Yup, this is as big a crash as I remember...

Anyway: yes, I keep hearing inappropriate angle may lead to more scraping, and so - razor burn. A duller edge may prompt you to press more with the same results.

One thing I think may help is establishing a clear definition of razor burn, and also taking good quality photos to illustrate.

I am saying this, because I am not sure what is and isn't razor burn. I have never had any redness linger for several days as some complain. Never had burn suddenly appear several hours after I finish my shave, as others say. On the other hand, I have used bad angles and more pressure and gotten some redness (it disappeared in say 30 min) and I have also had my face *burn* from soaps and creams before I even start shaving. Of course, these are different. So what exactly is razor burn?
