Not sure you will like the stamped metal crimper - the little pins are difficult to crimp once - never mind twice.
I used this one for my well over 100 pins for Dupont connectors.
It has a small side and fat side to accommodate the pin and the insulator on the wire.
Overall its pretty good - I've seem many that are nearly identical to this.
Here are the crimps:
There is a very slight difference between the two.
The red one I crimped once.
The green one I crimped as usual - then I opened the crimper - pushed the wire in another 1/16" and gave it a 1/2 crimp to compress the insulator better.
What was happening is that the connector would go most of the way in and get stuck at the bulge where the pin grips the wire..
The extra little crimp compressed the insulator and bulge enough to make it go into the Dupont connector easily..
I figured this out after fighting to get wires in for a 30-40 wires.
If I were designing my own - I'd make the wire insulator side of the jaw twice as wide so I could do this in one crimp..
Maybe I should patent that
