What is this called and how to do it?

[Inky Doc]

I'm wanting to know how to do that bubbly-looking effect.  Also, I'm assuming it is simply block dyed after its tooled. Am I correct? 

Edit: the larger "bubbles" are the subject of my question  

Thank you kindly.

That is a matting stamp-https://www.tandyleather.com/en/product/m884-craftool-matting-stamp

My apologies, but that is a different tool. I have that matting stamp, the entire face of that tool is about the size of a dime. The "bubbles" in the picture are each about the size of a pea. However, when there is nothing to show relative size the appearance is very similar to one another. 

 

Edit: The tool you referenced is what does the smaller, tiny bubbles next to the larger ones.

My bad, I tried

I appreciate it and hope my last post didn't seem rude. Thank you again and have a great weekend.

No worries

Possibly some kind of home made stamp?

I think it still is a type of matting stamp, but not one that is available from Tandy.  There are a couple of makers out of eastern Europe that sell into the US with tools that are like this.  One of them, Sergey, is on here.  You might ask him if this is some of his work.

It looks like it would just be a tool with a rounded hemispherical end.

Check this post and see if it looks like any of the tools there:

I bought an 89 cent screwdriver and a small box of furniture tacks. Next I hacksawed the screwdriver where the metal post meets the plastic handle. Then heated the sharp point of one of the tacks and then buried it to the head. Problem solved, total cost about $2.50.

I think those are not bubbles, those are depressions (optical illusion). Done with a Pear-Shader (tilted) or similar stamp maybe.

I second that opinion.  There doesn't seem to be a unified pattern there like you would expect from a stamp.

Nice idea but that isn't going to get you where you want to go.  The pear shader is probably the answer.  Most of the depressions are similar and some seem to be "siamese twins" next to one-another.

They are indeed depressions. The tool I made recreates the effect quite nicely. I've only messed around with it for a few minutes but was able to easily make the different nuances that are displayed in the pic at the top of the thread. I also guessed that someone more skilled than I accomplished the same with a smooth pear shader.

looks like a smooth pear shader twisted randomly between each strike

That looks like a Duane Ballard piece. He is a super cool dude just email him and ask. I would be surprised if he did not answer you.
