1/2” bg’s are my experimenters - try new grinds with them, as I find no real other use for them. I can do anything with a 5/8” that a 1/2” will do. 2x 5/8” (45* for initial roughing, 60* to the finish) and a 3/8” have a Hannes hatmaker grind.
The 45* rougher is one of Lyle’s signature Thompson 5/8” wide V’s, the V10 material holds up best getting through bark and inclusions during initial roughing, and the wide V hogs material without clogging.
