I don't know but the Chinese are notorious for buying trademarks and Name rights from bankrupt German comapnaies to put them back on the market with Made in China slapped on it.
Best example is the once famous Zündapp Motorcycle and Moped company which is now solely produced in China.
The thing is, there are only so many old brands they can re-purpose and in the recent years the Chinese made a lot of effort to try and brand their products.
Most don't really understand the purpose of branding (I think) and just sell the regular trash under some replaceable brand names that sound like they were extracted from a fantasy novel. This is really helpful, since it tells me I just need to find the cheapest position and get it over with.
Some, I feel, have learned how much fucks boomers and retards give about branding and how much trust they have in (((product))) from (((brand))) (see Jack thinking he got quality accessories for his phone and what not). So they start inventing legit sounding names, even better if they are associated with (((product))) in any historical way (e.g. steel -> German, wood working -> England, Japanese looking knives -> Japanese Name etc.), which is clever but still easy to notice if you are not retarded.
And they don't even have to buy the rights to an old name.
The funny thing to me is that most Chinese products of good quality don't try to pull any such punches and don't try to sucker people into buying (((product))) and are often condemned to a life of OEM until the inner circle of buyers enlarges enough for the brand to take off (e.g. Xiaomi was an "in the know" brand for a long time, with people buying them from Aliexpress/Banggood etc. directly since they weren't officially selling in the US/EU yet. Of course their Chinese competitors promptly started to produce fakes to confuse the discerning Laowai browsing for quality Chinese goods.)
On topic: I just looked into the knife video again, and I really don't know how he can make his video look like high bit rate 480p (think DVD) in both 720p and 1080p (which look interchangeable to me). Even in the injected animation it looked blurry. He probably is too stupid and fucks with the encoding when editing, even though most editing programs have presets for Youtube (although YT changed their preferred codecs at least once I think). So you get a retarded combination of Camera encoding -> Jack fucking around -> Youtube getting a seizure and having to re-encode
Edit:
No wayyy

I just went down to 480p and couldn't make out a difference lol
At 360p it gets noticeably more blurry though. Ok, when I go from 1080 directly to 480 I see it, but you have to concentrate.
Normally it should be like night and day.
