Thanks for the warm welcome guys,
The edge on the Scrapper 5 is now exactly 30 degrees inclusive, and was created on a Wicked Edge sharpener with diamond stones in gritsizes 100, 200, 400, and 600, after which i taped wet & dry paper to the stones in gritsizes 800, 1000, 1200, 1500, and 2000.
Last step was some no-name polishing compound on 2 pieces of cardboard, also taped to the diamond stones.
In contrast to what the pictures seem to show the edge is still not completely polished; for that i would need even finer wet & dry paper.
So in fact anyone with such a Wicked Edge (or an EdgePro for that matter) and enough patience should be able do it.
