Contrary to the comment on the page this ridge seems to be completed fairly commonly according to the hut book. I climbed it in 2005 and found the line a little loose and vague lower down but very pleasant higher up. The higher section consists of climbing over a serious of notches in a narrow ridge on solid rock
Change made - thank you for pointing this out.
This photo was taken from the Jegihorn which was climbed by the via ferrata. (click it to enlarge):
