You’re so right. I googled “Zenport ZJ68A Replacement Blades” and see my error now.
The good thing is they are available. Mine for my much more expensive tool are outrageously expensive. For 25$ for new blades for this Zenport which you won’t need blades for years I imagine, that’s not a big investment like mine are.
Wishing you all luck. I’m going to get one of these tools too, eventually.
