I like that. I have an automotive pain-in-the- coming up where that would come in very handy. I might even have one of those scalpel handles in the shed.

Well I've lost count of the number of times I've slipped and stabbed myself with sharp meter probes trying to pierce car looms, I think with one of these I'd soon be missing fingers or A and E's best customer!

Indeed. When I was much younger I dropped one of those scalpels on my leg. It just sat there upright wobbling. Went quite deep. I pulled it out quickly, applied pressure and pretended it never happened which worked nicely thank goodness.

I think that probe would end up a blood bath.

Edit: think I’m accident prone. Literally sitting here eating my breakfast and just noticed I managed to cut my finger. I have no idea how that even happened.

Many years ago I underwent 'lumpectomy' under local anaesthetic on my hand. The surgeon used a vaguely-similar 'electric scalpel' at one point, the cutting edge being RF-excited to cauterize the blood-vessels as it cut.

It was sort-of worrying to see the smoke rising - but it worked - no more lump!

It's the description of "Handy" that worries me, as in "sticks in your handy".

I do a bit of automotive electricianing and will stay with my nice commercial 'pin-prick' clamping probes .

Hmmm, so did I the other day trying to find the LH and RH flasher wires up under the dash of a Ford D-series.

With the very probe pictured too

Does anyone make a nice little probe with a hooked end and a screw operated needle or some such? It wouldn't do for the SMD stuff, but for cable tracing it would be great. A sort of small version of the coax cable outer stripper thing comes to mind.

The ones I have (and like very much) are quite like these ones https://canada.newark.com/hirschmann...be/dp/06WX5804

The Hirschmann ones extend two little hooks which open and close as you pull or release the finger guard. Mine look so similar but open a little anvil opposite a fine pointed contact which will penetrate insulation. Mine ( I've owned them some years) are branded "Texas" and I cannot now find anything about them on the internet.
