I briefly had an aluminum PAA DOC flat bottom ascension. I had the same problem with the teeth. I got very good shaves with it and I liked the light weight, but the sharp teeth made the shave very uncomfortable. Since I don't use open comb razors very often, I thought maybe it was the blade. So I dusted off my Gillette NEW Deluxe, and had a great comfortable shave. It's a shame the teeth are so sharp as I really did get good shaves with it. I think the stainless steel model may be a bit too heavy for my liking.
