Well the last two days I have given myself the best str8 shaves so far. After almost two months I have been able to get a near-BBS shave two days in a row. That's the good news, but there is a problem: razor burn.

What I discovered that has given me a better shave is that I need to hold the blade at a much steeper angle than I expected. I find this angle by slowly increasing the angle until I can hear the blade make a sandpaper noise. At that point the whiskers start coming off. But I think this steep angle may be contributing to my razor burn.

Here is my question: Does the need for a steeper angle increase with duller blades? Is my real problem that the blade isn't sharp enough?
