I've weathered the storm on here for around 9 years, I'll be aight

While true of the families of Cro-Mo and Cr-V in general, in impact sockets I've only ever seen 4140 used for Cro-Mo & 50BV30, 6140 & 6150 for Cr-V in factories I've dealt with (Japan, USA, Taiwan & China)

Well yes on paper I'd say that would be a strategy you could use. But we find that if the unknown Amazon brand or Ebay or Ali Express source is a fly by night company, and they are appealing to the user looking for lowest prices - those users probably dont own a $80,000 spectroscopy set up to...

One thing in common with all simple test lights from $15 no-name ones to $100 tool truck options is a fiddly finger pinching alligator clip on the ground cable that is annoying to use and easily rips off things. That's not finger pointing either - we make them too. Eric of SMA asked us to make...
