I did the soap/dish/badger brush thing for a couple of years, but couldn't find any nice soaps that didn't cost a fortune....where do you buy Astra blades and a razor to run them..??...
Double-edged and a can of Barbasol is what I cut my chin on...

Warm that face, get it wet with hot water, use some warm lather and these razors cut through the hair like butter.
Thats the blades, only 9.75 shipped per 100, look at the bottom and you see options for shaving soap. I use prorasro senstive, and a can of that stuff will last 4-6 months if you shave every day. It only takes a very little dab to lather your entire face. That 100 blade pack lasts a while also. I get at least 3-4 shaves from a blade, sometimes more, and my beard is coarse. You can feel when it's time to change the blade.
Also you can check ebay for double edge razors. They make adjustables which may be good for those not looking for as an aggressive of a shave (angle of the blade can be dialed down if you are prone to cutting yourself, but it may take more passes to get it smooth when you dial it down.
With that heavy Merkur slant barber, I can get it smooth in one pass, it's an aggressive razor with a good amount of exposed blade. I started on that adjustable gillette safety razor until I was comfortable.
Here is a store that sells double edge safety razors.

Check Ebay for vintage razors, (Like the old gillettes) clean them with alcohol for sanitizing and mineral oil for cleaning, and they are GTG.
