The scheme for a Pioneer Yardstick gives Artisan Pioneer Yardstick.

It's worth noting that the non-artisan version is a measure. I don't have the schemes nor the learned recipes for the forager's or scrapper's versions, but I'm assuming that a similar bug could also be present due to the non-artisan versions being called measures, and the artisan versions being tapes and squares, respectively.

PlagueBlack supplied me with an image - he learned the recipe shown and was given the artisan version.
