Edit: ooh just found a batch of unicorn dung outside of eBay. Going to to camp that like a tick on a dog.

You are familiar with the removal method of ticks camping on a dog I take it? Just pray you don't get the same treatment or you'll know how that resistor felt. [emoji44]

These HV probes are not made for general diag work; they are made for a specific purpose: to measure the HV at the anode on a CRT while it is still in-circuit. That extra-long probe tip is made to be able to work under the big rubber cap without damaging it; some of these are 3" across and will tear easily, so the probe is made long & thin. I have a stand-alone B&K model HV-44 I leave hanging from a pin on the wall which I call "The Probulator"; it's mostly there for my own perverse amusement rather than any useful purpose.

Later versions, like the 44A on the right, have a shorter probe tip and a shrouded neck like you're suggesting; these are more meant for work with projection TV focus blocks and HV dividers.

Arh now that does make sense but really limits its usage because if you tried to to use it on any other HV point there would be a serious threat of a flash over if the exposed tip came close to anything else.

My dad didn't do that, he never knew your sister🤣. He used a freshly drawn cigarette so the tip nicely glowing and applied that to their arse. As soon as they released their bite they were squashed with tweezers, nice way to meet your end.
