Replying to Straight Razor = Less Razor Burn?

So for my current job I have to shave just about everyday and because I have pretty sensitive skin, I get pretty bad razor burn. A buddy of mine told me to start using a single blade straight old school razor. Just wondering if anyone has had any experience using on of these, and if it has reduced the amount of razor burn. I get the most razor burn on my neck....And no this is not for shaving my balls and there will be no peeing in butts.
