PA-09? Really?
whats your problem with the PA-09?
Well it is does not insure you complete the crimp, as does a tool with a ratchet.
It does not have replaceable/interchangeable "jaws".
It requires you to make two crimps rather than one.
And, at $39, it costs way too much for a tool as simple as it is.
The one I use and referenced is $23, which is nearly half the price of the PA-09 and has all of the features I mentioned that that PA-09 does not have.
To each their own but paying more for an inferior tool seems curious to me.

I'm sorry but that's just not the case, the PA09 if used correctly by someone who knows what they are doing produces perfect crimps...

Of course you can make good crimps with it. I could make good crimps with a pair of needle nose pliers if I had to. I've been in the industry for more years than I care to remember.
But why pay more for a tool that does less?

i have both the mdpc crimp tool and the pa-09.
I find that i use the pa-09 far more often. -

The advantage of Engineer's type of crimpers is that they are simple and more versatile. No need to change jaws and you can adapt independently to core an insulation crimping. A perfect tool for one-offs hobby and lab environment.
You will seldom find them in more professional and production environments when consistent quality is important. In those places, people typically use very expensive tools that are certified for the terminals being used.
As for the price, yes Engineer's crimpers are over priced and inferior IMO to this one https://iwiss.com/product/micro-open-barrel-crimping-tools-work-on-awg28-20-awg24-12-jam-molex-tyco-jst-terminals-and-connectors/

Here let me fix that for you : why pay more for a tool that "in my opinion" does less, the key word in that sentence is "opinion" and you know that opinions are like arseholes, everyone has one...

IMO all crimping tools are crap because they aren't designed to be used by human beings with only two hands.

True that!

I have more crimping tools than I care to admit; but we're hobbyists, we don't do mass production so its for the most part quicker to grab the PA-09 from the desk than to go look for the correct crimper.
And in skilled hands it will allow you to make good crimps on things that don't really fit. I recently found myself crimping a 3mm delicate silicone heater wire to #26 wire with a but splice U terminal, and with careful manipulation of the terminal with the PA-09 I was able to get a good crimp both on the nichrome/fiberglass core, silicone sheath as well as the #26 wire. Can't do that with a fixed tool.

That why I prefer PA-09-like tools: it is much easier to insert the pin in the jaws, the insert the wire and crimp it. Ok, it needs two operations, but as someone said, it is much more universal.
I tried the PA-09 (and was planning to buy one), and found a big issue: the width is too small for Dupont connectors, which are the connectors I mostly use (for Arduinos).
So, I plan to order this one:
I use it at work, and it is very good, producing high quality crimping. But, as I said, I mostly use Dupont, and I don't know how it goes on smaller pins...
I admit it is pricy, though.

You lost me there. Why are two hands not enough?

one hand to hold the crimp tool. one to hold the connector and one to hold the cable.

People need to learn how to use tools properly.
I’m still boggled that anyone would choose those janky manual crimpers over a proper set. This goes to show that people are unwilling to learn to do things properly, and are much happier to do a worse job if it seems easier to them. Yikes.

I find the issue of matching the jaws to the pins I crimp to be confusing. For example, if I use KF2510 connectors from Ali, what are the correct jaws? The open style crimpers from Engineer iSwiss and others make it easier for me. I find the matching slot for the core and the insulation respectively and crimp.

I've tried and tried but using crimping tools is just one of those things that I can't master. In my 65 year on this planet, I've been able to master most things. I can use just about any tool making machine - mill, lathe, surface grinder centre grinder. I can weld and braze (up to a point) and solder. I can bend pipes and fold sheet metal. I can route, plane, cut and join timber using both hand and machine tools. I can strip and re-build engines gearboxes, carburettors and distributors. I can fit kitchens and bathrooms and central heating systems. I can cut and fit tiles, build my own furniture, design and build my own printer. I have a reasonable understanding of basic electronics and I've build a few Arduino and before that PIC based projects. For someone my age, I'm reasonably "tech savvy". As well as 3D printing, my hobbies include photography (still and video), and model making (scratch build as well as kits).
But there are two things that drive me up the wall and just make me want to throw the tools through the nearest window (or at the first person to make some comment). The first is plastering - I can make it either smooth or flat but not both. I've tried and tried but every time I end up needing a belt sander (which makes such a mess and upsets 'er in doors no end). The second thing is using a bloody crimping tool (and I've bought numerous ones). I either fit the terminal into the tool upside down or back to front, then it either falls out or I flatten it too much before I can get the bloody wire in. I can get a good crimp on the bare conductors, or I can get a good crimp on the insulation but never both together. Two hands definitely aren't enough and using teeth or toes doesn't help all that much either (I've tried).
I have now mastered a technique which works well for me. It involves holding the wire in a vice, the terminal in one hand, and making the crimp with a pair of curved needle nosed pliers. Since I've developed that way of doing things, I've never suffered from a bad crimps whereas before, I had numerous problems when using the proper "tool".
Knowing that using a crimping tool is just a matter of learning the "technique" doesn't help. It's just like plastering - I can't do it - end of.....................

Whether you think you can or you can't, it's true.

A "proper set" isn't an option for most hobbyist users. A chinesium set is either not proper or not cheap after all.
As long as I can quickly and easily crimp terminals that are crimpt so the wire break at some arbitrary point and not in the crimp or pulled out then its good enough, fast enough and cheaper than a proper set. It won't be for everyone, thats fine.
-
With the manual crimpers, you can't be sure that you're making a reliable crimp unless you test every single one. Except, the test is destructive... so... you can not be sure that any of your crimps are good.
The consistency of the pressure provided by the ratcheting tools is the key to a good crimp.
-
I'd say that has to do with experience; I don't use a torque wrench for every screw at home either.
I'll tell you what, if you're ever in my area you can test every crimp on my printer. If one fails drinks are one me..
