Years ago I took a bowl turning class from Knud Oland. He used just two scrapers like these to make bowls from rough blank to finish. He also made and sold these scrapers and I bought these from him. I used these two scrapers to make many bowls until I sold my lathe when I moved to a smaller shop. $150 OBO for both including extra HSS bits and allen wrenches. Pick up near Greensboro or happy to ship if you pay postage. Glad to answer any questions.
