The cover fits perfectly, one has to start dragged back and forth a little, hey presto! everything fits and even looks good.
The only drawback to the sheath is, as a Vorrezensend has indicated: The envelope is at the rear of a little far, so this is a little protruding in the middle. "Strapped" is therefore the wrong word. At this point I would have liked the envelope a little more closely. But presumably could then no longer so easy "about it evert", as it was the case now.
