I had never considered trying this steep-angle (of the blade) approach before, because I was concerned about the scraping action of the blade leaving increased irritation in its wake.
But since I'm mister question everything, I figured that I should test even my own pre-conceived ideas.
The bottom line on this one is that my intuition was correct in that there was more lingering irritation after the shave. However, as I also suspected, much like a wood worker uses a hand scraper instead of sandpaper to get an ultra smooth finish, the slightly-more-scraping action of the edge on the beard also gave me a close shave in two passes (with grain, then against grain), with very few wounds -- just a couple of tiny weepers. The ability to pivot the shaving angle on the blade guard also gave me good control of the blade edge against skin.
In fact, this has caused me to once again rethink the use of my Gillette Slim Adjustable. I may just pull that out of the shaving box in my closet, set it to a fairly generous blade exposure, and give it a go using this steep-angle technique.
Hmmm. I guess an old dog can learn new tricks!
