It's the Bahco 625 Premium Ergonomic Carbide Scraper in the 1-inch size. The gasket on my '90 VFR's clutch cover was applied at some point with gasket cement and would have been a real challenge without this little gem. It fits your hand perfectly ("ergonomic") and will scrape the surface easily and completely, moving forward or back.
The blade has three surfaces and is replaceable — shaped blades are also available. Unlike most scrapers and even razor blades, this tool doesn't want to dig into the soft aluminum surfaces. My first thought was that $17 is a lot of dinero for a gasket scraper, but when a tool works this well, it's money well spent. Recommended.
