The Wire Stripper I think you saw last time was this one: https://littlebirdelectronics.com.au/products/wire-strippers. This part came from Seeed Studio. We no longer carry Seeed Studio parts on a “just in time” basis as their shipping isn’t punctual.
A good alternative is this one which has 30, 28, 26, 24, 22, 20 AWG settings
As always, please don’t hesitate to contact me if you have any questions or queries whatsoever!
