Eisenport
From Scholar Victoria
Iron Gate
A kind of pflug guard held centrally with the tip somewhat elevated above the eye line to provide excellent parrying capability at the expense of thrusting counter, in fact a slightly extended eisenport position is often used to describe the gerade versetzung (straight parrying).
The image of the eisenport shown here is using the rappier, however the longsword version is identical in most respects (except that two hands are used, of course).
Meyer sometimes uses the term eisenport to refer to his schranckhut/cross (he calls this the Italian usage of eisenport; in this case we will refer to that guard accordingly.
