There is one that supposedly can do ‘bud grafting’, and something called ‘English Double Notch’ grafting. as well as ‘V graft’, and ‘omega’ grafting, and it’s made in Italy INNESTATRICE MANUALE 4T
Here is a video of it being used, I think he used the Omega graft
Here are two more places selling it

(This one does not appear to have the ‘English Double Notch’ grafting blade, unless they just forgot to update the ad for the newest model) Vasili's Garden
As well as the replacement blades Cerca
I wonder how good it works for the bud grafting and for the ‘English Double Notch’ grafting, ‘English Double Notch’ grafting seems to look a lot like Z grafting to me.
