...but I find the new-style prism pole points to be way too blunt for my purposes. I chuck them in a drill press and use a grit cylinder in a Dremel tool to sharpen them, otherwise I can't get them to stay on marks with small dimples. I wish the manufacturers would save me the trouble.
I think SECO supply sharp and blunt versions of these?

Considering that the standard control point I set is a spike with about a 1mm punchmark on the head, yes, that child-safe rounded point would be useless. Another entry into the Department of What Were They Thinking? .
Seco Sharp Point 5194-003
Does anyone still make the tips that use replaceable plumb bob points?
They are shown in the current SECO catalogue, part number 6000-002.
Thanks for the 6 a.m. ear worm. Now you can have it too:

Why would anybody want the blunt ones? Why did they start making them that way?

I guess too many kiddies were hurting themselves with proper equipment points. It rates right up there with their hugs and participation trophies...

Hah! Yea I'm sure there's a big crisis with kids being exposed to and injured by survey gear.
I'm putting forward legislation to ban prism pole points of the pointy variety and allow only topo shoes and the blunt-type points. I hope the rest of you can get behind me for the sake of our children and the survival of this great nation.

The last time I ordered the sharp points I received the dull ones shown in my photo. Maybe they shipped the wrong part number. I just ordered a couple more, I'm interested to see what shows up.

You must have watched the most recent episode of The Simpsons. That's the one where Homer invests big in manufacturing trophies because there seems to be a never ending need for them. Of course he is ruined when the world changes and no one ever gets a trophy for any reason.
The blunt points are repurposed tripod shoe points.
they should have two tips that are the same exact length. One with a completely flat bottom, and the other with a sharp tip. Switch them out as needed.
The packets of the almost identical part numbers look the same and may be in the same bin.
Many little parts like this get confused in the stock room
It helps to tell them your last order did not get you what you want.
I have found it necessary to talk to the person as they go to the bin and double check part numbers and to swap pictures if necessary as they fetch what I need to insure getting what I want.
Ever since day one, they have been helpful and understanding that I want a certain part and will happily get me that part.
The tripod points are all rounded and have the same thread size also come in an extra short size and an extra long size for setting up on different surfaces.
I accidentally stabbed my chainman in the top of his thigh while climbing a steep rocky ledge. I went to plant the rod into the ground and wound up losing control of it and plunged it in pretty deep. He said he thinks I put a dimple in his femur. I was 19 at the time. So yeah, sharp things and kids...

Presumably these sharp points are only used for low frequency control work an not bulk topo - I mentioned in another thread that we wore down a good 5mm of tip in a 60,000 shot urban topo.

That's the reason I use a topo shoe when doing topo, even if it's all hardscape. Whenever I need to set a control point or tie a monument, I just slip off the shoe and I still have a nice point to work with.
[SARCASM]They probably can't send the sharp points to California without them being individually labeled "This package contains Items known to the state of California to be SHARP!!!!"[/SARCASM] 😉
My sharp points were delivered yesterday. They're definitely an improvement over the blunt ones (on the left):
I still want to tune up the point so that it catches on small dimples, but that'll take much less work compared to what I've had to do to get the blunt ones in shape.
