I'm not sure if I get why you would have two identical ends. Having two different diameter ends lets you use it in more situations by being able to flip it. In that sense, that was a feature of the original that I really liked.
As for the round end, I think it may be a problem, but I also think some people may love it. I'd be worried that the round end wouldn't hold up to repeated heavy hammer strikes, so that kind of kills this as a double ended tool. But for those guys working sheet metal with bossing hammers, this might be a nice way to get better reach into a deeply dished piece of metal (say inside a motorcycle tank).
If I were designing this, I'd also look for a way to keep it from rolling off a table.
I mentioned in the other thread that if you lengthened the collar a little, it would make a great deadblow carver's mallet. Even as drawn above, I think it would be pretty good. But rethinking that made me think of a more fundamental physics issue. You're planning on making a tool that transfers an impact, like the center ball in a Newton's cradle. A deadblow hammer works by setting the shot against the back of the hammer during the swing, and that shot then falls upon the inside of the hammer face following the impact. But the catch is that except as a carver's mallet, this isn't a tool you will be swinging. No swing, means the shot never gets reset to the back of the cavity, so the shot inside doesn't do anything useful (though it won't hurt, so that's ok I guess).

I'm not sure why...
But my wife likes the looks of those tools?

Maybe offer a couple of different styles? As long as the numbers doing it that way make sense.

I prefer the original for the same reason as above. 2 different diameter heads makes it more versatile.

Of the three I would prefer the top one. The round end looks like it would be prone to slip. I second adding a flat spot on the side if feasible so it doesn’t roll away.

I like the looks of the top one, as the one end looks smaller for driving pins and other smaller diameter things. I think the original design with a larger end on one side would be benificial in some instances but I’d think more heavy equipment mechanics would prefer a 1”-1.5” diameter small end. The rounded ends make no sense to me. It’s not reversible, and if it was wouldn’t be useful always rolling off pins, or deadblow strikes

I’ll buy a green top one or original one. Just invoice me. Lol

Once I opened this I thought it was maybe TC's April Fools joke a few days early.
What's the reasoning or predicted use for the rounded end of it? I would think like others that having different diameter ends would be more useful than having a rounded end.

screw on or maybe even slip on interchangeble tips come to mind.

Are we going to resurrect the maxi-min?

For me the top one would be my choice. The rounded ones might be okay for sheet metal work?

Thanks for the great feedback here. Feel free to keep it coming. I'll be printing up and circulating the feedback.

Just remember that if you take every bit our our advice, you'll end up with something like this:
I agree with the idea of different head sizes. It is really being used just like a punch. You want the smallest surface area possible to deliver the most force to your work piece to make it move but just large/soft enough to not mar it.

Best bet would be two flat ends, but different diameters. Or thats what I would get the best use out of anyways.
