Upside-Down and Inside-Out: how to scrape double reeds following historical sources

This is my own reconstruction of the historical technique for scraping reeds for historical double reed instruments, following historical sources; This can be used for baroque and classical bassoon, curtals/dulcians of all sizes, historical oboes, shawms, historical bagpipe reeds, and more!
