I have been experimenting with my Aldi's at 22* for several months now, and use them for paring. So far, so good.
To remove the wire edge, I work the back as others suggest. Then I use a trick that I think I got from one of Charles Hayward's articles..... I make 1-2 passes down the length of the bevel, on the corner of a softwood block - like a knife slice, pendicular to the corner. It works for me, anyway.
