hard, sharp meter probes that can withstand being used to scratch components?

Makes more sense to buy a pack of these if needing to place an obvious mark on so many fried components:

One can easy spend more on a set of good DMM leads than a 6 pack of white markers.

I will explain this to clear up any confusion about my situation. I literally mark upwards of 1000 of these components a day, 6 days a week. with how I do it, a component tests bad, I scratch it with the probe already in my hand, and test the next component.

if I were to use a sharpie, for example, I would have to put down both probes, pick up the sharpie, take off the lid, mark the component (make sure it's the right one becasuse now I had to take my eyes out of my microscope), put the cap back on, pick up my probes, go back to the scope and carry on.

if you could do that all in 3 seconds, it would add about 50 minutes to my average work day.

don't mistake laziness for efficiency.

anyhow, I'm going to try this tungstun bit approach, but if that doesn't work, making a probe out of a tungsten awl is an excellent back up plan

Bud:
Gee..., you guys have that many lightnings in your location?
I' think a pair of machinist scribes with cold welded to them multimeter wire leads would set you for long time.

Pomona 6341 I dislike because they have an aluminium tube for the probe sheath and the dissimilar metals sucked for contact resistance and it's soft.
OP when you get yours, please check if this has changed as I complained to Pomona.
Their gold plated probes don't have this problem but are spring-loaded.

Best I've used is Huntron Tracker MP20 or MP10 I can't remember but I thought they are tungsten and telescoping.

For poking through conformal coatings, I have best luck using SS dental picks with an attached test lead.
Another approach is making your own probe using sewing needles and old ball point pens. I've done that on the cheap.
thom:
they should be here on monday, if you have any specific thing you would like me to do to test them, let me know! if the socket is in fact soft aluminum, I have a feeling no matter what tips I use, I'm going to wear it out fast just from the way I use these things, but we will see.

I've never even heard of those huntron probes, I'll add those to the list I'll try if these pomona don't live up
