I've found myself accumulating quite a few myself now! An Engineer PA-24 came my way a few days ago, it's quite small and lightweight as crimping tools go, but needs two actions for each crimp, one for the strain relief and the other for the connection itself. It does have both B and O crimps. I haven't tried it other than a couple of test crimps yet, so the jury's out. Although it needs two actions, it may be less fiddly than trying to align a connector in a dual-action crimp tool.

The PA-24 is explicitly designed for: JST PH, NH, XH; Molex 43030, 1560; TE EI; and Amphenol QI/Dupont.

The PA-24 O crimpers are 1.4 and 1.8mm. The B crimpers are 1.3, 1.6, 1.9 and 2.2mm.

Both TE EI and Dupont use O crimps on the strain relief.

Have you accumulated any more insight over the past month and change?

PWS-PLUS 001, Mfr# 40024, 26-36 AWG, white thumb push
PWS-PLUS 002, Mfr# 40025, 20-30 AWG, red thumb push
PWS-PLUS 003, Mfr# 40026, 18-28 AWG, blue thumb push

Be aware that Knipex also sell a seemingly identical PWS-PLUS 001 and PWS-PLUS 003. These are not the same! Most importantly, unlike the cheaper Jokari versions, the Knipex versions don't have a guide that goes down to the very short strip length required for these crimp connections. You can still strip with the Knipex versions, but you'll usually find that you have an extra step of trimming after stripping.

FYI, I don’t think that’s a difference between Jokari and Knipex, but rather between older and newer production runs. Earlier Jokari-branded ones also lack the little “nose” that allows for shorter strip lengths. If you do a google image search for the Jokari models, you’ll see pictures of both styles.
