I do not know of a single Single Edge razor that is a slant. A slant razor hold the blade at an angle. This torques the blade. This causes the blade to bend. This means that they are usually (if not all) DE blades as they are thinner and can bend. SE blades are thicker and do not lend themselves to bend.That shows what I know, I thought slants were single edge. Are you sayingsthat not all single edge razors are slants? What are the differences between them?
Cool ad by the way
There are a few SE style blades. Some look like scraper blades that are available at the hardware store. They are not the same as the blades designated for shaving are a lot sharper. Others are thinner and fit Injector razors. Then there are FHS blades which fit a OneBlade razor. There are a few more, but those are the most common.
