verbose "Yu Che" screwdriver (detective story)

I have a magnetic slated screwdriver in my
possession that has a certain attitude to it,
however the amount of data on the handle seems
a bit over the top.

Also this is a case where Google failed (or the
Internet did, or my usage thereof) as
I couldn't get any hits on either the presumed
manufacturer's name, nor the ISO standard, nor
the patent number.

Here is what it says:


Yu Che the company?
VPA GS (part of the logo)
ISO 2380 [1]
Type 38 product reference?
CR-M chromium, magnetic?
1.0X5.5X100 ??? * width * length
PAT M9803920.2 patent number? what's there
to patent in just another
magnetic slated screwdriver?


[1] This page seems to have something to do
with it,
https://www.iso.org/standard/35869.html ,
but I can't find the particular material on
ISO 2380 tho.
