I have been wet shaving for about 6 years but always with cartridge razors, most recently the ProGlide. I have always gotten a reasonable shave but got fed up with the high cost of new cartridges and ended up landing here on B&B during my search for a better way. I ordered three DEs to try out (a new Weber DLC, a NOS Simplex Military Razor, and a Gillette Fat Boy adjustable). As I was waiting for the razors to arrive I stumbled upon my Grandfather-in-Laws old razor and decided to give it a try (admittedly after first cleaning, polishing, and sanitizing it). As usual I used Proraso pre-shave and my wifes homemade shaving soap on each pass. I threw a new Merkur Super Platinum blade in the old razor and gave it a shot. I started with a WTG pass and two XTG passes and was very disappointed with the patchy shave I got. I decided to just go for it and do an ATG and that is when I realized I was holding the razor all wrong on the previous three passes and got the closest shave I have ever had. Unfortunately I also got the worst razor burn I have ever had! It looks like I have a lot of technique to learn, but at least I know what I have been missing using cartridge razors all these years. I have decided to gift the old razor to my father-in-law who will appreciate the razor as a connection to his father. I was hoping to provide him with a some general information about it but I am having trouble identifying it. I think it is a Gillette No 66, but any help would be greatly appreciated!
