Yep, ball-end old type. I certainly doesn't look like any cracks, so that's good. It's a nice shaver, and bit more aggressive than your other razors. As far as aggressive razors go though, I think it's a good place to start. It's got moderate blade exposure, but pretty much a non-existent gap between blade and the combs, which ups the safety factor a bit.
