It all depends on the shaving razor. Here is an image from TSA depicting the different types of razors and the TSA rules for each.
Yes, According to TSA you can have a Safety razor double edge or single edge in your checked luggage or carry-on luggage on the plane without blades.
TSA does not allow for you to carry any type of razor blades in your carry on luggage. They may be placed in your checked luggage. Just make sure you put them in a safe place that is well protected in order to not harm you or others while going through your luggage.
Razor blades in your Carry on Bags is strictly prohibited and not allowed on any flights.
According to TSA guidelines straight razors must be in checked luggage and strictly prohibited in carry on bags.
TSA classified disposable razors in two categories. One with a single piece razor with handle and head that is not interchangeable. The other being a cartridge type razor where you can replace the head and keep the handle.
Both types of razors are considered disposable by TSA and are permitted in both carry on luggage and checked luggage
Checked luggage is approved.
Carry on approved if it is less than 3.4 ounces/100ml per TSA guidelines
This one is a bit more tricky since there are no official guidelines for Shaving Soap that I came across from TSA. Here is my story instead.
