By the way, since I suspect a lot of folks don't understand what I'm talking about regarding the circular vs. F-type (m-shaped) insulation crimp, here's a great image of itstolencopiedborrowed from Matt's Tech Pages: Common Wire-To-Board, Wire-To-Wire Connectors, and Crimp Tools:

The right terminal is a genuine Mini-PV (the real "DuPont" connector) crimped with the correct tool, the middle is a generic terminal crimped with the genuine tool, and the left is a generic terminal crimped with the PA-09. See how on the right two, the insulation crimp forms a tube around the insulation, hugging it without piercing it? That's what we want (for this terminal type). A tool with the F-type (m-shape) insulation crimp jaw forms the mess on the left: the tips of the insulation crimp wings have been pushed up and down, and then pierced into the insulation.
Here's what those terminals look like uncrimped (again, borrowed from the same page):

See how the insulation crimps are not symmetrical? They need the circular insulation jaw.
So what does the terminal with an F-type insulation crimp look like? Here's an AMPMODU MOD IV:

See how the insulation wings are flat and symmetrical? They're intended to be folded into the insulation, not around it.
they are important if you want to work with energy storage etc
I just want to throw in my recent experience with crimping JST-XH connectors.
There is another set though, with an unnamed crimper. That one turned out to be a SN-01BM, with a much narrower jaw. This fits the connector as it should, and now knowing more about crimping, i got an adequate crimp on the first try.
If you look at the other pictures on the amazon listing, it looks like it’s the same jaws as in the SN-4228B I posted about in the original post. (But with nicer handles.)

Did something change with one of the vendors? The link you posted for the TZ-4228B leads to a tool with 4 crimp positions for me, with the innermost one rounded. And the Amazon one for the Preciva PR-3254 shows 3.
