Actually again, for a blind welt you hide the welt and the stitches by leaving more of the outsole at the edge and then pull it over the welt covering it completely. You can see it in this post, Meccariello does the common thing and then Hiro Yanagimachi does a blind welt at the waist: http://shoegazing.se/english/2015/11/04/competition-winners-and-answers-of-find-the-difference/
Back in the days when you referred to a bevelled waist, it was a one with a blind welt, nowadays it's just the rounded shape.
Loved that link! Should be required reading along with the first half a dozen pages in the SF Shoemaking Techniques and Traditions...These Foolish Things thread.
