Review: Versatile, Reliable, Feels Good in the Hands. These are the ones you want. - If you are a Hobbyist, buy these. Skip the cheaper ones you can find. These were so good, that I ended up buying a size up, and an extra pair so I always have one in reach. These are a must have whenever I work on my 3d printers, Electronics etc. Pros - High quality and durable - Versatile and compatible with various connector types (JST, Molex, etc) - Precise and consistent crimping results - Comfortable handle / Feel Good to Use - Easy to use - High level of control Cons: - Expensive compared to others - You might need some practice before you master them (due to them being completely manual) - Doesn't work with barrel connectors (IE Spade, etc) that you commonly find at local hardware stores Additional Details: 2 versions of these pliers exist, Taiwan and Japanese made. I've had both in my hands but of different sizes. The Japanese ones are subjectively better, but I wouldn't return the Taiwanese ones. The only major difference is that the Japanese ones have the crimped connectors slide out easier. There are some minor visual differences as well. I mostly view these as a hobbyist tool, if I were using these everyday 9 to 5, I think I might get something else. They are very much a "do it once, do it right, take some more time to do it" type of tool instead of churning out millions of connectors. Though I'm unaware of anything better, these are just so dang good.
Review: Reliable, reproducible crimps. Worth the money. - I used to think crimping was a waste of time and money, especially since companies like Molex charge $Texas for "proper" crimpers. As a result I would normally solder terminals onto the ends of my wires, and sort of bend what was left with some needle-nose pliers to make it fit into the connector body. Then I did a couple projects where I spec'd PicoBlade connectors. These things are pretty diabolical and soldering them basically rendered them useless because they are so small, and the solder basically wicked everywhere you don't want it. Finally desperate enough, I decided to try the PA-09. It's well-built. Solid, no play in the joint, and does not shift or deform at all while you are doing the crimp. The grip is also solid. I would probably not want to do 100+ crimps in one sitting with this thing, but I can't imagine wanting to do that with any crimper. The docs are brief but effective. You want the sides of the connector to be parallel when you place it into the tool. If it's not, you picked the wrong size, and you will get bad results. I think I managed to destroy one PicoBlade terminal and after that I was producing perfectly serviceable crimps. I've gone on to crimp other terminals as well and it's unlikely I will go back to soldering them. One thing I would mention, and feel silly for not realizing at first. Normally you have to make two crimps to put a terminal on the end of a wire. One for the actual conductor, and another which crimps into the insulation as kind of a strain relief. I made the mistake of trying to use a larger size for the insulation crimp. They are the same size. It makes sense when you think about it, but of course I did not think about it.

## Features

### ⭐⭐⭐⭐⭐ Very good micro crimpers.
*by E***C on February 19, 2026*

These are very nice, precise crimpers. The pair I received are made in Japan. They may seem expensive, but you get what you pay for. I just repaired a Victron ve.direct cable and the crimps on the terminals are perfect. Now I can confidently make ve.direct cables to exact size instead of having a coil of extra wire to try and make tidy.
