I also sell 'every' engraving tool there is, on the 'Engraving Tool' Vendor at my Miranda's home and even more extra spellbook scriby engraving tools are also next door at my Hughes home.
And there are always extra wood engraving tools, always also placed in her Storage Solutions vendors, with the large chests armoires etc.
Both homes are located west of Umbra, way west as one would go out to Iantown, or the Enchanted Forest with all the pixies, North Gravewater Lakeshore ...west of Umbra. Just follow the lake and desert,west from Umbra, towards Iantown, second 18x18 log cabin, with all the carpentry items.
I restock daily.
