Q: Do the blades have the precision balde on the back of the razor blade?

It appears to, I use it first to get off the “debris” from my face as it suggests in the instructions, then I shave with the razor and I get a very close shave. The back razor is good for trimming my mustache also.

Q: Is this a good razor for shaving your head?

Yes, it is. With its lubrication strip and exfoliating technology, you can get an exceptional head-shaving experience with our Exfoliating Razor. - The Gillette Team

Q: Does this razor blad handle support Gillette body cartridges

I believe it only works with Gillette lab blades not sure if that answers your questions

Q: What type/model blades are these?

Very disappointed with this new razor/blades. Rough “handling” resulting in nicks and minor irritation. Going back to my Gillette Fusion for sensitive skin. Plan to let Gillette know about dissatisfaction with new product.
