Blame Ernesto. Must have looked cool to have straight blades back in 1989.
Since Nova never has their disc blades nowadays, I gave up on the idea of bending them. Probably have to get a longer lever for my bender, and I figure there would be a learning curve where I waste at least a couple blades. The Reynolds raked fork blades aren't exactly the curve I would like, but close enough. You just miter the mount to the blade.
