the reason why they are fragile.
I don’t know, but mine definitely got bent and caused massive vibe that can’t be tuned. I can even see the flat part on the cup bent visually.
Never happen or seen on any other yoyo.

Have any of you guys seen the fake draupnirs? (the most recent ones) Those things look like they came from the same file…

In the good o’days you could tell a fakenir by its engraving, but now it’s like trying to tell the difference between twins. Someone will get scammed easy.

Some of these colors haven’t been “officially” released by YYR, but the clear and AP are just scary.

yes, I saw them about ten days ago, I do not think are fake, have you seen the prices? some (only a few pieces, often not available … price owl?) are sold at about 70-80 but most is sold at 350-360 !.. crazy!!!

it is clear that they can not be as strong as the original ones in 7075 but cost $ 20! the sixth part of a YYR authentic … what do you expect … but until you whisk them play well as a YYR … and if you bump them, patiently, $ 20 will get a new one. From the other side, one YYR, is not invulnerable, is not done in “adamantium” and if impacts fort ruins, you will damage the same (always aluminum that is!)
you understand that the material is not a problem for the workability or the thickness and that the cost difference between a 7075 and 6061 bar is ridiculous … then you made two accounts and draw your own conclusions.

They are made with the same aluminum of a 1drop, a clyw, etc … or a rebellion … but already a rebellion which should be “low cost” minimum costs $ 50-60.

P.S. however, now the problem is solved …these copies are no longer available for several months.

Maybe it’s just my brain tricking me but there seems to be something off even visually, like, they have “too much”… shine.

pink and AP were made glossy, and the colors seem to those, is the gold that is too shiny and a different shade… but maybe it depends on the pictures …
