Does Doebringer say that you shouldn't hold the pommel of a long sword?
He does say that. There's a discussion of that topic recently here:
http://www.thearma.org//forum/showflat.php?Cat=&Board=virtualclassroom&Number=12778&page=0&view=collapsed&sb=5&o=&fpart=1 However, the manuals all show people gripping at least half of their pommel (with the exception of "ball" pommels, where the hand butts up against it fully). Thus we're misunderstanding D. here, or he disagrees with other masters, or he's talking about ball and wheel pommels (which I believe were more common in his day...the scent-stopper is the predominant pommel in other works, IIRC...but I'm not a spatologist...)
