I acquired my Edelrid Hannibal from Backcountry Gear in 2017.
The Edelrid Hannibal is forged from aluminum alloy and then soft anodized. Mine is 131 mm. tall, 74 mm. wide, and 13 mm. thick. The rope hole is 46 mm. high and 50 mm. wide. The top center thickness is 11 mm. The shaft length and width are 31 mm. and 31 mm., respectively. The eye measures 15 mm. by 15 mm. and has a black o-ring seated in an internal groove. The top and bottom ears are 14 and 6.5 mm. long, respectively. My Edelrid Hannibal weighs 103 g.
One side is forged with "EDELRID," "HANNIBAL," and a rigging icon. The other side is forged with "EDELRID," "Ø 7,8-12,0," "EN 15151-2," and a book-with-an-"i" icon.
The Edelrid Hannibal falls into my miscellaneous figure eights with ears category. The ears allow for some alternate rigging configurations (like those described for the Petzl Pirana), and can also be used to facilitate tie-offs. Unlike the ears on many eights, these don't seem to get in the way, and they don't make the eight absurdly large.
The eye is small, and many standard carabiners will not fit. Forget about trying to get two to fit. Plan on dedicating a carabiner if you want to use this eight; otherwise, expect a lot of hassle. I wish folks would give up on the o-ring eye idea.
The slot is nonfunctional, being far too small for belaying.
