What's the meaning of T in plum blossom boxing T50?
T refers to the first letter t of torx.
The T mark in t50 of the plum blossom punch is that the plum blossom wrench is the initial letter T of TORX, which means wrench, and T is the abbreviation. The specification marked with 50 is not the size.
Generally speaking, patents are divided into shape (function) patents and registered names (trademarks). The patent for the shape (function) of TorxPlus has expired, but the registered name will never expire. Therefore, as I said before, only Dongguan Jisheng is authorized to buy "TorxPlus" in China. Others are Yutai in Europe, America, Japan, South Korea and Taiwan Province Province. Although manufacturers without Acument authorization can make exactly the same thing, they can't use the name TorxPlus.
