How are these working out for you? I just won a bid on a Gillette Slim Adjustable over the weekend, it is a 1963 model, older than me. Should be in the mail box tomorrow or Thursday. I'm going to give it a really good cleaning and try it this Saturday. I'm looking forward to using it for face shaving only, for now, perhaps I'll try it on the dome after I get the hang of it.
ugabulldog, Try a different blade. http://www.westcoastshaving.com/ has sample packs so you can see what blade works best for you.I save the DE headshave for special occasions. I have found that they are closer, last longer & the shadow is no where NEAR as dark as what I have with a HB. With that said, it takes me almost 20 minutes, so I don't do it often.When I DO shave my head with a DE, I use a Gillette tech and Wal-mart DE blades. I use Merkur Super Platinum blades on my face with a Gelette SuperSpeed Blue Tip
I learned to shave my face with a DE , and recently went back to trying it out for a while. There is a reason why they are not in popular demand any more . That is in... IMO because a regular two bladed razor ( not 4&5 ) is much superior than a DE. The 4,5,6 bladed razor are a different story on your face, just a bunch of hype and WAY over priced. Shaving your head with a multi bladed razor I think is fine but my head does not require there use.
